DescriptionAutomatic circuit reclosers are recognized by electric utilities throughout the world as an essential device for achieving their prime goal: providing maximum continuity of electric service to their customers simply and economically .

Reclosers sense and interrupt fault currents and automatically restore service after momentary outage .

The automatic circuit recloser is essentially a self-contained device with the necessary intelligence to sense overcurrents to time and interrupt fault currents and to re-energize the line by reclosing automatically . If a fault is permanent, the recloser locks open after a preset number of operations (usually three or four), isolating the faulted section from the main part of the system .

Temporary faultsExtensive studies of overhead distribution systems have established that approximately 80 to 95 percent of all system faults are temporary in nature and, at most, last from only a few cycles to a few seconds .

Typical causes of these temporary faults are:• Windblown conductors touching one another .• Lightning surges flashing over an insulator .• Birds, reptiles, or small animals bridging between an energized

line and a grounded surface .• Tree branches touching energized lines .• Switching surges that flash over an insulator .

Based on statistics and observations, the need for a trip-and-reclose function was readily recognized; that is, if the line could be tripped open momentarily, a subsequent reclosure very likely would be successful because, by then, the cause of the fault would be gone . Thus, the automatic circuit recloser, in providing this trip-and-reclose function, virtually eliminates prolonged outages on distribution systems due to temporary faults or transient overcurrent conditions .

Recloser classifying featuresMajor classifying features of automatic circuit reclosers are: • Single-phase or three-phase• Control: hydraulic or electronic• Interrupters: oil or vacuum• Insulation: oil, air, or epoxy

Table 1 contains a detailed listing of reclosers currently manufactured by Eaton’s Cooper Power Systems .

Recloser: single-phase or three-phaseBoth single- and three-phase reclosers are available to satisfy application requirements .

Single-phase reclosers

Single-phase reclosers, as shown in Figure 1 and 2, are used to protect single-phase lines such as branches or taps of a three-phase feeder . They can also be used on three-phase circuits where the load is predominantly single-phase . Thus, when a permanent phase-to-ground fault occurs, one phase can be locked-out while service is maintained to the remaining two-thirds of the system .

Three-phase reclosersTwo types of three-phase reclosers are available:• Single-Phase tripping• Three-Phase tripping

Single-phase tripping

The triple-single reclosers, shown in Figures 3 and 4, have three modes of operation:• Three-phase trip and three-phase lockout . All three phases

simultaneously trip on an overcurrent, reclose and sequence together .

• Single-phase trip and three-phase lockout . Each phase operates independently for overcurrent tripping and reclosing . If any phase sequences to lockout condition (due to permanent fault), or if “lockout” is locally or remotely asserted, the other two phases trip open and lock out . Thus, extended single-phase energization of three-phase loads is prevented .

• Single-phase trip and single-phase lockout . Each individual phase trips and sequences to lockout independent of each other . This is primarily for residential loads and/or where single-phasing of three-phase loads is protected by other means .

Another configurable option is also available to trip and lockout all three phases in the event of a phase-to-phase or three-phase fault . Should a phase-to-phase or three-phase fault be detected on the system, all three reclosers will trip and lockout whenever any one phase sequences to lockout . Three-phase lockout occurs if a multiple phase fault is present as the recloser advances to lockout .

Three-phase tripping

There are various types of three-phase tripping reclosers available to improve system reliability . The recloser selection is based upon electrical ratings required, interrupting and insulation medium, and the selection of hydraulic or electronic control .• Three-phase trip and three-phase lockout . Larger reclosers such

as the units shown in Figures 5 and 6, use this mode . For any fault—single-phase-to-ground, phase-to-phase, or three-phase—all contacts open simultaneously for each trip operation . The three phases, mechanically linked together for tripping and reclosing, are operated by a common mechanism .

Controls: hydraulic or electronicThe intelligence that enables a recloser to sense overcurrents, select timing operation, time the tripping and reclosing functions, and finally lockout is provided by its control . There are two basic types of control schemes used: an integral hydraulic control or an electronic control located in a separate cabinet .

Hydraulic controls

Hydraulic recloser control is used in most single-phase reclosers and in three-phase recloser types 6H, V6H, W, VW, WV27, VWV27, WV38X, and VWV38X . It is built as an integral part of the recloser . With this type of control, an overcurrent is sensed by a trip coil

that is connected in series with the line .

When the overcurrent flows through the coil, a plunger is drawn into the coil to trip open the recloser contacts . Timing and sequencing are accomplished by pumping oil through separate hydraulic chambers or ducts .

For smaller reclosers, the reclosing energy is provided by springs that are charged by the series trip-coil plunger during overcurrent operation .

Larger reclosers are closed from a separate closing solenoid that is energized by line potential from the source side of the recloser .

Electronic controls

Eaton’s Cooper Power Systems electronic recloser controls are used in most three-phase reclosers and in the single-phase SPEAR recloser control . Compared with the hydraulic control, they are more flexible, more easily customized and programmed, and many have advanced protection, metering, and automation functionality .

The electronic control is housed in a cabinet separate from the recloser and conveniently permits changes to operational settings . A wide range of accessories is available to customize the basic opera-tion, solving many application problems .

Current sensing

Line current is sensed by special sensing current transformers in the recloser . The recloser and control are connected by a multi-conductor control cable that carries sensing transformer secondary currents to the control and the necessary trip and close signals from the control to the recloser .

Microprocessor-based controls

Eaton’s Cooper Power Systems offers numerous electronic controls that can be used in conjunction with its broad line of electronically controlled reclosers .

The Form 6 control, see Figures 7 and 8, provides maximum protective hardware design and simple interactive graphical interfaces for complete user customization . All standard control operating parameters, including minimum trip levels, time-current curve selection, and sequences of recloser operation, are keyboard programmable .

This control utilizes a powerful PC-based interface software to configure control settings, record metering information, and establish communication parameters . It also provides analysis tools that include fault locating, event recording, and oscillography functions .

Interrupting medium: oil or vacuumReclosers use either oil or vacuum as the interrupting medium .

Oil interrupters

Reclosers using oil for current interruption use the same oil for basic insulation . Most reclosers with hydraulic control (except the W-group reclosers) also use the same oil for timing and counting functions .

Vacuum interrupters

Vacuum interrupters provide fast, low-energy arc interruption with long contact and interrupter life, low mechanical stress, and maximum operating safety . With arc interruption taking place in a vacuum, contact and interrupter life far exceeds other interrupting media .

Eaton’s Cooper Power Systems vacuum interrupters (Figure 10) are designed with a metal and ceramic housing for maximum strength and long-term vacuum integrity . The high-alumina ceramic has more than five times the strength of glass, which permits a higher processing temperature to develop maximum purity of the assembly, and is impervious even to helium penetration to sustain the vacuum level .

With over 40 years of experience, Eaton’s Cooper Power Systems is a world leader in the design and manufacture of vacuum interrupters for use in distribution switchgear . A state-of-the-art vacuum interrupter clean room manufacturing facility ensures the production of very high quality interrupters that provide long and trouble-free operating life .

Depending on type, a vacuum recloser may use either oil, air, or epoxy as the insulating medium .

Recloser applicationReclosers can be used anywhere on a distribution system where recloser ratings are adequate for system requirements . Locations for reclosers are:• In substations as the primary feeder protective device .• On distribution lines at a distance from a substation, to

sectionalize long feeders and thus prevent outages of the entire feeder when a permanent fault occurs near the end of the feeder .

• On important taps of main feeders to protect the main feeder from interruptions and outages due to faults on the taps .

Application criteria

To properly apply automatic circuit reclosers, five major factors must be considered:

1 . System voltage . System voltage will be known . The recloser must have a voltage rating equal to—or greater than—system voltage .

Figure 9. SPEAR recloser control.

280-05-6

www.cooperpower.com

2 . Maximum fault current available at the recloser location . Maximum fault current will be known or can be calculated . The recloser interrupting must be equal to—or greater than—the maximum available fault current at the recloser location .

3 . Maximum load current . The recloser continuous current rating must be equal to—or greater than—anticipated circuit load . For series-coil-type reclosers, the coil size can be selected to match the present load current, the anticipated future load current, or the substation transformer capacity . Minimum-trip current is nominally twice the coil continuous-current rating .

4 . For electronically controlled reclosers, minimum-trip current must be greater than any anticipated peak load . Generally, a trip-cur-rent value of at least twice the expected load current is used .

5 . Minimum-fault current within the zone to be protected . Minimum fault current that might occur at the end of the line section must be checked to confirm that the recloser will sense and interrupt this current .

6 . Coordination with other protective devices on both the source and the load sides of the recloser .

Coordination with other devices

After the first four application factors have been satisfied, coordination of the recloser with both the source- and the load-side devices must be determined . Proper selection of time delays and sequences is vital to assure that any momentary interruption or longer-term outage due to faults is restricted to the smallest possible section of the system .

Generally, recloser timing and sequences are selected to coordinate with the source-side devices . After the size and sequence of the required recloser has been determined, the protective equipment

farther down the line is selected to coordinate with it as shown in Figure 11 .

Dual timing

Automatic circuit reclosers have dual-timing capabilities; that is, the first fault-current interruptions (one or more) are performed in accordance with a fast or instantaneous timing characteristic (no intentional time delay) and the remaining interruptions are performed in accordance with a predetermined time delay .

The first operations are as fast as possible in order to clear temporary faults before any line damage can occur . If the fault is permanent, the time-delay operation allows the down-line device—either another recloser or a fuse—to clear first .

Recloser-to-recloser coordination is achieved primarily by selecting different coil sizes or trip values with further coordination possible by different time delays or sequences . To coordinate a recloser with a downline fuse, the fuse link size should be selected to coordinate with the recloser fast and time-delay curves .

Figure 12 shows a typical recloser operating sequence-to-lockout for a permanent fault .

A recloser operating on its fast curve should clear a temporary fault before the fuse link can be damaged . When on its time-delay curve, a recloser operation should be more delayed than the fuse-link clearing time, allowing the fuse to clear permanent faults without tripping the recloser .

General ratings information and catalog guide for single- and three-phase reclosers

Eaton’s Cooper Power Systems Business2300 Badger DriveWaukesha, WI 53188United StatesCooperpower.com

280-05-16

DescriptionTypes E, 4E, V4E, H, 4H, V4H, L, and V4L single-phase reclosers and Types 6H and V6H three-phase reclosers provide reliable, self-contained distribution-circuit overcurrent protection at low initial cost, and require minimal service. Because most line faults are temporary in nature, they will clear after only momentary circuit interruption; therefore, permanent outages usually are prevented. Automatic circuit reclosers both improve customer service and reduce operating costs.

A summary of all available reclosers – ratings, basic characteristics, and applications – is included in Catalog 280-05, General Ratings Information and Catalog Guide for Single-Phase and Three-Phase Reclosers.

Basic ratings and characteristic featuresReclosers in the E, H, and L groups include most of the single-phase reclosers produced by Eaton's Cooper Power Systems. The three-phase reclosers – Types 6H and V6H – are included in here because they adapt three single-phase interrupting structures with a common lockout mechanism. In operation, these reclosers sense line current in each phase individually and trip individually; however, if one phase sequences to lockout, all phases lock out.

Reclosers can be installed on poles or in substations to protect lines requiring the ratings shown in Table 1.

Both single-phase and three-phase reclosers are hydraulically controlled. Tripping is initiated by a series-connected coil. Current-carrying and interrupting capacities vary with the operating coil’s rating, which is selected to meet circuit requirements. A choice of dual time-current characteristics permits coordination with other protective devices. A non-reclosing feature (Figure 1), standard on all Eaton's Cooper Power Systems reclosers, is set with a hookstick-operated lever for one operation to lockout without removing the recloser from service.

Two types of interrupters are available:

1. In Types E, 4E, 4H, L, and 6H reclosers, current interruption takes place in oil.

2. Types V4H, V4L, V4E, and V6H reclosers are equipped with vacuum interrupters. A major advantage of vacuum interrupters is reduced maintenance frequency.

280-10-1

Technical Data 280-10Effective May 2014Supersedes June 1999

ApplicationBoth single- and three-phase H-group and L-group reclosers are designed, tested, and rated for operation on 14.4 kV three-phase systems where the line-to-ground voltage is 8.32 kV. Bushing insulation strength and other line-to-ground insulation is designed for this 8.32 kV stress.

The standard recloser (110 kV BIL) is not suitable for operation on single-phase taps of 14.4/24.9 kV systems. Operation on these higher voltage systems will stress the insulation at the 14.4 kV level, resulting in excessive radio influence voltage and deterioration of the insulation.

Types E, 4E, and V4E reclosers can be used for operation on single-phase taps of a 20/34.5 kV system where the 150 kV BIL rating is satisfactory. The bushings and other line-to-ground insulation are adequate for the 20 kV line-to-ground voltage stress. Since the interrupting capability is 24.9 kV, application on this system is limited to single-phase taps only. Operation on the three-phase line can result in a single recloser attempting to interrupt the full 34.5 kV voltage, which is in excess of its rating.

Surge protectionReclosers operate best when protected with surge arresters. On line applications, arrester protection is recommended on both sides of the recloser. If protection is to be provided on one side only, install the arrester on the source side. In substations, arresters are located on the load-side. Eaton's Cooper Power Systems distribution-class arresters provide excellent protection; see Catalog 235-99, UltraSIL™ Polymer-Housed Evolution™ Surge Arrester or Catalog 235-35, UltraSIL Polymer-Housed VariSTAR™ Surge Arrester for more information.

Ordering informationTo order an E-, H-, or L-group recloser:

1. Use the chart below to construct a cata!og number that describes the required recloser.

2. From Tables 2 through 13, specify the catalog number that describe the required recloser accessories and mounting equipment.

Constructing a catalog number

To order a basic Type 4H recloser with a l00-amp coil, time-current Curve B, and two fast and two retarded operations to lockout, the catalog number would be constructed as shown on following page.

Figure 1. The non-reclosing feature is set with a handle under the sleet hood (see arrow). When the handle Is down (top), the recloser will trip on overcurrent and lock out without reclosing. When the handle is up (bottom), the recloser will operate according to its internally set program.

Features and detailed descriptionConstruction features

Basic features

E-, H-, and L-group reclosers are designed for long service life with minimum maintenance. Figure 2 describes the parts of the single-phase reclosers.

Heads are aluminum castings. Heavy-gage steel tanks are finished with an inhibiting epoxy prime coat and finish-coated with thermosetting acrylic paint. Finish color is light gray. Munsell 5BG 7.0/0.4.

A Buna-N o-ring gasket assures an oil-tight seal between head and tank. The gasket is confined in a groove, providing controlled compression.

Insulating supports connect the hydraulic mechanism to the head. Made of filament-wound glass epoxy, these supports provide high

mechanical and dielectric strength and moisture resistance.

With the exception of Types V4E, V4H, V4L, and V6H, all reclosers described here have oil interrupters; Types V4E, V4H, V4L, and V6H are equipped with vacuum interrupters. Kits are available for field conversion of 4H and 6H reclosers from oil to vacuum interruption. Type L reclosers cannot be converted from oil to vacuum interruption.

Mechanisms have been thoroughly field-proven through many years of service. They are designed and built in accordance with ANSI® Standard C37.60.

For more detailed information on construction of H-group reclosers, ask for Reference Data R280-10-1; for E-group and Type L reclosers, specify R280-10-2.

Interrupter and contact construction

Oil interrupter

Contacts – silverplated copper-tungsten alloy to resist arc erosion – are arranged to give two breaks in series. Different interrupter and contact configurations are employed in the various recloser types but all oil interrupters are designed to provide fast arc extinction and self-cleaning of the contacts through a wiping action. Type H reclosers feature a wiping contact design; Types 4H, 6H, E, 4E, and L employ a bayonet contact design.

Vacuum interrupter

Arc interruption in Types V4H, V4L, V4E, and V6H reclosers is fast – arcing time is generally less than 1/2 cycle. Arc energy is low, minimizing mechanical stress. Also, contact erosion is substantially reduced, contributing to long service life without contact maintenance.

Unaffected by ambient temperature, contaminants, humidity, or altitude, vacuum interruption provides maximum reliability. Because there are no arcing by-products to contaminate the insulating oil, inspections are fewer and maintenance costs are lower.

The vacuum interrupter is fully interchangeable with the oil interrupter used in Type 4H and 6H reclosers. A replacement assembly is available for quick field installation.

Basic operationEaton's Cooper Power Systems E-, H-, and L-group reclosers are series-trip-solenoid-operated and hydraulically controlled. Series tripping provides simple and reliable operation since the tripping energy is taken directly from the fault itself. During tripping, the mechanism stores energy for reclosing. Hydraulic control permits accurate coordination with other protective equipment.

The two three-phase reclosers in the H group – Types 6H and V6H – consist of three single-phase reclosers in one tank (Figure 3), mechanically interlocked for lockout operation. This permits initial independent operation of a single phase in the event of a fault on any one phase. Should the fault persist after the initial operation and the phase proceed to lockout, the mechanical interconnection opens and locks out the other two phases as well. A separate counter on each phase accumulates information for operating records.

For more detailed information on operation of H-group reclosers, ask for Reference Data R280-10-1; for E-group and L-group reclosers, specify R280-10-2.

Non-reclosing operation

All E-, H-, and L-group reclosers are equipped with a non-reclosing feature. Simply by moving an externally operable handle with a hookstick, the recloser can be set for one operation to lockout. The non-reclosing feature is a valuable tool when hot-line work is necessary. Should an overcurrent occur while the non-reclosing feature is activated, the recloser will trip according to the first time/current curve programmed in its operating sequence and then lock out. When the feature is deactivated, the recloser will operate normally according to the internally programmed sequence.

Series-trip solenoid

Fault-current sensing is provided by a series-connected solenoid coil that carries line current. When a fault occurs, tripping is initiated by the solenoid plunger.

The plunger, normally held at rest by the closing springs, is drawn into the coil by the magnetic force generated by the fault current. Downward travel of the plunger overtoggles springs in the contact assembly that open the recloser contacts. The same motion charges the closing springs in preparation for a reclosing operation.

When the circuit is opened, the solenoid coil is deenergized, allowing the closing springs to close the contacts and simultaneously return the plunger to its original position.

Figure 3. Untanked view of typical three-phase recloser (Type 6H shown).

280-10-6

www.cooperpower.com

Contact operating speeds – controlled entirely by the springs – are independent of the magnitude of the fault current. Total time to contact opening is proportional to the level of fault current passing through the series-trip solenoid.

When the recloser operates to lockout, the hydraulic mechanism releases a lock-out spring and mechanism, preventing the plunger from returning and the contacts from reclosing.

The series-trip coil is capable of withstanding forces caused by maximum-rated fault currents and is effectively shunted with a bypass gap for surge protection.

Hydraulic control mechanism

The hydraulic control mechanism provides selectivity in timing enabling flexibility in application and coordination with other equipment. All timing is governed by the hydraulic mechanism which:

1. controls the timing before contact opening;

2. establishes the time delay before the contacts reclose;

3. counts the number of operations;

4. causes the recloser to lock out when the preset number of trip operations has been completed.

Variations of timing characteristics and sequences can be programmed for a maximum of four operations. When a recloser is programmed for both fast and retarded operations, the fast operations – involving no intentional time delay – occur first in the sequence according to the recloser’s A curve time-current characteristic. Retarded operations are according to the recloser’s B or C time-current curve (B, C, or D curve for Types E, 4E, and L). See Time Current Curves R280-91-10 for Type E reclosers; R280-91-8 for Type 4E; R280-91-1 for Type H; R280-91-2 for Types 4H, V4H, 6H, and V6H; R280-91-3 for Type L; and R280-91-15 for Types V4L and V4E.

Basic ratingsType D reclosers protect systems rated 2.4 through 14.4 kV and Type DV reclosers protect systems rated through 34.5 kV. Table 1 summarizes the ratings of the Types D and DV reclosers. For basic ratings and application information for all reclosers from Eaton’s Cooper Power Systems, see Technical Data 280-05, General Ratings Information and Catalog Guide for Single-Phase and Three-Phase Reclosers.

Basic characteristicsTypes D and DV reclosers are hydraulically controlled protective devices in which tripping is initiated by a series-trip coil that releases the stored-energy trip mechanism when an overcurrent occurs. Current carrying and interrupting capacities depend on the current rating of the series trip coil. Minimum-trip current is 200% of the coil rating except X coil ratings which initiate tripping at 140%. A closing solenoid supplies the energy for contact closing and also stores energy in the trip mechanism. High-voltage closing solenoids are connected to the system on the source-side of the recloser. Solenoid voltage rating is based on the system operating voltage. Low-voltage closing solenoids can be used if auxiliary voltage is supplied to the recloser. Dual time-current characteristics permit coordinating Types D and DV reclosers with other protective devices on a distribution system. Fast-curve operations are followed by trip operations on a delayed curve. A choice of four delayed characteristics allows flexibility in system coordination.

Oil interruptionTypes D and DV reclosers use oil as the arc-interrupting medium. Movable bridge-type contacts provide two breaks in series. Separate self-generating interrupter chambers at each of the two breaks effectively interrupt all current from minimum load to rated maximum fault.

Surge protectionBest operating results are achieved if reclosers are protected with surge arresters. On line applications, arrester protection is recommended on both sides of the recloser. (If protection is on one side only, it should be on the source-side.) In substations, arresters should be on the load-side. Arresters provide excellent protection and are available with mounting brackets to fit Eaton’s Cooper Power Systems reclosers; see Technical Data 235-99, UltraSIL™ Polymer-Housed Evolution™ Surge Arrester or Technical Data 235-35, UltraSIL Polymer-Housed VariSTAR™ Surge Arrester for information.

Basic recloser designEaton’s Cooper Power Systems Types D and DV hydraulically controlled, single-phase reclosers (Figures 1 and 2) are designed to protect circuits on systems operating through 34.5 kV. With the ratings available and the ability of these reclosers to coordinate with other protective devices – including lower-rated reclosers – they can be applied in a variety of protection schemes.

Closing energy is supplied by a closing solenoid which simultaneously charges the opening springs in preparation for a tripping operation. Fault currents are sensed by a trip solenoid (connected in series with the recloser contacts) that initiates the tripping operation by releasing the opening springs.

Series tripping provides simple and reliable operation since the energy to initiate the tripping operation is taken directly from the line. Types D and DV reclosers are self-contained; i.e., they require no external control or control power source.

The hydraulic control incorporates separate elements to govern time delay operations and regulate the number of operations to lockout. The basic design of the Types D and DV reclosers has been proven by more than 30 years of field service.

ConstructionLike all the other reclosers from Eaton’s Cooper Power Systems, Types D and DV reclosers are designed for long service with little maintenance. Heads are aluminum castings and the tanks are constructed of heavy-gage steel. The tanks are treated with a corrosion inhibiting epoxy primer, followed by a finish coat of thermosetting acrylic paint. A Buna N o-ring gasket is confined in a groove in the head casting to assure an oil-tight seal between the head and the tank.

The entire internal mechanism is suspended from the head casting so that the mechanism and the head assembly can be removed from the tank as a unit to simplify servicing. The head casting can be rotated with respect to the tank, in 60-degree increments, for optimum positioning of bushing terminals and manual operating handles. The insulating supports from which the interrupter and internal mechanism are suspended are constructed of filament wound glass epoxy for high electrical and mechanical strength and moisture resistance.

Figure 2. Untanked view of Type D recloser (shown with head casting removed). Construction of Type DV is similar.

Series-trip solenoidSensing of fault currents in Types D and DV reclosers is provided by a trip solenoid which is connected in series with the recloser contacts and can carry line current up to its rating. Continuous current and minimum-trip values can be changed by replacing the coil. Coils used in Types D and DV reclosers are interchangeable (see Table 2).

When fault current flows in excess of the minimum trip rating, the trip solenoid plunger – normally held at rest by the mechanism – is drawn into the coil by the magnetic effect generated by the fault current. Near the end of the downward stroke, a linkage connected to the solenoid plunger trips a latch which releases the charged opening springs and the recloser contacts are opened. The series-trip coil is effectively surge-protected by a shunting bypass gap on reclosers with trip coils rated below 100 amps.

Closing SolenoidClosing energy – as well as the energy to charge the opening springs – is supplied by a high-voltage closing solenoid Figures 3 and 4) connected phase-to-ground on the source-side of the Type D and DV recloser.

The aluminum cover casting is marked to designate bushings to aid in making the proper connections. The grounded side of the solenoid is connected to a connector on the cover. The phase-to-ground connection permits Types D and DV reclosers to function independently of outside control power, although application is limited to multigrounded-wye systems. A low-voltage closing solenoid, energized by an auxiliary ac or dc low-voltage source, is also available, permitting application of Types D and DV reclosers on other than grounded-neutral systems.

When the recloser contacts are closed, the solenoid closing plunger is latched in the down position. This latch is tripped simultaneously with the release of the opening springs and as the solenoid plunger moves upward. A timing orifice in the bottom of the solenoid-plunger cylinder regulates the rate at which upward movement can take place as oil is drawn into the cylinder.

As the solenoid plunger reaches the top of its stroke, the high-voltage line contactor energizes the closing solenoid, pulling the plunger down. The closing solenoid contactor opens de-energizing the coil and through the mechanical linkage, the main contact-operating rods are simultaneously moved upward to close the contacts. At the same time, the opening springs are charged in preparation for a tripping operation.

Hydraulic control system operationThe number and sequence of operations to lockout and time-delay operations of Types D and DV reclosers are controlled by two separate, sealed hydraulic mechanisms which are mechanically linked. These sealed units contain HFA hydraulic fluid and have extremely consistent and accurate operating characteristics.

Hydraulic integrator − pump and lockout piston assembly

The hydraulic integrator (Figure 5) containing the hydraulic pump and lockout piston, regulates the number of fast and delayed trip operations, counts the operations to lockout, and initiates lockout after a preset number of operations. The hydraulic pump (Figure 5) is linked to the closing-solenoid plunger and is pushed downward with each return operation of the plunger. With its downward stroke, the pump forces a measured amount of fluid under the lockout piston (Figure 5), causing it to rise one step. Ball-type check valves retain the charge. When the closing coil is energized, the recloser contacts close and the pump returns to its normal position.

The integrator mechanism is linked to the time-delay unit through the cam shown in Figure 6. Upward movement of the lockout piston causes the cam to rotate counterclockwise. After the number of fast operations preset on the cam, it has advanced to engage the roller mechanism located at left of the cam. This brings the time-delay unit into operation. When the lockout piston reaches the top of its stroke, it trips the lockout latch through another set of linkages, and a spring locks out the recloser contacts.

On the lockout operation, the resetting lever (Figure 5) raises the plunger to which it is linked. This releases the ball check-valve beneath the plunger, hydraulic fluid is withdrawn from beneath the lockout piston, and it quickly resets. After the recloser is reset from lockout, it is ready for another full sequence of operations.

For temporary faults that are cleared before the recloser mechanism reaches lockout, the lockout piston resettles through a combination of spring action and fluid bleeding past the piston to reset the integrator mechanism.

Figure 5. Cutaway view of hydraulic integrator.

Figure 6. Hydraulic integrator and time-delay linkage.

Operating settingsThe required sequence of fast and delayed operations and the required number of operations to lockout are factory set per customer specification. Either or both settings are easily changed in the field; only partial untanking of the recloser is necessary and no special tools are needed. Internal settings for the number of operations to lockout permit the recloser to be programmed for two, three, or four trip operations before lockout. To set the number of operations to lockout, the lockout lever (Figure 6) is indexed to one of three holes in its assembly, corresponding to the number of desired operations.

The number of fast operations in the sequence is established by indexing the sequence selector cam shown in Figure 6. The cam is simply rotated until the desired number of fast operations appears opposite an arrow above the cam. An indent holds the cam in the selected position.

Setting the number of fast operations determines the number of delayed operations in the sequence to lockout; for example, if four operations to lockout have been selected and the cam has been adjusted for two fast operations, the sequence will be two fast, followed by two delayed operations.

Programming for one operation to lockout is done with the external non-reclosing handle, located under the sleet hood. Moving the external non-reclosing handle down activates the non-reclosing feature (one operation to lockout). This overrides the internal setting, but does not change it physically. When the non-reclosing feature is deactivated (handle moved up), the number of operations to lockout automatically reverts to the internal setting, providing complete flexibility for testing or service without disturbing the programmed operations-to-lockout setting.

Time-delay mechanismDelayed operations of the Types D and DV reclosers are established by the hydraulic time-delay mechanism which engages the series trip-solenoid linkage after the preset number of fast operations. The time-delay mechanism impedes the downward stroke of the series trip-solenoid linkage to provide the desired delayed time-current characteristic. The selected curve is established by the amount of engagement during the downward stroke of the time-delay mechanism. For a B or D curve, approximately half of the stroke is unimpeded; then the trip solenoid linkage engages the time-delay mechanism, impedes the remainder of the stroke and establishes the desired curve. With slower C or E curves, the amount of engagement is increased.

The time-delay mechanism offers a choice of two characteristics: B and C, or D and E. The desired combination must be specified since one unit does not provide all four characteristics. Adjustment from one characteristic to the other is made by indexing a thumbscrew and bracket arrangement on the time-delay unit. This changes the curve by changing the amount of engagement (Figure 7).

Establishing delayed operationsOperation of the time-delay mechanism is initiated by the hydraulic integrator. As sequence selector cam (Figure 6) is rotated counterclockwise by the upward movement of the lockout piston, it engages the roller assembly causing the solenoid linkage engagement arm to pivot clockwise, placing its hook above the pin on the time-delay arm. When a delayed tripping operation occurs and the engagement arm moves downward with the trip-solenoid linkage, its hook engages a pin on the time-delay arm and the time-delay mechanism impedes the remainder of the stroke (Figure 7).

Figure 7. Changing time-current characteristic to the alternate curve is accomplished by loosening the thumbscrew and indexing the pin on the time-delay unit to the bracket hole for the alternate curve.

OperationThe hydraulic time-delay mechanism piston (Figure 8) is pulled downward by the trip-solenoid linkage. A floating plate (retained by an open basket) at the bottom of the hollow piston functions as a one-way valve on the downstroke, sealing the bottom of the piston.

On low-current operations, displaced oil is forced around the greased pin of the low-current timing valve and is allowed to return to the space above the piston. When a higher current fault is experienced, increased oil pressure raises the spring-loaded valve so that oil flows through both valves and the tripping operation is accelerated proportionately. The hydraulic time-delay mechanism has no effect on contact-opening speed – it only delays the moment at which the opening springs are released.

Oil interrupter constructionFast arc interruption (down to 2.7 cycles clearing) is achieved by bridge-type contacts that provide two current breaks in series. The bayonet-type moving contacts are silver-plated tungsten alloy for erosion resistance and good conductance.

The stationary contact assemblies are tulip-type clusters of silver-plated contact fingers held together by garter springs. The contacts are self-cleaned by the opening and closing wiping action.

Each current break is provided with a self-generating-type arc interrupter structure (Figure 9) which includes a series of vented chambers. As the contacts open, the arc generates gap pressure in the upper chamber which blasts oil across the arc and out through the vents. As a result, arc extinction is fast and arc energy levels do not increase as fast at the higher fault-current levels.

Mounting equipmentTypes D and DV reclosers are furnished with two sets of mounting adapter plates for pole or substation mounting. For direct pole mounting, the curved plates are installed between the pole and the mounting brackets of the recloser. For mounting on a substation truss or pole-mounted channel, add the flat adapter plates between the curved plates and the mounting surface. An accessory cluster-type frame for mounting three Type D reclosers is also available. See Table 5 on page 3 for ordering information.

Types W, WV27, WV38X, VW, VWV27, and VWV38X, three-phase hydraulically controlled reclosers

W-group three-phase automatic, circuit reclosers from Eaton's Cooper Power Systems provide reliable, economical overcurrent protection for distribution circuits rated through 38 kV. Compact and self-contained in operations, these reclosers can be easily installed on poles and in substations. Employing the service-proven hydraulic control, the W-group reclosers can be readily coordinated with circuit breakers, sectionalizers, fuses, and other reclosers on the distribution system.

Eaton's Cooper Power Systems reclosers in a distribution system protection scheme offer significant user advantages. Their broad application capabilities permit the user to select exactly the right recloser for the protection required. When needed, application expertise, backed by worldwide recloser application experience, is readily available. Knowledgeable design capability, based on over 60 solid years of recloser manufacturing experience, is the backbone of our dependable reclosers. Progressive development programs using the latest technologies have resulted in the modern, efficient reclosers from Eaton's Cooper Power Systems.

W-group reclosers, like all reclosers from Eaton's Cooper Power Systems, are designed and built in accordance with ANSI C37.60.

Six distinct types – W, WV27, WV38X, VW, VWV27, and VWV38X – within the W-group offer a broad range of voltage, continuous current, and interrupting ratings. Accessories permit tailoring a recloser to specific application requirements. Mounting equipment for both pole and substation facilitates installing a recloser precisely where system requirements demand its protection.

Basic ratingsW and VW reclosers protect systems rated 2.4 through 14.4 kV; WV27 and VWV27 reclosers protect systems rated through 24.9 kV; and WV38X and VWV38X reclosers protect systems rated through 34.5 kV. Table 1 summarizes the ratings of the W-group reclosers. For basic ratings and application information for all reclosers from Eaton's Cooper Power Systems, see Catalog Section 280-05.

Technical Data 280-30Effective July 2014Supersedes May 2003

Basic characteristicsW-group reclosers are hydraulically controlled protective devices in which tripping is initiated by a series trip coil that releases the stored-energy trip mechanism when an overcurrent occurs. Current-carrying and interrupting capacities depend on the rating of the recloser series trip coil. Minimum-trip current is 200% of the coil rating, except X coil ratings which initiate tripping at approximately 140%.

A closing solenoid supplies the energy for contact closing and also stores energy in the trip mechanism. High-voltage closing solenoids are connected to the system on the source side of the recloser. Solenoid phase-to-phase voltage rating is based on the system operating voltage. Low-voltage closing solenoids can be used if auxiliary voltage is supplied to the recloser.

Dual time–current characteristics permit coordinating W-group reclosers with other protective devices on a distribution system. Fast-curve trip operations are followed by trip operations on a delayed curve. A choice of four delayed characteristics allows flexibility in system coordination. Ground tripping is available as an accessory. A variety of operating, indicating, and service accessories extends a W-group recloser’s normal flexibility even further.

Oil interruption

W, WV27, and WV38X reclosers use oil as the arc-interrupting medium. Movable bridge-type contacts provide two breaks in series on each phase. Separate self-generating interrupter chambers at each of the two breaks effectively interrupt all currents from minimum load to rated maximum fault.

Vacuum interruption

VW, VWV27, and VWV38X reclosers use vacuum as the arc-interrupting medium. Vacuum interruption not only means long contact life, it also offers considerably longer duty cycles than oil interruption. A single break on each phase is accomplished by separating contacts inside the vacuum interrupter. All arcing is contained within the vacuum envelope. Low-energy arc interruption in a vacuum results in far less shock and demonstration than interruption in oil, thus extending the vacuum recloser mechanism life. Because interruption within the vacuum envelope does not add contaminants to the insulating oil, recloser maintenance is minimized and intervals between oil changes can generally be extended.

Surge protection

Best operating results are achieved if reclosers are protected with surge arresters. On line applications, arrester protection is recommended on both sides of the recloser. (If protection is on one side only, it should be on the source-side.) In substations, arresters should be on the load-side. Eaton's Cooper Power Systems distribution-class arresters provide excellent protection and are available with mounting brackets to fit reclosers from Eaton's Cooper Power Systems; see Service Information S280-85-7, KA126H3 and KA847W Surge Arrester Mounting Brackets Assembly and Installation Instructions.

Features and detailed descriptionBasic recloser design

Eaton's Cooper Power Systems three-phase W-group reclosers are designed to protect circuits on systems operating through 34.5 kV. With the ratings available and the ability of these reclosers to coordinate with other protective equipment, including lower-rated reclosers, they can be applied in a variety of schemes.

The range of protection can be extended by a ground-trip accessory, which provides protection against ground-fault currents that are less than the minimum-trip value of the series coils. Flexibility of application is greatly enhanced by accessories that enable remote control of the recloser.

Closing energy is supplied by a closing solenoid that simultaneously charges the opening springs in preparation for a tripping operation. Fault currents are sensed by trip coils (connected in series with the recloser contacts) that initiate the tripping operation by releasing the opening springs.

Series tripping provides simple and reliable operation because the energy to initiate the tripping operation is taken directly from the line. W-group reclosers are self-contained: they require no external control or control power source.

The hydraulic control incorporates separate elements to govern time-delay operations and regulate the number of operations to lockout. The W-group basic design has been proven by more than 50 years of field service.

Construction

Like all the other reclosers from Eaton's Cooper Power Systems, the W-group reclosers are designed for long service life with little maintenance. Heads are aluminum castings. Tanks are heavy-gage steel, finished with light gray polyester powder paint (ASA70). An o-ring gasket confined in a groove, for controlled compression, assures an oil-tight seal between the head and the tank. A 1/2-inch brass oil-sampling and drain valve near the bottom of the tank is standard.

The entire internal mechanism is suspended from the head casting so that the mechanism and the head assembly can be removed from the tank as a unit. Reclosers are mounted by brackets that can be attached to the head casting. This permits easy access to the contacts and the mechanism in the field by lowering the tank with a wire-rope winch, which is available as an accessory.

The insulating supports from which the three interrupters are suspended are filament-wound glass epoxy for high electrical and mechanical strength and moisture resistance.

Operation

Series trip coil

Fault current in the W-group is sensed by the three trip coils that are connected in series with the recloser contacts and can carry line current up to their rating. Coils of applicable ratings are interchangeable among the W-group reclosers. Continuous current and minimum trip ratings can be changed by replacing the coils.

When fault current in excess of the minimum trip ratings flows on one or more phases, the trip solenoid plunger, which is normally held at rest by the mechanism, is drawn into the coil by the magnetic effect generated by the fault current.

Near the end of the downward stroke, a linkage connected to the trip plunger trips a latch that releases the charged opening springs and the recloser contacts are opened.

The series trip coil is surge-protected by a shunting bypass gap on reclosers with trip coils rated below 100 A.

Independent fault detection on each phase is provided by separate trip coils. A common bar trips all three phases, preventing single-phase supply to three-phase loads. A trip coil carrying a higher fault current will override and cause faster tripping than a phase experiencing a lower fault current.

Closing solenoid

Closing energy – as well as the energy to charge the opening springs in the W-group reclosers – is supplied by a high-voltage closing solenoid, which is connected phase-to-phase and energized through a contactor. When the recloser contacts are closed, the solenoid plunger is latched in the down position. This latch is tripped simultaneously with the release of the opening springs and the solenoid plunger moves upward. A timing orifice in the bottom of the solenoid-plunger cylinder regulates the rate at which upward movement can take place as oil is drawn into the cylinder.

As the solenoid plunger reaches the top of its stroke, the high-voltage line contactor energizes the closing solenoid, pulling the plunger down. The closing solenoid contactor opens, de-energizing the coil, and, through the mechanical linkage, the main contact-operating rods are simultaneously moved upward to close the contacts. At the same time, the opening springs are charged in preparation for a tripping operation.

W, WV27, VW, and VWV27 reclosers – which are rated through 24.9 kV – are equipped with a high-voltage closing solenoid contactor with two breaks in series. The higher rated reclosers – WV38X and VWV38X – are equipped with a contactor with four breaks in series.

Control of the upward travel of the plunger regulates reclosing time. Normal reclosing time for the W-group reclosers is two seconds. The first reclosing operation in the programmed sequence can be 30 or 45 cycles when the dual-reclosing accessory is used.

Hydraulic control system operation

The number and sequence of operations to lockout and the time-delay operations are controlled by two separate hydraulic mechanisms which are mechanically linked.

Pump-and-Lockout-Piston assembly

The hydraulic pump, associated cam, and linkages regulate the number of fast and delayed operations, count the operations to lockout, and, after a preset number of operations, initiate lockout.

The hydraulic pump (Figure 5) is linked to the closing solenoid plunger and pushed downward with each return operation of the plunger. With its downward stroke, the pump forces a measured amount of fluid under the lockout piston, causing it to rise one step. Ball-type check valves retain the charge. When the closing solenoid is energized, the recloser contacts close and the pump returns to its normal position.

The lockout piston is linked to the sequence selector cam (Figure 6) and the lockout bar. Upward movement of the lockout piston causes the cam to rotate counterclockwise and the lockout bar to advance one step. The number of fast operations are preset on the cam.

After these operations, the cam edge engages the roller and pushes it to the right. A mechanism arm attached to the roller engages the time-delay mechanism on each phase. Subsequent operations are then delayed.

When the lockout bar completes its travel, it trips the lockout latch through another set of linkages and springs lock the recloser contacts open. The reset rod and valve (Figure 5) are raised, releasing hydraulic fluid from beneath the lockout piston so that it resets quickly. The entire pump and sequencing mechanism are now ready for the next full sequence of operations.

For temporary faults that are cleared before the recloser mechanism reaches lockout, the lockout piston resettles gradually (at a rate of approximately 90 seconds per operation at 25 °C) to reset the recloser mechanism.

Figure 6. Recloser operating sequence is determined by the number of fast operations programmed on the sequence selector cam. The number of delayed operations will be the balance of operations to lockout. The setting on the sequence selector cam is easily changed in the field.

Hydraulic PumpActs as an accurate trip counter by pumping measured amount of oil under lockout piston.

Lockout PistonAdvances toward its lockout position with each recloser trip.

Quick-Release Rod and ValveDumps oil from under lockout piston after lockout so recloser can immediately reset to begin another fault tripping sequence.

Operating settings

The required sequence of fast and delayed operations and the required number of operations to lockout are factory set per customer specification. Either or both settings are easily changed in the field; only a partial untanking of the recloser is necessary and no special tools are needed.

Internal settings for the number of operations to lockout permit the recloser to be programmed for two, three, or four trip operations to lockout. Programming for one operation to lockout is done with the external non-reclosing handle located under the sleet hood. The internal setting is easily changed by moving the horizontal lockout bar (Figure 7) to index the lockout-setting pin in the required notch.

Moving the external non-reclosing handle down activates the non-reclosing feature (one operation to lockout); this overrides the internal setting but does not change it physically. When the non-reclosing feature is deactivated (handle moved up), the number of operations to lockout automatically reverts to the internal setting, providing complete flexibility for testing or service without disturbing the programmed operations-to-lockout setting.

The timing of recloser trip operations can be fast (which includes no intentional time delay), delayed (which follows one of four slower time–current characteristics), or a sequence of fast followed by delayed.

The recloser mechanism is programmed simply by setting the number of fast operations required in each sequence of operations to lockout, by indexing a notched cam to the required number (Figure 6).

It is easily changed by lifting the flat spring tab away from the cam and rotating the cam until the desired number of fast operations is indicated. The setting for the number of fast operations determines the number of delayed operations in the sequence; for example, if four operations to lockout are selected and the cam is adjusted for two fast operations, the sequence will be two fast operations followed by two delayed.

Time-delay mechanism

Delayed operations in W-group reclosers are established by the hydraulic time-delay mechanism on each phase. The time-delay mechanism is engaged with time–current characteristic. The selected curve is established by the time of engagement of the time-delay mechanism. For the B and D curves, approximately half of the stroke is unimpeded, then the trip coil linkage engages the time-delay mechanism and the remainder of the stroke is impeded, establishing the desired curve. With the slower (C and E) curves, the time of engagement is earlier.

The time-delay mechanism permits a choice of two characteristics: B and C or D and E. The time-delay curves will be set at the factory as specified. Adjustment from one characteristic to the other is made by indexing a thumbscrew-and-bracket arrangement on the time-delay mechanism to change the curve by changing the time of engagement (Figure 8).

Established delay operations

Operation of the time-delay mechanism is initiated by the integrating mechanism. As the indexing cam (Figure 6) is rotated counterclockwise by the upward movement of the lockout piston, it engages a roller assembly, causing the solenoid linkage engagement arm to pivot clockwise, placing its hook above the pin on the time-delay arm. When an overcurrent occurs and the engagement arm moves downward with the trip coil linkage, the hook engages the pin on the time-delay arm and the time-delay mechanism impedes the remainder of the stroke.

Operation

The hydraulic time-delay mechanism piston is pulled downward by the trip coil linkage. A floating plate (retained by an open basket) at the bottom of the hollow piston functions as a one-way valve on the downstroke, sealing the bottom of the piston.

On low-current operations, displaced oil is forced around the grooved pin in the low-current valve and is allowed to return to the space above the piston. When a higher current fault is interrupted, increased oil pressure raises the springloaded valve so that oil flows through both valves and the tripping operation is accelerated proportionately.

The hydraulic time-delay mechanism has no effect on contact-opening speed – it only delays the moment at which the opening springs are released.

Figure 7. The internal setting for the number of operations to lockout (two, three, or four) is achieved by positioning the lock-out-setting pin in one of three notches in the lockout bar. This setting is easily changed in the field.

Interrupter construction

Oil interrupters

Fast arc interruption (down to 2-1/2 cycles clearing) is achieved by bridge-type contacts that provide two current breaks in series per phase. The bayonet-type moving contacts are silver-plated tungsten alloy for erosion resistance and good conductance. The stationary contact assemblies are tulip-type clusters of silver-plated contact fingers held together by garter springs. The contacts are self-cleaned by the opening and closing wiping action.

Each current break is provided with a self-generating arc interrupter structure which includes a series of vented chambers. As the contacts open, the arc generates gas pressure in the upper chamber that blasts oil across the arc and out through the vents. As a result, arc extinction is fast and arc energy levels do not increase as fast at the higher fault-current levels.

Vacuum interrupters

Vacuum interrupters provide fast, low-energy arc interruption with long contact and interrupter life, low mechanical stress, and maximum operating safety. With arc interruption taking place in a vacuum, contact and interrupter life are several times greater than with interruption in oil, and interrupter maintenance is virtually eliminated. Because of the shorter contact stroke, mechanical stress and wear on the mechanism is substantially reduced.

Vacuum interrupters are designed with a metal and ceramic housing for maximum strength and long-term vacuum integrity. The high-alumina ceramic has more than five times the strength of glass, permits a higher processing temperature to develop maximum purity of the assembly, and is impervious to helium penetration to sustain the vacuum level. Metal end-closures and the arcing chambers are of high-purity alloy to minimize contamination.

Enclosed in the interrupter is a stationary and a moving contact assembly. The moving contact has a travel of approximately one-half inch, its shaft passing through a flexible bellows which maintains vacuum integrity. Contacts are made of a special non-welding alloy.

Because the smallest amount of internal contamination can significantly shorten the life of a vacuum interrupter, a clean-room facility is used for interrupter production. Special care is taken to avoid even minute contamination from any source, whether it be dust particles, machining oils, or human body salts.

AccessoriesW-group reclosers can be supplemented with a number of accessories to provide added application flexibility. Some accessories modify the normal operating functions while others increase operating versatility; still others provide indicating functions. For each accessory installed on a particular recloser, a data plate is mounted on the sleet hood of the recloser.

Where required, accessory leads are brought into the recloser tank through a junction box mounted on the head casting.

Bushing-type, multi-ratio current transformers

Multi-ratio current transformers for operating meters or separate relays can be mounted on load-side bushings 2, 4, and 6 or the source-side bushings 1, 3, and 5 (Figure 11). These current transformers have only one primary turn – the bushing rod. They are available with secondary windings that provide primary/secondary-current ratios of either 600:5 or 1200:5. Different ratios can be obtained by connection to appropriate taps on their secondary windings.

Ratios obtainable from 600:5 and 1200:5 transformers are shown in Table 6.

Hydraulic ground-trip accessory

If the rated minimum zero-sequence (ground) current is exceeded, the hydraulic ground-trip mechanism – an oil-dashpot-type solenoid connected to paralleled BCT secondaries – trips the recloser. The hydraulic ground-trip mechanism accessory enables the recloser to protect against ground-fault currents lower than the recloser’s minimum phase-trip setting. For currents above the minimum phase-trip setting, recloser opening is governed by either the phase-trip series coil or the ground-trip coil, whichever is faster. Refer to Reference Data R280-91-7 for available delay curves.

The ground trip coil is operated from the bushing-type, multi-ratio current transformers mounted on the source-side bushings (1, 3, and 5) to produce the minimum ground-trip currents shown in Table 7. The current transformers must be ordered separately.

Electronic ground-trip accessory

Self-contained, independent, sensitive ground-fault tripping is also available with an electronically controlled ground-trip accessory that includes the following:• Fifteen fault-timing characteristics including inverse and definite-

time curves, or plug-in modules that are easily field changed.• Dual-timing capability.• Twelve minimum-trip levels, from 5 to 400 A.• Line powered; completely self-contained.• Precharging coil for consistent timings even when reclosing on a

permanent fault.

Fault-timing characteristics and timing operations are independent and separate from the recloser’s phase fault timing and TCCs. Counting to lockout is integrated with phase operations. The dual-timing feature enables coordination with other protective apparatus on the system.

Accessory control circuits are powered from the line through two current transformers mounted under the head casting on source-side bushings (Figure 13). Five amperes of line current is all that is required to maintain circuit charge and supply the trip operation.

Zero-sequence (ground) current is sensed by three parallel-connected current-sensing transformers mounted beneath the head casting on the load-side bushings. When the ground current exceeds the selected minimum-trip level, the control circuits actuate the magnetic tripper to trip the recloser. Ground overcurrent timing is according to the time-current characteristics programmed with plug-in modules on the accessory circuit board.

When the recloser automatically recloses or is otherwise closed by electrical operation of its closing solenoid, an initial arming feature instantly charges the accessory control circuits. This enables the ground-trip accessory to respond immediately, according to its programmed time-current characteristic, should a ground fault be present.

If the system downline from the recloser is energized by other than electrical operation of the recloser (such as the closing of an upline recloser or breaker), control-circuit arming time must be added to the published time-current characteristic for proper TCC coordination. Further information that can be used in anticipating such circumstances is found with the published time-current characteristics on this accessory; refer to Eaton's Cooper Power Systems Reference Data R280-91-12 ,Types RX, RV, W, WV, VW, VWV Time-Current Curves.

Ground-trip blocking switch

A ground-trip blocking switch can be provided for either ground-trip accessory. The hotstick-operated blocking switch (Figure 14) is normally mounted on the recloser. The manual lever-operated blocking switch (Figure 16) is for remote mounting.

Remote trip

When energized from an external source, the remote trip accessory (Figure 16) trips the recloser, just as when the series trip coil operates. Normal automatic reclosing follows. Reclosing will occur even if the solenoid remains energized. Should this condition occur, the recloser will operate to lockout. The remote trip accessory leads are brought out of the recloser tank through a separately specified accessory junction box.

Electrical ratings are shown in Table 8.

otee:N The remote trip accessory cannot be installed on a recloser equipped with a ground-trip accessory (hydraulic or electronic) since both occupy the same space and operate the same trip-lever mechanism.

Low-voltage DC closing

By specifying a dc-closing solenoid from Table 17 and this accessory, the recloser can be closed by an externally controlled low-voltage dc power source rather than from the primary high-voltage source. A separately specified accessory junction box with input terminal block is also required. Low voltage is especially desirable in loop and load-transfer schemes where the recloser can be operated regardless of which side of the unit is energized. Current requirements for dc closing are 55 A at 125 Vdc or 58 A at 48 Vdc.

Low-voltage AC closing

With the addition of a modified closing contactor equipped with a full-wave diode bridge (Figure 17), the dc closing solenoid can be operated from a low-voltage ac source. Current requirements for ac closing are 51 A at 120 Vac or 34 A at 240 Vac.

Auxiliary switch

Remote indication of recloser contact position or switching of other devices can be accomplished with an auxiliary switch. A three-stage switch is mounted on the recloser (Figure 18). Each stage has two independent contacts a and/or b. When the recloser’s main contacts are open, the a contacts are also open and the b contacts are closed. Table 10 shows the recloser/ auxiliary switch contact relationship.

Switch contacts are insulated for 600 V and have a continuous current rating of 10 A. The interrupting ratings of the auxiliary switch contacts are shown in Table 9 above.

Lockout-indicating switch

A lockout-indicating switch assembly can be added for remote indication of recloser lockout (Figure 19). The switch is particularly useful in load-transfer schemes.

Consisting of two single-pole, double-throw switches in a weatherproof housing, the assembly is actuated by the recloser’s manual operating lever. A threaded opening for a one-half inch IPS conduit or cable grip is provided.

Electrical ratings of the lockout-indicating switch are shown in Table 11.

Remote lockout

The remote lockout accessory (Figure 20) enables an external control to trip the recloser and operate the lockout mechanism.

The remote lockout accessory leads are brought out of the recloser tank through a separately specified accessory junction box with terminal block.

Electrical ratings of the remote lock-out accessory are shown in Table 12.

otee:N To provide complete remote operation, the remote lockout accessory is usually employed with the remote close accessory.

Remote close

When energized from an external source, the remote close accessory closes a locked-out recloser by manually pulling the operating handle to the CLOSE position, actuating the high-voltage closing solenoid contactor to close the recloser. The external control circuit for this accessory requires a connection that includes a customer-furnished, normally open, momentary contact switch wired in series with the solenoid.

Electrical ratings of the remote close of locked-out recloser accessory are shown in Table 13.

Types VWE, VWVE37, VWVE38X, WE, WVE27, and WVE38X, three-phase electronically controlled reclosers

The W-group electronically controlled, three-phase automatic circuit reclosers from Eaton's Cooper Power Systems provide reliable, economical overcurrent protection for distribution circuits rated through 38 kV. Compact in design, these reclosers can be easily installed on poles or in substations. The six reclosers in this group provide service-proven dependability and long operating life.

Commanded by an Eaton's Cooper Power Systems electronic recloser control, these automatic circuit reclosers offer superior coordination and application capability unmatched by other system protection apparatus. Their broad application capabilities permit the user to select exactly the right recloser for the protection required.

Recloser settings are configured by the electronic control with accurate, preset tripping characteristics and reclosing times. Trip times are precise and unvaried, enabling close coordination with other protective devices on the system. When system requirements change, program settings are easily altered with no sacrifice of accuracy or consistency.

When needed, application expertise backed by world-wide recloser application experience is available. Knowledgeable design capability – based on more than fifty years of recloser manufacturing experience – has made Eaton's Cooper Power Systems the industry leader. Progressive product development programs, using the latest technologies, have resulted in the production of modern, efficient Eaton's Cooper Power Systems reclosers.

W-group reclosers, like all reclosers from Eaton's Cooper Power Systems, are designed and manufactured in accordance with ANSI® C37.60.

The six distinct reclosers in the W-group – Types VWE, VWVE27, VWVE38X, WE, WVE27, and WVE38X – offer a broad selection of ratings to fit varied system needs. Recloser and control accessories enable further tailoring of the protective program to achieve maximum system operating flexibility. Mounting equipment, available for pole or substation, eases installation of the recloser wherever system requirements demand.

Technical Data 280-40Effective July 2014Supersedes May 2005

Ratings and characteristic featuresThree-phase protection on systems rated 2.4 through 14.4 kV is provided by Types WE or VWE reclosers. Types WVE27 or VWVE27 can be applied on systems rated through 24.9 kV. Higher-voltage system protection (24.9 through 34.5 kV) is provided by Types WVE38X and VWVE38X reclosers. A ratings summary for this recloser group is shown in Table 1. For ratings and basic application information for other reclosers, refer to Catalog Section 280-05.

OperationSensing current transformers, mounted in the recloser, supply fault-sensing information to the electronic control. Tripping and closing signals from the control energize the operating circuits in the recloser. Due to a single CT ratio for all ratings, minimum-trip values of the electronic control are independent of the continuous-current and interrupting ratings of the recloser. Flexibility in coordination with other protective devices is provided by dual time-current characteristics from a choice of available curves, minimum trip values, reclosing and resetting time settings, and a selection of accessories.

Closing solenoidContact-closing energy is provided by a closing solenoid that also stores energy in the trip mechanism. High-voltage closing solenoids are connected to the system on the source-side of the recloser. Selection of solenoid voltage rating is based on the system phase-to-phase operating voltage.

Low-voltage closing solenoids can be employed. Auxiliary voltage must then be supplied to the recloser.

Oil or vacuum interruptionA choice of interrupting medium is available. Types WE, WVE27, and WVE38X reclosers use oil as the arc interrupting medium. Movable bridge-type contacts provide two breaks in series on each phase. Separate self-generating interrupter chambers at each of the two breaks provide for effective interruption of all currents, from minimum load to rated maximum fault.

Vacuum interruption, used in Types VWE, VWVE27, and VWVE38X, offers considerably longer duty cycles and long contact life. A single break on each phase is accomplished by separating contacts inside the vacuum interrupter. All arcing is contained within the vacuum envelope. Low-energy arc interruption in a vacuum results in far less shock and contact wear, extending the recloser mechanism life.

Because interruption within the vacuum envelope does not add contaminants to the insulating oil, recloser maintenance is minimized and intervals between oil changes can generally be extended.

Surge protectionBest operating results are achieved if reclosers are protected with surge arresters. On line applications, arrester protection is recommended on both sides of the recloser. (If protection is on one side only, it should be on the source-side.) In substations, arresters should be on the load-side. Eaton's Cooper Power Systems distribution-class arresters provide excellent protection and are available with mounting brackets to fit our reclosers. Refer to Catalog Sections 235-35 and 235-99.

Features and detailed description W-group electronically controlled, three-phase oil reclosers protect systems operating through 34.5 kV. Refer to Ratings and Specifications section. These ratings, and the wide range of programmable settings provided by the electronic control, permit meeting a variety of application requirements.

Basically the same in operation as three-phase hydraulically controlled reclosers (Catalog Section 280-30), these reclosers possess the added operating flexibility of electronic control.

A choice of oil or vacuum as the arc interrupting medium is available:• Types WE, WVE27, and WVE38X reclosers use oil (Figure 1).

Bridge-type contacts provide two current breaks in series for each phase. Each current break employs a separate, vented, self-generating, arc-interrupting chamber for effective interruption of the recloser’s full current range.

• Vacuum interruption is utilized by Types VWE, VWVE27, and VWVE38X reclosers (Figure 2). A single break on each phase is accomplished by separating a set of contacts within the vacuum chamber. Low-energy arc interruption in a vacuum extends the duty cycle and results in less shock and demonstration, extending recloser mechanism life.

Closing force is supplied by a closing solenoid, which is energized by line-to-line connections inside the recloser. This solenoid closes the main contacts of all phases while simultaneously charging the opening springs in preparation for a tripping operation. The control signals tripping and closing.

Fault currents are sensed by three 1000:1 ratio sensing current transformers, located in the recloser. These CTs provide a continuous measurement of line current, monitored by the electronic control. When current level exceeds the programmed minimum trip level, the magnitude of the overcurrent is integrated with time, using a programmed time-current curve characteristic. The control then energizes the trip coil in the recloser. This releases the tripping springs, opening the main contacts of all three phases. If reclosing is programmed, the control then activates the closing mechanism. The reclosers are self-contained; they require no external power source (except as required by certain accessories).

The electronic recloser control provides simple determination of phase- and ground-trip sequences and operations-to-lockout. Minimum phase-and ground-trip values, timing of tripping, and reclosing and resetting timing are adjustable at the control, without de-energizing the recloser.

Application flexibility is enhanced by dual-timing characteristics from a choice of time-current curves for phase and ground tripping levels.

ConstructionRecloser

Like other Eaton's Cooper Power Systems reclosers, these are designed for long service life and minimum maintenance. Heads are aluminum castings. Tanks are heavy-gauge steel, finished with polyester powder paint (Munsell 5BG 7.0/0.4; light gray is the standard color).

An “O”-ring gasket confined in a groove provides an oil-tight and weatherproof seal between the head and tank. A 1/2 in. brass oil-sampling-and-drain valve, located near the bottom of the tank, is standard.

Bolts through the head casting support the recloser, securing it to the mounting. The complete internal mechanism is suspended from the head casting, allowing tank removal without disturbing the mechanism and head assembly. Lowering the tank with a wire rope winch (available as an accessory) permits easy access to the mechanism.

Insulating supports, from which the three interrupters are suspended, are made of filament-wound glass epoxy for high electrical and mechanical strength, and moisture resistance.

Oil interrupters

Types WE, WVE27, and WVE38X use oil as the arc-interrupting medium.

Fast arc interruption (down to 2 1/2 cycles clearing) is furnished by bridge-type contacts (Figure 3), providing two current breaks in series per phase. The bayonet-type, silver-plated, tungsten-alloy moving contacts resist erosion and provide good conductance. The stationary-contact assemblies are tulip-type clusters of silver-plated contact fingers held by garter springs. The contacts are self-cleaning due to the wiping action of opening and closing.

Each current break has a self-generating-type arc interrupter structure including a series of vented chambers. As the contacts open, the arc generates gas pressure in the upper chamber, which blasts oil across the arc and out through the vents. As a result, arc extinction is fast, and arc energy levels do not increase as quickly at higher fault-current levels.

Vacuum interrupters

Types VWE, VWVE27, and VWVE38X use vacuum as the interrupting medium.

Vacuum interrupters (Figure 4) provide fast, low-energy arc interruption with long contact and interrupter life, low mechanical stress, and maximum operating safety. With arc interruption taking place in a vacuum, contact and interrupter life are several times greater than with interruption in oil, virtually eliminating interrupter maintenance. Because of the shorter contact stroke, mechanical stress and wear on the mechanism is substantially reduced.

Eaton's Cooper Power Systems vacuum interrupters are designed with a metal and ceramic housing for maximum strength and long-term vacuum integrity. The high-alumina ceramic has more than five times the strength of glass, permits a higher processing temperature to develop maximum purity of the assembly, and is impervious to helium penetration to sustain the vacuum level. Metal end-closures and the arcing chambers are of high-purity alloy to minimize contamination.

Enclosed in the interrupter is a stationary and a moving contact assembly. The moving contact has a travel of approximately one-half inch, its shaft passing through a flexible bellows that maintains vacuum integrity. Contacts consist of a special non-welding alloy.

Because the smallest amount of internal contamination can significantly shorten the life of a vacuum interrupter, a clean-room facility is used for interrupter production. Special care is taken to avoid even minute contamination from any source, including dust particles, machining oils, or human body salts.

Recloser operationTripping

When current flow exceeds the minimum-trip value needed to satisfy the programmed timing characteristics, the control energizes a trip solenoid in the recloser. This solenoid releases a latch, and a spring-loaded toggle assembly opens the recloser contacts.

Figure 4. Cross section of a typical vacuum interrupter used in vacuum interrupting reclosers.

280-40-9

www.cooperpower.com

Closing

Closing force – and the force to charge the opening springs – is supplied by a high-voltage closing solenoid connected phase-to-phase (Figure 5). When the recloser contacts are closed, the solenoid plunger is latched in the down position. This latch is tripped simultaneously with the release of the recloser opening springs, and the solenoid plunger moves upward for a closing operation.

At the programmed reclosing time, the electronic control energizes a rotary solenoid in the recloser. Movement of the rotary solenoid allows a high-voltage contactor to close momentarily, connecting the closing solenoid to the line. The plunger is pulled into the solenoid closing the recloser contacts and charging the opening springs. Plunger movement also opens the high-voltage contactor (Figure 6), de-energizing the closing solenoid. Closing operation of the recloser mechanism activates a switch (b contact) in the recloser, disconnecting the rotary solenoid from the electronic control.

The closing solenoid is designed for repeated-momentary rather than continuous operation. If a malfunction of the solenoid plunger or the closing-coil contactor results in the closing solenoid energizing for an extended period, a closing-solenoid fuse within the recloser opens the high-voltage circuit, protecting the closing solenoid from the thermal damage.

Manual operation

The recloser can be manually tripped at any time by lowering the yellow manual operating handle under the sleet hood. With the handle down, the control cannot close the recloser.

Raising the yellow handle on a recloser may or may not close the recloser pending the control type.

Raising the yellow handle on a recloser controlled with a Form 4C, FXB, Form 5, or Form 6 control will not close the recloser. Manual closing is accomplished by raising the yellow handle and then moving the manual control switch to the close position. The recloser will close if the recloser closing coil has the proper voltage applied to it.

Raising the yellow handle on a recloser controlled with a Form 3A control will close the recloser unless the control is in the lockout position. If the control is in the lockout position when the yellow handle is raised, manual closing is accomplished by moving the manual control switch to the close position. The recloser will close if the recloser closing coil has the proper voltage applied to it. Similarly, the recloser can be operated from the manual control switch on the electronic control panel, provided the manual operating handle is up. A red contact position indicator flag, adjacent to the manual operating handle, shows recloser contact position.

Current sensing

Three 1000:1-ratio current sensing transformers are provided with the recloser, supplying both phase and ground (zero-sequence) currents. They are connected to the control cabinet by means of a plug-in cable, which can be up to 125 ft. in length, thus permitting remote mounting of the control away from the recloser.

Electronic controlsTypes VWE, VWVE27, VWVE38X, WE, WVE27, and WVE38X reclosers are controlled by Eaton's Cooper Power Systems electronic recloser control. Eaton's Cooper Power Systems offers a choice of electronic controls to use in conjunction with these reclosers.

The Form 6 control, shown in Figure 7, provides maximum protective hardware design and simple interactive graphical interfaces for complete user customization. All standard control operating parameters including minimum trip levels, time-current curve selection, and sequences of recloser operation are keyboard programmable.

This control utilizes a powerful PC-based interface software to configure control settings, record metering information, and establish communication parameters. It also provides analysis tools that include fault locating, event recording, and oscillography functions.

For complete descriptive and ordering information on the Form 6 control, refer to Bulletin 03010.

The Form 5 control, shown in Figure 8, performs outstanding protection, metering, and communication functions. The control includes three serial ports, one designated for the PC based configuration software, to meet expanded SCADA and automation applications. The Form 5 control includes extensive per-bushing metering to monitor up to six voltages for open tie applications, a customizable data profiler, sequence of event recorder, and system alarms, all available through serial communications.

Numerous application problems are solved with loop scheme availability, switch mode, and triple-single applications.

For complete descriptive and ordering information on the Form 5 control, refer to Bulletin 99012.

NOVA15, NOVA27, and NOVA38 three-phase, microprocessor- controlled recloser

Description

280-42-1

Technical Data 280-42Effective May 2014Supersedes December 2009

Ratings and characteristic featuresThree-phase protection on systems rated 2.4 through 14.4 kV is provided by NOVA15 reclosers. NOVA27 reclosers can be applied on systems rated through 27.6 kV. Higher-voltage system protection at 34.5 kV is provided by NOVA38 reclosers. A ratings summary for NOVA reclosers is shown in Tables 1–3. For ratings and basic application information of other reclosers from Eaton’s Cooper Power Systems, see Catalog Section 280-05.

Operation

Sensing current transformers, embedded in the recloser, supply fault-sensing information to the electronic control. Tripping and clos-ing signals from the control energize the operating circuits in the recloser. Due to a single CT ratio for all ratings, minimum-trip values of the electronic control are independent of the continuous-current and interrupting ratings of the recloser.

Flexibility in coordination with other protective devices is provided by varied time–current characteristics from a choice of standard or customized curves, minimum trip values, reclosing and resetting time settings, and a selection of accessories.

Vacuum interruption

A single break on each phase is accomplished by separating contacts inside the vacuum interrupter. All arcing is contained within the vacuum envelope. The patented axial-magnetic vacuum interrupters, used in NOVA reclosers, offers extended and increased duty cycles compared with oil or radial-magnetic interrupters. The axial-magnetic field keeps the arc in a diffused mode, resulting in less arc power to be dissipated, resulting in low thermal stress, suitable for encapsulation.

Surge protection

Best operating results are achieved if reclosers are protected with surge arresters. On line applications, arrester protection is recommended on both sides of the recloser. (If protection is on one side only, it should be on the source side. In substations, arresters should be on the load side.) Eaton’s Cooper Power Systems distribution-class arresters provide excellent protection and are available with mounting brackets to fit our reclosers (see Catalog Sections 235-35 and 235-99).

Ordering informationAll NOVA reclosers include a Form 6 microprocessor-based recloser control. The Form 6 control includes full protection, TCC Editor, metering, and diagnostics for your application needs.

Features and detailed descriptionNOVA microprocessor-controlled, three-phase reclosers protect systems operating through 34.5 kV (see Ratings and Specifications section of this catalog). These ratings and the wide range of programmable settings provided by Eaton’s Cooper Power Systems electronic controls permit meeting a variety of application requirements.

Recloser operation

Fault currents are sensed by three 1000:1 ratio sensing current transformers embedded in the recloser. These CTs provide a continuous measurement of line current, monitored by the electronic control. When current level exceeds the programmed minimum trip level, the magnitude of the overcurrent is integrated with time, using a programmed time–current curve characteristic. The control then signals the trip in the recloser, opening the main contacts of all three phases.

The control signals tripping and closing. The recloser always maintains energy for a tripping operation following a closing operation.

The electronic recloser control provides determination of phase- and ground-trip sequences and operations to lockout and reclosing and resetting timing, adjustable with the control without de-energizing the recloser.

Construction

Recloser

Designed for long service life and no maintenance, the NOVA recloser has three solid-polymer interrupter modules with embedded current transformers and a standard aluminum mechanism housing; light gray is the standard color.

Cycloaliphatic-epoxy polymer encapsulation provides solid insulation and maintenance-free, environmentally safe operation. There is no monitoring or maintaining of gas pressure or oil levels; there are no toxic or environmentally unfriendly materials. There are no foam fillers or insulation seals, eliminating potential moisture ingress areas. The NOVA recloser module exhibits good absorption of elastic energy and resistance to cracking and crack propagation. Additionally, durable environmental properties make the solid polymer suitable for outdoor applications, including seacoasts, deserts, and areas of high pollution.

Surface tracking

The cycloaliphatic epoxy is highly resistant to contaminants and resists tracking and flashovers under extreme pollution levels to reduce both flashovers and the associated cost of repairs.

Hydrophobicity

The module maintains excellent hydrophobicity, a property characterized by water beading into isolated drops, and is highly resistant to moisture absorption. Hydrophobicity prevents continuous sheets of water from forming leakage current paths that deteriorate the creepage withstand level.

Ultraviolet resistance

The cycloaliphatic epoxy resists ultraviolet radiation damage even in harsh climates, maintaining a smooth, unblemished, self-cleansing surface with low-adhesion to contaminants.

Tensile strength

Outstanding tensile and flexural strength characteristics mean the NOVA recloser modules are tough and non-fragmenting, reducing shipment and handling charges.

Shed design

The shed design utilizes alternate-sized skirts. The major sheds shield and protect the minor sheds to enhance the hydrophobicity and ultraviolet resistance of the module, eliminate formation of microcracks, and ensure extra-protected creepage. Additionally, sharp edges direct water away from the unit. Water paths and ice formations are effectively eliminated.

Flashover recoveryFlashovers occur when an object, usually wildlife, contacts energized parts of the equipment. The NOVA recloser minimizes the effect of flashovers with remarkable physical resilience, arc-quenching proper-ties, and a self-healing ability. NOVA recloser can withstand the enor-mous forces experienced during faults without wholesale damage and allows re-energizing after external flashover without cleaning.

Vacuum interrupters

NOVA reclosers use vacuum as the interrupting medium. Vacuum interrupters (Figure 3) provide fast, low-energy arc interruption with long contact and interrupter life, low mechanical stress, and maxi-mum operating safety. With arc interruption taking place in a vacu-um, contact and interrupter life are several times greater than with interruption in oil, virtually eliminating interrupter maintenance.

Eaton’s Cooper Power Systems vacuum interrupters are designed with a metal and ceramic housing for maximum strength and long-term vacuum integrity. Oxygen-free, high-conductivity copper, stainless steel, and a nickel-copper alloy are used in the vacuum interrupters. The high-alumina ceramic has more than five times the strength of glass, which permits a higher processing temperature to develop maximum purity of the assembly, and is impervious to helium penetration, maintaining the vacuum level. Additionally, it provides wear resistance, chemical resistance, and a high dielectric strength.

Enclosed in the interrupter are a stationary and a moving contact assembly. The moving contact has a travel of approximately one-half inch, its shaft passing through a flexible bellows that maintains vacuum integrity. Contacts consist of a high purity copper sintered with aluminathermic chromium.

Because the smallest amount of internal contamination can significantly shorten the life of a vacuum interrupter, special care is taken to avoid even minute contamination from any source, including dust particles, machining oils, or human body salts. No paraffinic oils are used in the machining process, all machined parts are put through a cleaning/degreasing process, and then all components are electro-polished in a positive-pressure, air-filtered area. A Class 100 clean room facility is used for the final interrupter production. The furnaces employ a custom-designed, three-stage pumping system to yield high levels of vacuum. Every vacuum interrupter is then tested and tracked with individual serial numbers.

Electronic control

NOVA15, NOVA27, and NOVA38 reclosers are controlled by an Eaton’s Cooper Power Systems three-phase electronic recloser control. A choice of microprocessor-based controls are available to use in conjunction with these reclosers.

Control-powered interface

The Type D NOVA recloser mechanism (see Figure 4) with the control-powered interface is fully operational with Form 5 and Form 6 VTC-ready, microprocessor-based controls equipped with the required dc-to-dc converter, interface circuit, and a fully shielded 19-pin cable. It is not compatible with the Types F3A nor FXB controls. The control-powered interface includes a 19-pin receptacle on the recloser and an internal heater (for humidity control) powered from the control input power supply (ac or dc). The dc-to-dc converter board converts the control’s 24 Vdc battery supply to 53 Vdc to charge the trip/close capacitors in the NOVA recloser mechanism. The dc-to-dc converter board also houses voltage monitoring and conditioning circuits that protect the battery from failure and provide trip/close operations without ac power. In the absence of ac power to the electronic control, the control battery will provide the trip and close operations. A complete four-trip sequence with minimal reclose intervals as configurated for each control is obtainable without ac power. The recloser and control system is capable of exceeding over one thousand operations on battery power only.

Auxiliary-powered interface

The Type B NOVA recloser mechanism (see Figure 5) with the auxiliary-powered interface is fully operational with standard Form 6 microprocessor-based controls and standard 14-pin control cables. The auxiliary-powered interface includes a 14-pin receptacle on the recloser and an internal heater (for humidity control) powered from the auxiliary input power supply.

The Type B NOVA recloser mechanism, with the auxiliary-powered interface, requires a voltage source of 48 Vdc, 125 Vdc, 250 Vdc, 120 Vac, or 240 Vac, which must be specified at the time of order. The auxiliary-powered interface is connected to a 2-pin male receptacle located next to the 14-pin female control receptacle. The voltage source is used to maintain power to the trip-and-close capacitors in the recloser and to power the heaters.

DC auxiliary input

The trip-and-close capacitors are maintained from the dc source. Upon loss of the dc power, the trip-and-close capacitors will maintain trip and close power for several minutes. If the trip-and-close capacitors are discharged, the recloser is inoperative until dc power is resumed.

AC auxiliary input

The trip-and-close capacitors are charged through both the ac auxiliary input power and the recloser control. Upon loss of ac power, the capacitors will be continuously charged from the control battery to allow tripping and will also be trickle-charged to allow for back-up closing. The charge on the capacitors will be maintained for the duration of the control battery power. Allow one minute between back-up close operations to recharge the capacitors. However, the NOVA recloser is ready to trip immediately after performing a back-up closing. Should the battery power discharge to the disconnect level, back-up closing is disabled until ac auxiliary power is resumed. Apply ac auxiliary input power to the NOVA recloser to recharge the capacitors.

Manual operation

The recloser can be opened manually with a hotstick to pull down the yellow manual OPEN handle under the sleet hood. With the handle in the OPEN position, the control cannot close the recloser.

The recloser is closed, following a manual open, by pushing the yel-low handle back under the sleet hood and then using the micropro-cessor control to close the recloser.

Similarly, the recloser can be operated from the manual control switch on the electronic control panel, provided the manual operat-ing handle is up. A red contact position indicator flag, adjacent to the manual operating handle, shows recloser contact position.

Internal voltage sensor option

The NOVA recloser is available with internal voltage sensors at time of order. Using a high-voltage resistor within each interrupter module with source-side connections, the sensing option, cable, and control support a magnitude accuracy of 2% or better and a phase degree accuracy of ±1.5°. The internal voltage sensing option is compatible with a Form 5 or Form 6 Pole-Mount controls.

Accessories

Auxiliary switch

A three-stage auxiliary switch can be provided as an accessory. Each stage has two independent contacts that permit any desired combination of “a” (follow state of recloser contacts) and “b” (opposite recloser contacts) positions. The switch contacts are insulated for 600 V and have a continuous current rating of 10 A. Their interrupting ratings are shown in Table 5.

Terminals

The standard terminal is an eyebolt, 1/0–500 mcm (630 A). Eyebolt 4/0–1000 mcm (800 A), 2-hole and 4-hole, flat-pad terminals, and stud-type terminals are available as an accessory.

Pole-mounting hanger

A pole-mounting hanger, which bolts directly to the recloser frame, is available for pole-mounting installation.

Arrestor-mounting brackets

The arrestor-mounting bracket accessory can be bolted to the recloser frame and pole-mounting hanger for the addition of inboard and outboard arresters. The arresters are not included with the brackets.

Substation-mounting frame

A substation-mounting frame accessory is available for substation-mounting applications.

GeneralVSA-group electronically controlled, three-phase, automatic circuit reclosers with vacuum interrupters from Eaton's Cooper Power Systems, provide reliable and economical overcurrent protection for 15 kV distribution systems.

VSA-group reclosers are available with ratings up to 1200 amps continuous and 20,000 amps interrupting current, for line and substation applications. A choice of electronic recloser controls enables the user to meet a wide variety of application requirements.

The use of vacuum as the interrupting medium and air as the insulating medium, improves safety and substantially reduces long term maintenance costs. The reclosers in this group provide service-proven dependability and long operating life.

Commanded by an Eaton's Cooper Power Systems electronic recloser control, these automatic circuit reclosers offer superior coordination and application capability, unmatched by other system protection apparatus. The variety of available VSA-group ratings permits the user to select precisely the right recloser for the protection required.

Recloser operations are programmed on the electronic control panel with accurate, preset tripping characteristics and reclosing times, enabling close coordination with other protective devices on the system. When system requirements change, program settings are easily altered with no sacrifice of accuracy or consistency. Recloser and control accessories enable further tailoring of the protective program to achieve maximum system operating flexibility.

When needed, application expertise, backed by world wide recloser application experience, is readily available. Knowledgeable design capability – based on over 50 years of recloser manufacturing experience – has made Eaton's Cooper Power Systems the industry leader. Progressive product development programs, using the latest technologies, have resulted in the production of modern, efficient Eaton's Cooper Power Systems reclosers.

Since the majority of faults are temporary in nature, they can be cleared with only a momentary circuit interruption. Therefore, permanent outages are usually prevented. With outage time kept to a minimum, customer service and system reliability is improved and utility income is maintained.

VSA-group reclosers, like all reclosers from Eaton's Cooper Power Systems, are designed and built in accordance with ANSI® C37.60.

RatingsVSA-group reclosers can be applied in a wide variety of protective schemes on distributions systems ranging from 2.4 through 14.4 kV. Basic ratings are shown in Table 1.

Characteristic featuresFault-sensing information for VSA-group reclosers is supplied to the electronic control by bushing-type current transformers mounted in the recloser. Tripping and closing signals from the control energize operating circuits in the recloser.

Minimum-trip values of the control are independent of the continuous current and interrupting ratings of the recloser. Flexibility in coordination with other protective devices is provided by dual time-current characteristics available from a broad choice of time-current curves, a wide range of minimum-trip values, and a variety of programmable reclosing times.

Energy to operate the vacuum interrupters is provided by a motor-driven operator supplied from a 240 Vac source. The motor operator closes the recloser by charging the closing springs, which in turn provides the force to close the vacuum interrupters and charge the opening springs.

Since their introduction in 1966, Eaton's Cooper Power Systems vacuum interrupters have had an excellent reliability record and have grown to be the most complete line of vacuum switchgear available in the industry.

Mounting equipmentVSA-group reclosers are furnished in standard frames with corner lifting eyes. Mounting equipment is available for either pole or substation installation of the recloser (See Table 6 for mounting accessories).

Surge protection Best operating results are achieved when reclosers are protected with surge arresters. On line applications, arrester protection is recommended on both sides of a recloser. If protection is to be provided on one side only, it should be on the source side. In substations, arresters should be located on the load side.

Eaton's Cooper Power Systems distribution-class surge arresters provide excellent protection. See Catalog Section 235-35 for information about the UltraSIL™ Polymer-Housed VariSTAR™ surge arrester and Catalog Section 235-99 for the UltraSIL Polymer-Housed Evolution™ surge arrester.

Features and detailed description

Figure 1. VSA20A three-phase, air-insulated vacuum recloser with inspection cover removed.

RecloserVSA-group three-phase reclosers from Eaton's Cooper Power Systems feature vacuum interruption with air insulation and low-voltage motor operation. These reclosers are designed for circuit protection on systems operating through 14.4 kV.

Because of the large selection of continuous and interrupting current ratings and the flexibility provided by Eaton's Cooper Power Systems electronic recloser controls; VSA-group reclosers can be applied to meet a wide variety of requirements.

The vacuum interrupters in VSA reclosers provide reliable, shock free fault-current interruption with long interrupter life. The combination of vacuum interruption and air insulation provides longer maintenance intervals and lower maintenance costs than comparable oil-insulated reclosers. Vacuum interruption also provides greater safety for indoor applications than arc interruption in oil.

Closing and tripping operations of the recloser are both powered by springs. The motor-operator loads the closing springs, which charge the opening springs during closing.

An external 240 Vac source supplies power for the motor operator and the cabinet heaters. The 240 Vac supply is not required to trip the recloser.

Fault currents are sensed by 1000:1-ratio bushing current transformers mounted in the recloser (2000:1 current transformers are used in VSA20 and VSA20A reclosers), which provide sensing of both phase and ground (zero sequence) currents. They provide a continuous measurement of line current that is monitored by the recloser control. When the control’s programmed minimum trip level is exceeded, the control energizes the trip solenoid in the recloser operating mechanism, opening the recloser.

ConstructionEaton's Cooper Power Systems air-insulated vacuum reclosers offer extra-long service life and require minimal maintenance. Duty cycles are four times those of comparably rated oil-interrupting reclosers. Vacuum interrupter contacts, as well as the entire recloser, require no service other than periodic maintenance inspection.

Housings are fabricated of hot-rolled steel which is phosphatized to resist corrosion, then finished with polyester powder paint. Finish color is light gray, Munsell 5BG 7.0/0.4

Nonferrous alloys are used for mechanism linkages; stainless steel is used for shafts and hardware. Other steel parts are plated. Needle bearing or hard brass bushings are swaged into mechanism plates and linkages to provide long, trouble-free life for moving parts.

All gears and latches are permanently lubricated; sealed ball bearings are used in the motor.

For ease of inspection, all internal parts are readily accessible by removing an inspection panel on either side of the recloser.

Vacuum interrupters are mounted independently of the bushings. The bushing rods clamp to a current transfer member of the interrupter mounting assembly. Therefore, the bushings can be replaced quickly and easily without disturbing the interrupter or requiring any interrupter adjustment.

Insulating supports for the three interrupters are made of filament-wound glass epoxy for high electrical and mechanical strength and moisture resistance.

Cabinet heaters are provided in both the operator mechanism cabinet and the interrupter mechanism cabinet. The heaters are supplied from the 240-Vac auxiliary power source and are connected through a DPST on-off toggle switch and one amp fuses. The mechanism cabinet heater operates at 57 watts. The enclosure heaters operate at 115 watts total.

WEATHERPROOF OPERATOR CABINETprovision for padlocking; window to view contact position indicator.

Motor operationVSA-group air-insulated, vacuum reclosers employ a 240 Vac, motor-driven operating mechanism to charge closing and opening springs.

Tripping

Recloser tripping employs stored spring energy. When line current exceeds the programmed minimum-trip value, in one or more phases, the control energizes a trip solenoid in the operating mechanism. The solenoid trips a latch which releases a spring-loaded toggle assembly, opening the recloser contacts and a switch which interrupts the 24-volt signal from the control. Maximum clearing time is 2-1/2 cycles.

Tripping, because it employs stored spring energy released by a 24-volt signal from the control, will occur even if the 240-volt supply is lost.

Closing

Closing energy, as well as the force to charge the opening springs, is supplied by the motor operating mechanism, through motor-loaded closing springs. A 240 Vac motor charges the closing springs through a multi-stage gear drive. When 240 Vac is present, the motor is automatically operated to keep the closing springs in a charged state.

To close the recloser, the control initiates a signal which energizes a solenoid in the recloser operating mechanism. Once actuated, the solenoid releases the closing springs, which close the vacuum interrupters and charge the opening springs.

Stored energy provides multiple operationsShould the recloser’s 240 Vac motor supply voltage be lost while the closing spring is charged and contacts are closed, an Open-Close-Open sequence remains stored in the recloser operating mechanism. If the recloser trips under these conditions, the stored closing operation allows an immediate reclosing, if required. After such a closing, one additional trip operation then remains stored. Once closed, the recloser always contains energy for at least one trip operation.

Manual operationA closed recloser can be manually tripped from inside the operator cabinet, using the RESET-TRIP knob, or from outside the cabinet by pulling down the Manual Trip pull-ring. When the recloser is manually tripped, the closing circuit is opened to prevent reclosing. The recloser can be manually restored to service by placing the RESET-TRIP knob at RESET and moving the manual control switch on the recloser control to CLOSE. The manual control switch on the recloser control panel can also be used for tripping.

The recloser can be manually closed by pulling down the Manual Close Pullring located under the operator cabinet.

An emergency means is provided to manually close VSA-group reclosers on a de-energized line in the absence of the 240 Vac power supply.

A hand crank can be applied to the motor to charge the closing springs. Once charged, the closing springs can be released either from inside or from below the operator mechanism cabinet. As with electrical operations, the opening springs are charged by release of the closing springs, so even a manually closed unit has sufficient stored energy for a trip operation.

Vacuum interruptersThe high quality vacuum interrupters used in VSA-group reclosers are manufactured exclusively at the Distribution Switchgear plant. Eaton's Cooper Power Systems vacuum interrupters are used worldwide in the industry’s broadest line of fault protection and switching apparatus, where they have established a proven record of long term reliability.

Vacuum interrupters provide fast, low energy arc interruption with long contact and interrupter life and low mechanical stress. With arc interruption taking place in a vacuum, contact and interrupter life are four times greater than with interruption in oil. At the same time, mechanical stress and wear on the mechanism is substantially reduced. Combined, these factors result in greatly reduced maintenance costs over the life of the recloser.

Vacuum interrupters from Eaton's Cooper Power Systems are designed with a metal-and-ceramic housing for maximum strength. The high-alumina ceramic used in Eaton's Cooper Power Systems vacuum interrupters permits a high processing temperature to develop maximum purity of the assembly and is impervious to helium penetration. Metal end closures and the arcing chambers are of high-purity alloys to minimize contamination.

Enclosed in the interrupter is a stationary and a moving contact assembly. The moving contact has a travel of 7/16 in., its shaft passing through a flexible bellows which maintains vacuum integrity. Contacts are made of a special non-welding alloy.

Because even the smallest amount of internal contamination can significantly shorten a vacuum interrupter’s life, a state-of-the-art clean-room manufacturing facility is used for vacuum interrupter production. Special care is taken to avoid even minute contamination; whether it be from dust particles, machining oils, or human body salts.

Microprocessor-based control for maximum flexibilityThe operation of a VSA-group recloser is commanded by an Eaton's Cooper Power Systems electronic recloser control.

The Form 6 control, shown in Figure 4, provides maximum protective hardware design and simple interactive graphical interfaces for complete user customization. All standard control operating parameters including minimum trip levels, time-current curve selection, and sequences of recloser operation are keyboard programmable.

This control utilizes a powerful PC based interface software to configure control settings, record metering information, and establish communication parameters. It also provides analysis tools that include fault locating, event recording, and oscillography functions.

The Form 6 rack mount substation interface accessory enables application of Form 6 rack mount controls and VSA reclosers to substation installations.

Located in the motor operator cabinet, the substation interface accessory allows the Form 6 rack mount control to be located up to 500 ft. from a VSA recloser. (Table 9). The factory-installed interface accessory may be powered by a either a 24, 48, or 125 Vdc substation battery, as specified at time or order. The quiescent battery drain upon the substation is only 40 milliamperes. All VSA reclosers include a 14 pin control cable receptacle to provide convenient connection of the Form 6 rack mount recloser control to either the KA85ME control cable or KME6-1859/ KME6-1811 junction boxes.

For complete descriptive information on the Form 6 control, refer to Bulletins B280-00031 and B280-00032.

Type VSO three-phase electronically controlled recloser

IntroductionThe benefits of automatic-reclosing overcurrent protection can be realized on higher voltage distribution systems with Eaton’s Cooper Power Systems Type VSO electronically controlled, oil-insulated vacuum recloser. A high continuous current rating and a high fault-current-clearing capability make the Type VSO recloser an ideal selection for substation or main feeder protection applications. Your system benefits from:• High reliability resulting from the application

of time-tested vacuum interruption and control technologies to this higher-rated recloser

• Extended maintenance intervals with long-life maintenance-free vacuum interrupters that eliminate oil contamination from arcing by-products

• Simplified coordination with a familiar Form 3A electronic recloser control, or enhanced coordination flexibility with the Form 4C microprocessor-based recloser control

Basic Ratings

The VSO recloser has a rating of 560 amps maximum continuous current (extendable to 800 amps with an accessory) and 12000 or 16000 symmetrical amps maximum interrupting current at a maximum voltage of 38 kV.

Operating

Reclosers clear most faults with only momentary current interruption since the majority of faults are temporary in nature; thus, extended outages are usually prevented. With outage time kept to a minimum, customer service is improved and utility income is maintained. The Type VSO recloser includes an integral box frame fabricated of welded angle and channel steel that facilitates handling and mounting. The frame can be quickly assembled into an Eaton’s Cooper Power Systems substation mounting extension or single-pole hanger.

The recloser controls available provide the Type VSO recloser with a wide range of operating parameters to simplify coordination with other protective devices on a system.

Sensing-current transformers mounted inside the recloser provide line-current information to the recloser control. Tripping and closing commands from the control energize operating circuits in the recloser.

Operation of the recloser contacts is accomplished through the release of charged opening and closing springs. A motor-and-gear-train mechanism charges the closing springs; release of the closing springs closes the main contacts and charges the opening springs. Energy to operate the motor must be supplied to the recloser from an external 240 Vac source.

Current interruption takes place within vacuum interrupters that are suspended in oil from a mechanism frame under the head of the recloser. The head mechanism transfers forces from the operator mechanism to the moving contact in each of the three vacuum interrupters, causing them to move simultaneously through a one-inch stroke.

Surge protection

Best operating results are achieved when reclosers are protected with surge arresters. On line applications, arrester protection is recommended on both sides of a recloser. If protection is to be provided on one side only, then it should be on the source-side. In substations, arresters should be located on the load-side. Eaton’s Cooper Power Systems, distribution-class surge arresters provide excellent protection for the Type VSO recloser. See Technical Data 235-99, UltraSIL™ Polymer-Housed Evolution™ Surge Arrester or Technical Data 235-35, UltraSIL Polymer-Housed VariSTAR™ Surge Arrester for information.

The electronically controlled, oil-insulated, three-phase Type VSO vacuum recloser from Eaton’s Cooper Power Systems can be used in substations or in close-in feeder applications where it would be subject to high fault current levels.

Vacuum interrupters provide a single break on each phase through separation of contacts within each vacuum envelope. All arcing is contained within the interrupters. Low energy arc interruption in a vacuum results in far less shock and demonstration, extending the recloser mechanism life. Vacuum interruption offers longer duty cycles and long contact life.

The force required to trip and close the recloser contacts is provided by the release of charged opening and closing springs in the operator cabinet. A motor-operated mechanism, powered from an external 240 Vac supply, charges the closing springs. Release of the closing springs closes the recloser contacts and also charges the opening springs.

Line current is sensed by three 1000:1 ratio current transformers mounted on bushings 1, 3, and 5 under the recloser head. They provide the recloser control with a continuous measurement of line current.

When the programmed minimum-trip is exceeded, and after the programmed time delay, the control energizes a trip solenoid in the recloser to release the charged opening springs.

When the recloser contacts open, the recloser control activates the closing mechanism. Energy to operate the trip solenoid and activate the closing mechanism is provided by the control.

The Type VSO recloser is designed and built in accordance with ANSI® C37.60. Each recloser is thoroughly tested before shipment.

ConstructionIn common with other reclosers from Eaton’s Cooper Power Systems, Type VSO reclosers are designed for long service life with minimum maintenance. The recloser head is an aluminum casting. The tank is fabricated of heavy-gauge steel and is finished with a corrosion-inhibiting-epoxy prime coat, followed by a finish coat of thermosetting acrylic paint. Finish color is light gray, Munsell 5BG 7.0/0.4.

The oil-filled tank can be lowered and raised easily by one person with a windlass accessory, usable whether the recloser is mounted in a substation frame or on a pole. An oil sampling-and-drain valve, oil level sight gauge, and oil dipstick are provided as standard features.

An oil-tight, weather-resistant seal between the head and the tank is assured by a Buna-N synthetic rubber gasket confined in a groove in the head to provide controlled compression.

The recloser head is attached to a welded angle- and channel-steel box frame which facilitates handling and mounting. The tank is suspended within the box frame from the head. Each interrupter is independently suspended from the internal mechanism under the recloser head in a way which eliminates mechanical stress on the bushings as well as any need for adjustment between the bushing and interrupter. Wet-process porcelain bushings are oil-filled, capacitively graded type.

Two targets, visible through windows in the operator cabinet door, provide continuous (easily readable) indications of contact position and closing spring charge state. Contact position indication is either CLOSED (white letters on red background) or OPEN (white letters on green background). Spring charge state indication is either SPRING CHARGED (black letters on yellow background) or SPRING DISCHARGED (black letters on white background).

A four-stage auxiliary switch is provided as standard. Normally set for four “a” and four “b” contacts, the switch can be programmed for other “a” and “b” combinations totaling eight. It is operated by the recloser mechanism and is wired to a terminal block in the operator cabinet. The switch can be used to provide a remote indication of contact position or to switch other devices, such as alarm circuits, coincidentally with recloser contact opening and closing.

OperationTripping

Line current in all three phases is sensed by 1000:1 ratio current transformers on bushings 1, 3, and 5 under the recloser head. Continuous signals from the CTs, proportional to line currents, are routed to the recloser control, where they are monitored.

When the line current flows in excess of the programmed minimum trip level, in one or more phases, and after a time delay based on the programmed time-current characteristic, a trip solenoid in the operating mechanism is energized by the control. The solenoid trips a latch that releases the charged trip springs and mechanism. A linkage simultaneously operates all three phases, opening the recloser contacts and a switch which interrupts the trip signal from the control.

Closing

As with contact opening, contact closing force is provided through the release of stored spring energy. The closing springs are charged by operation of a 240 Vac motor and gear train. Upon receiving a closing signal from the control, a solenoid energizes, tripping a latch which releases the closing springs. When released, the closing springs cause the operating mechanism to close the vacuum interrupter contacts and simultaneously charge the opening springs. Immediately following the release of the closing springs, the 240 Vac motor runs to recharge the springs in preparation for the next closing operation. Limit switches interrupt the supply to the motor and the signal from the control when the closing springs are fully charged. Spring charging time is less than one second.

An external 240 Vac source supplies power for the motor operator. An undervoltage relay opens a contact in the motor circuit if the 240-volt motor supply voltage falls below 165 volts. This prevents the motor from operating on inadequate voltage, which could result in motor stalling and burnout.

If the 240-volt supply voltage is lost, the recloser can still perform a limited number of trip and close operations, operating from the stored spring energy. If power loss occurs while the main contacts are closed (and the motor has run to recharge the closing springs), the capability exists to trip, close, and trip again. If power loss occurs while the main contacts are open, the capability exists to close once and trip once.

Manual

A closed recloser can be tripped manually from inside the operator cabinet by moving the Trip-Reset knob to TRIP or from outside the cabinet by pulling down on the yellow trip ring under the cabinet. When the recloser is manually tripped, the closing circuit is opened to prevent reclosing. The recloser can be manually restored to service either by moving the Trip-Reset knob to RESET and pressing the Manual Close lever down or by pushing up on the yellow trip ring and pulling down on the close ring.

The manual operation described in the preceding paragraph involves levers that are mechanically linked to the operating mechanism. The recloser can also be tripped and closed with the Manual Control switch on the recloser control panel. An emergency means is provided to manually close the recloser (on an energized line if necessary and with the closing springs discharged) in the absence of 240 Vac auxiliary power. A crank stored inside the operator cabinet door is engaged with the motor shaft and cranked through approximately 150 turns to charge the closing springs; a closing operation can then be initiated.

Vacuum interruptersVacuum interrupters provide a single break on each phase. Vacuum interrupters provide fast, low-energy arc interruption with long contact and interrupter life, low mechanical stress, and maximum operating safety. With arc interruption taking place in a vacuum, isolated from the insulating oil, contact and interrupter life is greatly extended, and oil contamination and maintenance are virtually eliminated. At the same time, mechanical stress and wear on the mechanism is minimal.

Eaton’s Cooper Power Systems vacuum interrupters are designed with a metal and ceramic housing for maximum strength. The high-alumina ceramic has more than five times the strength of glass, permits a higher processing temperature to develop maximum purity of the assembly, and is impervious to helium penetration to sustain the vacuum level. Metal end closures and the arcing chambers are of high-purity alloy to minimize contamination. Enclosed in the interrupter is a stationary and a moving contact assembly. The moving contact has a travel of one inch, its shaft passing through a flexible bellows which maintains vacuum integrity. Contacts are made of a special non-welding alloy.

Recloser controlType VSO recloser is electronically controlled by an Eaton’s Cooper Power Systems recloser control. A choice of two controls can be used in conjunction with this recloser.

The Form 3A control, shown in Figure 4, is a solid-state electronic control system, using conventional, discrete, electronic components. Control operating parameters are programmed via plug-in modules. These programming components provide precise values for operating parameters, which include: time-current characteristics, reclosing delay intervals, and minimum trip levels. The control provides simple selector switch determination of phase- and- ground-trip sequences and operations to lockout. Operating characteristics can be quickly and easily changed to meet new application requirements by simply changing the dial settings or plug-in component(s), without removing the recloser from service.

The Form 3A control can be equipped with a variety of accessories to provide remote operation and monitoring for SCADA applications. Some of the available accessories include: remote fault indication, remote modification of operating characteristics, and remote operation.

The Form 4C Type ME microprocessor-based recloser control, shown in Figure 5, incorporates computer technology to provide enhanced application versatility and ease of operation. All standard control operating parameters including; phase- and ground-fault minimum trip levels, time-current curve selection, and sequences of recloser operation, are keyboard programmable. Simple keyboard sequences, and dedicated function keys, provide convenient programming and interrogation of the control’s various operating parameters. A large LCD display provides control feedback during programming and integration, and either front panel LCD indicators provide control and recloser status, at a glance.

The control is equipped with 38, keyboard-selectable, time-current curves, which are interchangeable for use as either phase or ground. Each of the curves can be custom modified to provide an almost unlimited coordination flexibility.

The control provides a wide range of standard features, which include: supervisory operation, remote status indication, fault indication via LCD targets and counters, Fault Footprint™ event recorder, recloser duty monitor, demand metering, and load profile monitor.

The microprocessor-based control can also be equipped with an accessory supervisory input/output board to extend the supervisory operation capabilities of the control.

AccessoriesAccessories available for the Type VSO recloser are described in the following paragraphs.

Bushing-type, multiratio current transformers

Multiratio current transformers for operating relays or load meters can be mounted on the source-side bushings (Figure 6), the load-side bushings, or both the source- and load-side bushings. Whether three or six current transformers are ordered, the accessory includes six extra-length bushings to accommodate the current transformers and maintain an equal terminal-top height. (When the accessory is ordered for one side only, extender sleeves are included on the opposite side). Addition of the transformers increases terminal top height by five inches.

These current transformers have only one primary turn – the bushing rod. They are offered with secondary windings that provide primary/secondary current ratios of either 600:5 or 1200:5. Different ratios can be obtained by connection to appropriate taps on their secondary windings. The ratios obtainable from 600:5 and 1200:5 transformers, and the corresponding accuracy classes, are shown in Table 4.

For ease of connection and ratio selection, secondary taps are factory-wired to terminal blocks (one corresponding to each transformer) in the mechanism cabinet (Figure 7). Wiring from meters or relays is routed into the cabinet by the customer and joined to two of the five terminals on each block to obtain the ratio desired. Two thumbscrews in each of the blocks, positioned to short and ground the current transformers for shipping, are then removed and repositioned to complete electrical connection of the device. To order bushing-type multiratio current transformers see the Recloser Accessories listing under ORDERING INFORMATlON.

Current metering

Useful in load balance studies, current metering is offered for the Type VSO recloser in the form of three 3-1/2-inch socket-mounting thermal ampere-demand meters. The five-amp movement/five-amp scale meters are available with or without instantaneous indicators in addition to the average indicators.

A meter trough mounting-and wiring kit contains the parts required to conveniently mount the trough to the substation extension alongside the control and make electrical connections to the current transformer terminal blocks inside the mechanism cabinet.

Current metering can also be ordered in the upper portion of a double-size Form 3A electronic control cabinet.

800-Amp continuous current

The continuous current carrying capability of the Type VSO recloser can be increased, extending its rating from 560 amps to 800 amps, with this accessory. It consists of larger bushing terminals stainless steel bushing clamps, and associated small hardware. Two types of bushing terminals are offered: a 1-1/8 inch-12 stud type terminal and an eyebolt terminal that accepts 2/0-1000 MCM copper or aluminum conductor.

120-Volt AC motor operator

For installations where 240 Vac auxiliary power is not accessible, the Type VSO recloser can be ordered with an accessory which permits operation on 120 Vac. All of the standard recloser capabilities are retained.

Potential-type battery charger

Form 3A electronic recloser controls contain battery charging circuits that require a 120 Vac supply voltage. For those installations where 120 Vac is not available at the control, or when a prior model Form 3 control (which may not have a battery charger) is to be used, the recloser must be equipped with a battery charger. Installed in the operator cabinet, chargers are provided in either of two versions: 240 Vac for the standard Type VSO recloser, or 120 Vac for the Type VSO recloser equipped with the 120 Vac motor operator accessory.

External spring charging

Enhanced operator safety is provided by this accessory, which relocates the receptacle for the hand spring charging crank from the side of the operator cabinet to its underside (Figure 9). When recharging springs in a recloser on a live circuit, a lineman need not have any part of his body closer to exposed live parts than the underside of the cabinet to effectively operate the crank.

External contact position indicator

Spotting a tripped recloser in a row of substation-mounted reclosers, or spotting a tripped pole-mounted recloser from a moving vehicle is easy with this indicator accessory (Figure 10). A green cylinder (1-1/4-inch diameter x 2 inches long), mechanically linked to the mechanism is enclosed in a sleeve extending from the bottom of the mechanism cabinet. When the recloser contacts are open, the cylinder extends from the sleeve (green visible); when the contacts are closed, the cylinder retracts into the sleeve (green hidden). The cylindrical indicator design provides a definite indication easily seen from various positions around the cabinet end of the recloser, eliminating possible difficulty in viewing and interpreting a flag-type indicator from some positions.

Flat-pad terminals

Two-hole or four-hole flat-pad type bushing terminals (Figure 11) of silver-plated, red brass alloy are offered for the Type VSO recloser.

Mounting EquipmentSingle-pole hanger

Consisting of two horseshoe-shaped, galvanized channel-steel brackets, the Type VSO recloser single-pole hanger (Figure 12) forms a strong rigid supporting frame when joined to the recloser’s welded box frame. The hanger brackets are conveniently bolted to the box frame with four 1/2-inch bolts while the recloser is on the ground. The recloser/hanger assembly is then hoisted into position and secured to the pole with two 3/4-inch through-bolts (customer-furnished). Two reinforcing washers are included with the accessory.

Substation Extension

Compact and adjustable, the Type VSO recloser substation extension (Figure 13) provides a structure of ample strength to support the recloser and a complement of accessories. Consisting of four galvanized angle-steel legs, galvanized strap-steel braces, and associated hardware, the extension is easily assembled to the recloser frame. A mounting strap is provided for the recloser control, located to allow space for mounting the metering accessory alongside. The extension is adjustable in three-inch increments to provide a terminal-top height of nine feet, nine inches to eleven feet.

Tank Lifting Windlass

One person can easily lower and raise the oil-filled tank with this accessory, which is usable with pole-mounted or substation-mounted Type VSO reclosers. The windlass, (Figure 14) features a 30-to-1 ratio worm-and-pinion gear box that minimizes cranking effort and holds the tank stationary any time cranking is stopped and the operator’s hand is removed from the crank. A shear pin connects the crank to the gear box shaft to guard against overstressing the mechanism when the tank is fully raised. Supplied partly assembled to newly ordered Type VSO reclosers, the windlass accessory can also be ordered separately for addition to reclosers in the field.

Recloser featuresRatings and characteristic features

Single-phase protection on systems rated 2 .4 through 14 .4 kV is pro-vided by SPEAR15 reclosers . SPEAR27 reclosers can be applied on systems rated through 27 .0 kV . Higher-voltage system protection at 34 .5 kV is provided by Type SPEAR38 reclosers . A ratings summary for SPEAR reclosers is shown in Tables 13 .

Operation

Sensing current transformers, embedded in the recloser, supply fault-sensing information to the electronic control . Tripping and clos-ing signals from the control energize the operating circuits in the recloser . Due to a single CT ratio for all ratings, minimum-trip values of the electronic control are independent of the continuous-current and interrupting ratings of the recloser .

Flexibility in coordination with other protective devices is provided by varied time–current characteristics from a choice of standard or cus-tomized curves, minimum trip values, reclosing and resetting time settings, and a selection of accessories .

Vacuum interruption

A single break on each phase is accomplished by separating con-tacts inside the vacuum interrupter . All arcing is contained within the vacuum envelope . The patented axial-magnetic vacuum interrupters, used in SPEAR reclosers, offers extended and increased duty cycles compared with oil or radial-magnetic interrupters . The axial-magnetic field keeps the arc in a diffused mode, resulting in less arc power to be dissipated, resulting in low thermal stress, suitable for encapsula-tion .

Surge protection

Best operating results are achieved if reclosers are protected with surge arresters . On line applications, arrester protection is recom-mended on both sides of the recloser . (If protection is on one side only, it should be on the source side . In substations, arresters should be on the load side .) Eaton’s Cooper Power Systems distribution class arresters provide excellent protection and are available with mounting brackets to fit SPEAR reclosers .

Recloser operation

Fault currents are sensed by one 1000:1 ratio sensing current trans-former embedded in the recloser . This CT provides a continuous measurement of line current, monitored by the electronic control . When current level exceeds the programmed minimum trip level, the magnitude of the overcurrent is integrated with time, using a programmed time–current curve characteristic . The control then sig-nals the trip in the recloser, opening the main contact of the encap-sulated vacuum bottle .

The control signals tripping and closing . The recloser always main-tains energy for a tripping operation following a closing operation . The electronic recloser control provides determination of phase trip sequences and operations to lockout and reclosing and resetting tim-ing, adjustable with the control without de-energizing the recloser .

Construction

Recloser

Designed for long service life and no maintenance, the SPEAR recloser has a solid-polymer interrupter module with an embedded current transformer and a standard mild steel mechanism housing; light gray is the standard color .

Cycloaliphatic-epoxy polymer encapsulation provides solid insulation and maintenance-free, environmentally safe operation . There is no monitoring or maintaining of gas pressure or oil levels; there are no toxic or environmentally unfriendly materials .

There are no foam fillers or insulation seals, eliminating potential moisture ingress areas . The SPEAR recloser module exhibits good absorption of elastic energy and resistance to cracking and crack propagation . Additionally, durable environmental properties make the solid polymer suitable for outdoor applications, including seacoasts, deserts, and areas of high pollution .

Surface tracking

The cycloaliphatic epoxy is highly resistant to contaminants and resists tracking and flashovers under extreme pollution levels to reduce both flashovers and the associated cost of repairs .

Hydrophobicity

The module maintains excellent hydrophobicity, a property character-ized by water beading into isolated drops, and is highly resistant to moisture absorption . Hydrophobicity prevents continuous sheets of water from forming leakage current paths that deteriorate the creep-age withstand level .

Ultraviolet resistance

The cycloaliphatic epoxy resists ultraviolet radiation damage even in harsh climates, maintaining a smooth, unblemished, self-cleansing surface with low-adhesion to contaminants .

Tensile strength

Outstanding tensile and flexural strength characteristics mean the SPEAR recloser module is tough and non-fragmenting, reducing shipment and handling charges .

Shed design

The shed design utilizes alternate sized skirts . The major sheds shield and protect the minor sheds to enhance the hydrophobic-ity and ultraviolet resistance of the module, eliminate formation of microcracks, and ensure extra-protected creepage . Additionally, sharp edges direct water away from the unit . Water paths and ice formations are effectively eliminated .

Flashover recovery

Flashovers occur when an object, usually wildlife, contacts energized parts of the equipment . The SPEAR recloser minimizes the effect of flashovers with remarkable physical resilience, arc-quenching properties, and a self-healing ability . SPEAR reclosers can withstand

the enormous forces experienced during faults without wholesale damage and allows reenergizing after external flashover without cleaning .

Vacuum interrupters

SPEAR reclosers use vacuum as the interrupting medium . Vacuum interrupters (Figure 2) provide fast, low-energy arc interruption with long contact and interrupter life, low mechanical stress, and maximum operating safety . With arc interruption taking place in a vacuum, contact and interrupter life are several times greater than with interruption in oil, virtually eliminating interrupter maintenance .

Eaton’s Cooper Power System vacuum interrupters are designed with a metal and ceramic housing for maximum strength and long-term vacuum integrity . Oxygen-free, high conductivity copper, stainless steel, and a nickel-copper alloy are used in the vacuum interrupters . The high alumina ceramic has more than five times the strength of glass, which permits a higher processing temperature to develop maximum purity of the assembly, and is impervious to helium penetration, maintaining the vacuum level . Additionally, it provides wear resistance, chemical resistance, and a high dielectric strength .

Enclosed in the interrupter is a stationary and a moving contact assembly . The moving contact has a travel of approximately one-half inch, its shaft passing through a flexible bellows that maintains vacuum integrity . Contacts consist of a high purity copper sintered with aluminathermic chromium .

Because the smallest amount of internal contamination can significantly shorten the life of a vacuum interrupter, special care is taken to avoid even minute contamination from any source, including dust particles, machining oils, or human body salts . No paraffinic oils are used in the machining process, all machined parts are put through a cleaning/ degreasing process, and then all components are electro-polished in a positive-pressure, air-filtered area . A Class 100 clean room facility is used for the final interrupter production . The furnaces employ a custom-designed, three-stage pumping system to yield high levels of vacuum . Every vacuum interrupter is then tested and tracked with individual serial numbers .

Manual operation

The recloser can be opened manually with a hotstick to pull down the yellow manual OPEN handle under the sleet hood . With the handle in the OPEN position, the control cannot close the recloser .

The recloser is closed, following a manual open, by pushing the yellow handle back under the sleet hood and then using the electronic control to close the recloser .

Similarly, the recloser can be operated from the manual control switch on the electronic control panel, provided the manual operating handle is up . A red contact position indicator flag, adjacent to the manual operating handle, shows recloser contact position .

Accessories

Terminals

The standard terminal is an eyebolt, 1/0–500 mcm (630 A) . Eyebolt 4/0– 1000 mcm (800 A), 2-hole and 4-hole, flat-pad terminals, and stud-type terminals are available as an accessory .

Pole-mounting hanger

A pole-mounting hanger, which bolts directly to the recloser tank, is available for pole-mounting installation .

Arrester-mounting brackets

The arrester-mounting bracket accessory can be bolted to the recloser tank . The arresters are not included with the brackets .

Time-current curves are available for fast and delayed operations . Reclose intervals and reset time can also be programmed by the user .

High current lockout

The High Current Lockout (HCL) feature will automatically lockout the control when the current exceeds a programmed threshold . The active number of selectable operations to lockout is independently selectable for each protection profile .

Cold load pickup

The SPEAR control provides a Cold Load Pickup (CLPU) feature that will prevent the control from tripping due to short-term increases in current caused by loss of normal load diversity or feeder inrush . This feature has an independently programmable minimum trip value, time-current curve, reclose interval, and number of operations to lockout for each protection profile . The CLPU feature will also inhibit ‘normal’ overcurrent protection during the CLPU active time .

Hot line tag

The SPEAR control includes a Hot Line Tag (HLT) membrane push button that will block all Close operations, local or remote, for live-line work . The control will trip on one operation-to-lockout on the composite curve of the HLT definite time and the TCC1 curve, whichever is faster, when HLT is active . Hot Line Tag takes pre-cedence over Cold Load Pickup, Non-Reclosing, and Fast Trips Disabled . The Hot Line Tag time delay is independently selectable for each protection profile .

Fast trips disabled

The Fast Trips Disabled feature will ignore the normal TCCs and num-ber of trips and instead use the Fast Trips Disabled settings when Fast Trips Disabled is active . Fast Trips Disabled is independently selectable for each protection profile .

Sequence coordination

The SPEAR control Sequence Coordination feature will allow the control to step through selected operations in the operating sequence without tripping when a down-line recloser is proceeding through its reclose sequence . The number of advances is program-mable from one to three operations to provide trip coordination with the down-line recloser .

Manual close time delay

The SPEAR control includes a Manual Close Delay which provides a delay from the time the manual CLOSE button is pushed to the time the manual close operation is performed .

Metering

The SPEAR control comes equipped with a full complement of metering capabilities, which include instantaneous, demand, demand peak, and energy metering . The control will be capable of the follow-ing metering values:• Real and reactive power, including direction of power flow• Demand currents• Instantaneous currents• Instantaneous voltage• Instantaneous frequency• Energy• Instantaneous power factor• Metering Settings which include demand interval, and alarm

thresholds for current, voltage, frequency, power factor, frequen-cy, kVA, kVAR, and kW

Diagnostic tools

The SPEAR control comes complete with a suite of diagnostic tools to help troubleshoot problems, analyze system events and condi-tions, and monitor the life of your recloser . All diagnostic information is stored in non-volatile memory so even if the control loses power, all system and event information will remain intact .

Recloser wear monitor

The Recloser Wear Monitor will observe the life of the recloser appa-ratus by recording how many times the recloser has been opened as well as keep track of the current interrupted in percentage compared to preset total Duty Cycle Factor . The monitor allows for program-mable entries to preset the duty of an existing recloser .

Sequence of events recorder

The Sequence of Events (SOE) Recorder is capable of capturing dis-crete events such as Open/Close status changes, faults, mechanism failures, etc . The SOE places an accurate time stamp and analog information on the events and stores them in non-volatile memory so they won’t be lost in the event that the control loses power . The SOE recorder is capable of maintaining up to 1000 events and can record up to 48 different event types, including overcurrent trip, con-trol trip, non-reclose ON/OFF, external alarm, and control lockout .

Data profiler

A fully configurable data profiler is available which allows the user to collect information by sampling data at selectable intervals . These time-stamped values can then be viewed to determine weekly load profiles, hourly voltage and/or current fluctuations, battery voltage and current, and frequency . The number of days of information the data profiler can provide depends upon configuration parameters .

Contact input/output (I/O) module option

The SPEAR control comes pre-configured with two sets of Input and Output contacts . This feature permits connection of contact type input devices (switches, relays) and discrete indicating devices (relays, LEDs, lamps) to the SPEAR control to affect local discrete input/output . The SPEAR control is designed to only have a maxi-mum of 2 Inputs and Output contacts . Additional I/O is not required .

Communications

The SPEAR control is equipped with one communication accessory expansion bay offering versatile support for modern communication media . One distinct communication option is available, providing two-way, real time SCADA communications with a remote terminal unit (RTU), short or long-range radio, or other communication devic-es with DNP3 support . The following option is available:• RS-232 (isolated) Serial communication card

The expansion bay communication accessory concept offers high versatility with respect to communication medium and protocol support . Additional accessories are being continuously developed .

DescriptionThe Form 4D recloser control is the first in a line of fully integrated controls developed by Eaton’s Cooper Power Systems. These controls will feature a standard look and feel, and a universal platform that can be programmed for almost any protective application. This means one standard operating system and front panel to train field technicians on. That translates to fewer training expenses, reduced inventory, and a distribution system that is much easier to maintain.

In addition to the flexible and user-friendly platform, the new Eaton’s Cooper Power Systems controls will have the communications technology to take your system into the future. With fully modular communication compatibility, these controls will support cellular and radio communications utilizing the DNP3 and other serial and network protocols. Side panel RS-232, fiber-optic, Ethernet, and RS-485 ports are available for connection to SCADA or other devices. These ports are accessed by swinging the control panel forward.

The Form 4D recloser control provides phase and ground current sensing, and three-phase voltage sensing. The Form 4D control can compute power, energy, power factor, and power flow direction from these current and voltage inputs.

The standardized front panel of the Form 4D control can be used to program and interrogate the control, as well as to display metering and alarm information. Control parameters can also be programmed via personal computer using ProView NXG™ interface software. Temporary connection to the control can be made through the front panel USB port. The ProView NXG interface software includes the functionality to create and modify time-current curves (TCCs), and provides diagnostic information. The Form 4D control analysis tools include event recording, data profiling, and various metering capabilities.

Control featuresControl security

The Form 4D recloser control has multiple customer-programmable security codes to limit control programming and viewing function access to authorized personnel. The Form 4D control is capable of supporting strong passwords containing letters (upper and lower case), numbers, and symbols. The front panel Human-Machine Interface (HMI) includes a user-selected security code to access the settings. Plus, the ProView NXG interface software has its own security levels for multiple-user access.

Protection profiles

The Form 4D control provides two protection profiles, each capable of fully specifying the operation of the control. The protection profiles are selectable through the front-panel push-button interface or through the interface software and USB communication ports. Each protection profile contains overcurrent protection, voltage protection, frequency protection, sync check, sensitive earth fault protection, and operation settings.

Reclosing and overcurrent protection/TCCs

The Form 4D control offers flexible phase and ground overcurrent protection which can be programmed with up to four operations-to-lockout. Each time-current curve (TCC) can be individually programmed from up to fifty standard curves which can be further customized. Time-current curves are available for fast and delayed operations. The time-current curves are also selectable from a graphical TCC editor to visualize any modifications prior to configuring the control. Reclose intervals and reset time can also be programmed by the user.

TCC editor II

Coordination and actual time current modifications are available with a graphic, interactive TCC editor. The TCC Editor II includes a complete database of standard recloser industry time current curves, both ANSI® and IEC types, along with the ability to customize the TCCs with multipliers, constant time adders, or minimum response time adders. The user is also able to derive their own specific TCC through data point entry.

Sensitive earth fault

The Form 4D control includes Sensitive Earth Fault (SEF) protection, which will provide tripping of the recloser for ground currents below normal ground minimum trip elements. The SEF feature has programmable operations-to-lockout and reclose intervals independent of the ground settings and is independently selectable for each protection profile.

High current lockout

The High Current Lockout (HCL) feature will automatically lockout the control when the current exceeds a programmed threshold. The active number of operations-to-lockout is selectable for both phase and ground and is independently selectable for each protection profile.

Cold load pickup

The Form 4D control provides a Cold Load Pickup (CLPU) feature that will prevent the control from tripping due to short-term increases in current caused by loss of normal load diversity or feeder inrush. This feature has an independently programmable minimum trip value, time-current curve, reclose interval, and number of operations to lockout for each protection profile as well as for both phase and ground. The CLPU feature will also inhibit ‘normal’ overcurrent protection during the CLPU active time.

Hot line tag

The Form 4D includes a Hot Line Tag (HLT) switch that will block all Close operations, local or remote, for live-line work. The control will trip on one operation-to-lockout on the composite curve of the HLT definite time and the TCC1 curve, whichever is faster, when HLT is active. Hot Line Tag takes precedence over Cold Load Pickup, Non-Reclosing, and Fast Trips Disabled. The Hot Line Tag time delay is independently selectable for each protection profile.

Fast trips disabled

The Fast Trips Disabled feature will ignore the normal TCCs and number of trips and instead use the Fast Trips Disabled settings when Fast Trips Disabled is active. Fast Trips Disabled will have separate phase and ground settings and is independently selectable for each protection profile.

Ground trip precedence

The Form 4D control comes equipped with an option for Ground Trip Precedence. When ground trip precedence is selected to be active, the sequence uses the ground operations to lockout for fault current above both phase and ground minimum trip values.

Voltage protection

The Form 4D control includes three levels each of over- and undervoltage protection and includes single-phase and three-phase protection for both over- and undervoltage conditions. Both functions include a phase pickup, a phase time delay, a three-phase pickup, and three-phase time delay. One overvoltage and one undervoltage alarm is also provided.

Frequency protection

Six levels of frequency protection are included with the control, with each level configurable as either overfrequency or underfrequency. A frequency restoration function, which can be enabled or disabled, will allow the recloser to automatically close should the frequency return to within configured settings for a user-settable time.

Sync check

The Form 4D control includes sync check functionality, which is used to qualify any close signal to the recloser when enabled via the sync check settings. Sync check allows for closing for any combination of dead/live bus/line, and to perform anticipatory closing for a live bus/live line condition by calculating slip and anticipating the mechanism closing delay. In addition to the anticipatory close calculation, the sync check system performs verification of line and bus voltage magnitudes and frequencies to determine that they are within pre-determined ranges, and that the angular differences between the two systems is also within the pre-determined range.

Sequence coordination

The Form 4D control Sequence Coordination feature will allow the control to step through selected operations in the operating sequence without tripping when a down-line recloser is proceeding through its reclose sequence. The number of advances is programmable from one to three operations to provide trip coordination with the down-line recloser.

Manual close time delay

The Form 4D control includes a Manual Close Delay which provides a delay from the time the manual CLOSE button is pushed to the time the manual close operation is performed.

Metering

The Form 4D control comes equipped with a full complement of metering capabilities, which include instantaneous, demand, demand peak, and energy metering. The control will be capable of the following metering values:

• Real and reactive power for single- and three-phase, including direction of power flow.

• Demand currents on a per-phase basis.• Instantaneous currents, including ground current.• Instantaneous voltage on a per-phase basis.• Instantaneous frequency.• Energy on a per-phase basis.• Positive, negative, and zero sequence voltages.• Harmonics on a per-phase basis for voltage and current.• Instantaneous power factor on a per-phase basis.• Metering settings which include demand interval, and alarm

thresholds for current, single-phase kW, three-phase kW, single-phase kVAR, and three-phase kVAR.

Diagnostic tools

The Form 4D control comes complete with a suite of diagnostic tools to help troubleshoot problems, analyze system events and conditions, and monitor the life of your recloser. All diagnostic information is stored in non-volatile memory so even if the control loses power, all system and event information will remain intact.

Recloser wear monitor

The Recloser Wear Monitor will observe the life of the recloser apparatus by recording how many times the recloser has been opened as well as keep track of the current interrupted in percentage compared to preset total Duty Cycle Factor. The monitor allows for programmable entries to preset the duty of an existing recloser.

Sequence of events recorder

The Sequence of Events (SOE) Recorder is capable of capturing discrete events such as Open/Close status changes, faults, mechanism failures, etc. The SOE places an accurate time stamp and analog information on the events and stores them in non-volatile memory so they won’t be lost in the event that the control loses power. The SOE recorder is capable of maintaining up to 1000 events and can record up to 116 different event types, including overcurrent trip, control trip, non-reclose ON/OFF, external alarm, and control lockout.

Data profiler

A fully configurable data profiler is available which allows the user to collect information by sampling data at selectable intervals. These time-stamped values can then be viewed to determine weekly load profiles, daily harmonic disturbances, or hourly voltage fluctuations. The number of days of information the data profiler can provide depends upon configuration parameters.

Internal voltage sensingA four-wire cable and input receptacle accessory is required for Type NOVATM three-phase reclosers with the internal voltage sensing (IVS) option. Internal voltage sensors, located on the source side, indicate voltage magnitude within an accuracy 2% or better and a phase degree accuracy within 1.5 degrees (includes sensor, cable, and control). The 4-pin receptacle accessory is prewired to the voltage inputs on the control.

Contact input/output (I/O) module option

The Contact I/O Module option (Figure 2) permits connection of contact-type input devices (switches, relays) and discrete indicating devices (relays, LEDs, lamps) to the Form 4D control to effect local discrete input/output. The I/O module accessory is used for supplementing normal local controls and status indicators for Contact I/O functions.

The initial Contact I/O Module option contains four factory-set inputs and four outputs for Contact I/O functions. Each Form 4D control can accommodate four Contact I/O modules. Additional modules require user programming via the software.

• CLOSE Pushbutton: When pressed, the CLOSE pushbutton returns the control to the initial or home sequence position, clos-ing the recloser. The control is ready for the start of a new trip/close sequence.

• HOT LINE TAG ON/OFF: Hot Line Tag is provided for live-line work applications. All closing operations are disabled when the Hot Line Tag feature is activated.

Hot Line Tag prevents all closing attempts from the control and shifts protection to one trip-to-lockout on the composite curve of the Hot Line Tag definite time and the TCC1 curve (whichever is faster). Hot Line Tag takes precedence over Cold Load Pickup, Non-Reclosing, and Fast Trips Disabled.

Hot Line Tag is activated from either the operator panel toggle switch, local or remote communications, or configurable logic. All sources must be off to de-activate Hot Line Tag.

The Hot Line Tag function may only be reset by the source which initiates it.

One-touch function keys (Figure 11)

GND TRIP BLOCKED

The Ground Trip Blocked function blocks all ground sensing in the control for the active profile. This indicator is illuminated when Ground Trip Block is activated from the SCADA port, the interface software, or locally (via the front panel) causing the control to block all ground sensing.

NON RECLOSE

The control is operating in a non-reclosing mode when the NON RECLOSE indicator is illuminated. Non-reclosing mode disables any automatic reclosing operations. Non-reclosing does not alter the active TCC. Activation is possible from the SCADA port, the interface software, or locally (via the front panel).

SUPERVISORY OFF

When the SUPERVISORY OFF red indicator is illuminated, supervisory commands are blocked. Supervisory functions through the USB data ports are not blocked. Communications through the front panel USB port remain active independent of the status of the SUPERVISORY OFF switch. Activation of this function key is restricted to the operator panel. Operational data and metering information are available while the control is in the SUPERVISORY OFF position.

ALT PROFILE 1

The Form 4D control has two protection profiles; a normal profile, and Alternate Profile 1. When the operator panel display lights are active and the ALT PROFILE 1 indicator is not illuminated, the Normal profile is active. Only one profile can be active.

To select the alternate profile, press the ALT PROFILE 1 button.

To return to the Normal profile, press the ALT PROFILE 1 button to deselect it. These functions can also be completed remotely via communications interfaces.

Operation upon loss of ac power

The control is equipped with either an 8 Amp-Hour or 13 Amp-Hour 24 Vdc lead acid battery for operation upon loss of ac power. The control maintains full operation from the battery for a period of time dependent upon the battery size:

• 8 Amp-Hour – 24 hour (approximate) maximum (20°C)

• 13 Amp-Hour – 36 hour maximum (20°C)

Control programming settings and parameters – including event recorder – are stored in non-volatile memory and retained upon loss of control power. The time/date clock will continue to operate for approximately 30 days after loss of control power.

AccessoriesLow-voltage closing

The Low-Voltage Closing Accessory utilizes 120 or 240 Vac for closing power. Multiple low-voltage closing accessories are available for reclosers equipped with low voltage closing. The low-voltage closing accessories available for the Form 4D recloser control include the appropriate receptacles and wiring based upon the input supply voltage. Tables 4 and 5 list the available low voltage closing input/output receptacles and cables for the Form 4D control.
