DescriptionSectionalizers are used in conjunction with source-side protective devices such as reclosers or reclosing breakers to automatically isolate faulted sections of distribution lines. After sensing a cur-rent above a preselected level, the sectionalizer counts when the source-side protective device de-energizes the circuit. The sectionalizer can be set to open after 1, 2, or 3 counts. It does not inter-rupt fault current, but opens the section of the line within its protective zone during the open interval of the backup protective device.

Sectionalizers can be used in place of fuses or between the reclosing device and a fuse. They only detect current above a specified level and have no time–current characteristics. This provides a current-coordination range from minimum pickup to the maximum allowable momentary value of the sectionalizer.

Sectionalizers offer these operating advantages: • Manual load-breaking capabilities up to 2.2

times their normal load ratings as determined by the actuating coil

• Fault close-in ability completely independent of operator speed

• No accidental opening under overload due to a damaged link

• Automatic or manual operation in any weather

Ratings and characteristicsType GH single-phase hydraulically controlled sectionalizer can be applied to distribution systems within the ratings shown in Table 1.

A simple internal mechanism operates the sectionalizer. The mechanism incorporates a series-connected actuating coil, a plunger, and a trip piston to count and trip. The sectionalizer opens automatically but must be closed manually with the yellow operating handle under the sleet hood. The sectionalizer can also be tripped manually with the operating handle.

Operation

A sectionalizer is a self-contained circuit-opening device. It automati-cally opens its contacts after a backup recloser or circuit breaker de-energizes the circuit. Because a sectionalizer is not designed to interrupt fault current, it is always used in series with a backup fault-interrupting device.

A sectionalizer has no time–current characteristics, making it easily applicable to both new and existing coordination schemes. Figure 1 details the internal parts of the Type GH sectionalizer.

Surge protection

Sectionalizers operate best when protected with surge arresters. On line applications, arrester protection is recommended on both sides of the sectionalizer. If protection is to be provided on one side only, install the arrester on the source side. Eaton's Cooper Power Systems distribution-class arresters provide excellent protection; see Catalog 235-99, UltraSIL™ Polymer-Housed Evolution™ Surge Arresters.

Sectionalizer operationA sectionalizer senses overcurrent interruptions and opens after 1, 2, or 3 such interruptions occur. It does this in two steps:

1. When the sectionalizer senses a current above its actuating level, it arms (prepares to count). The count occurs when current through the sectionalizer is interrupted or falls below a certain value.

2. If the predetermined number of counts are registered within a definite time period, the sectionalizer opens when the backup device has interrupted current flow to the system.

Example

Figure 2 shows a typical application. A sectionalizer is located downline from an automatic circuit recloser. Basic coordination between the sectionalizer and the recloser consists of the following:

1. Establishing the sectionalizer’s actuating level proportional to the recloser’s trip level;

2. Programming at least one less count for the sectionalizer than the number of trips to lockout of the backup recloser. In this case, the recloser might be set for four operations to lockout and the sectionalizer for its maximum of three counts.

A fault occurs downline from the sectionalizer, in its normal protection zone. The sectionalizer and the backup recloser both sense the fault current. The sectionalizer arms to count on the overcurrent. The recloser trips and de-energizes the line. Current through the sectionalizer is interrupted, and the sectionalizer counts.

If the fault is temporary, it may be cleared by the recloser’s first two fast operations. Since neither the recloser nor the sectionalizer has completed its full operations sequence, both will reset for another complete sequence.

If the fault is permanent, the recloser continues through its programmed operations and the sectionalizer counts each trip operation. After the recloser has tripped for the third time, the sectionalizer completes its sequence of counts, opens, and isolates the fault. The recloser restores the rest of the system by reclosing, and, since it has not reached its programmed number of operations to lockout, it resets for another full sequence.

A quick-close feature of Eaton's Cooper Power Systems hydraulic sectionalizers allows safe closing – even on a faulted line – up to the rated making current. Closing is accomplished by springs, and contact speed is independent of operator effort.

The quick-reset provision automatically resets the sectionalizer one count as soon as it opens. If closed in on a faulted line – even immediately after tripping – the sectionalizer remains closed until its backup device has cleared the fault. The sectionalizer then opens normally while the line is de-energized.

Counting mechanism operation

The hydraulic sectionalizer is actuated when its series-actuating (solenoid) coil is subjected to a current flow exceeding 160% of its continuous-current rating. The response of the hydraulic control mechanism to an overcurrent is illustrated in Figures 3, 4, and 5.

Figure 4 shows the hydraulic control in its usual at-rest condition. The actuating component of the control – the solenoid plunge – functions as a pump. With normal load current flowing through the solenoid coil, spring pressure holds the solenoid plunger at the top of its stroke.

When current flowing through the solenoid coil reaches actuating level, the resulting magnetic field pulls the plunger down (Figure 4).

This downward motion closes the check valve at the bottom and forces a charge of oil up through the plunger into the space vacated by the plunger. The oil pressure opens the check valve at the top of the plunger, permitting oil flow. The plunger is held down until the current flow through the coil drops to about 40% – or less – of its actuating level.

In a typical sectionalizer counting operation, current flow through the coil is interrupted when the backup recloser interrupts the overcurrent. With the coil de-energized, the magnetic field is lost and the plunger is returned to its up position by the compressed spring, as shown in Figure 5.

Upward movement of the plunger closes the top check valve so that the oil charge above the plunger (Figure 4) is forced upward. This raises the trip piston, and the sectionalizer now has registered one count. If the sectionalizer has been set for more than one count, the sequence is repeated with each overcurrent until the trip piston engages the trip latch and opens the sectionalizer contacts.

After each count, the trip piston begins to reset slowly. The time during which it remembers previous counts is called sectionalizer memory time. If the fault is temporary and is cleared before the sectionalizer opens, the piston resets. If the programmed number of counts is completed within the sectionalizer memory time, the sectionalizer opens and must be closed manually.

Figure 4. Overcurrent pulls down solenoid plunger, forcing charge of oil up. Mechanism is armed to count.

Figure 5. When current drops to 40% of actuating level, plunger returns up, raising trip piston for first count.

Application recommendationsThe following basic coordination principles should be observed in the application of hydraulic sectionalizers:

1. The sectionalizer’s minimum-actuating-current rating should be approximately 80% of the minimum-trip rating of the source-side protective device.

Note: This requirement is usually satisfied by pairing the sectionalizer with an equally continuous-current-rated hydraulic recloser The continuous-current and minimum-actuating-current ratings of the sectionalizer correspond to – and are compatible with – hydraulic recloser ratings.

2. The sectionalizer should be set to open one count less than the total operations to lockout of the backup device.

Note: This rule need not apply when several sectionalizers are in series; successive units may be set for 1, 2, or 3 counts less than backup recloser operations.

3. Momentary and short-time ratings of the sectionalizer must not be exceeded. Follow the steps below to check this requirement:

A. To establish a cumulative time– current curve for the backup device, add the clearing-time curves for the operations that occur prior to opening of the sectionalizer.

B. Plot this curve on the GH short-time current carrying chart (Figure 6) as applicable.

C. Read the current at the intersection of the cumulative curve of the backup device and the applicable short-time curve of the sectionalizer.

D. The sectionalizer should be located where available fault cur-rent does not exceed the value in Step C.

4. The backup device’s total accumulated operation time must be equal to – or less than – the sectionalizer’s memory time.

Note: Hydraulically controlled sectionalizers were originally designed for use with hydraulically controlled reclosers. The hydraulically controlled recloser generally has a maximum two-second reclosing time; the hydraulically controlled sectionalizer has a memory time that is fixed, but will coordinate with any hydraulic controlled recloser.

For other electronic- or relay-controlled backup fault interrupting devices which may have longer resetting times, information to accurately determine whether or not the hydraulically controlled sectionalizer will coordinate is presented in the following paragraphs.

Figure 6. Short-term current-carrying capacity.

Coordination of sectionalizer with backup protective devices Coordination of Types GH hydraulically controlled sectionalizer with backup reclosers or breakers is a function of the sectionalizer’s maximum oil temperature and the backup device’s operating sequence.

Sectionalizer oil temperature

Sectionalizer memory time depends upon the resetting of the hydraulic counting mechanism. Thus, memory time is a function of oil viscosity which in turn depends upon oil temperature.

The temperature rise of the oil due to current flow through the coil, contacts and lead wires at various load-current levels is shown in Table 5.

Assuming a period of load-current flow prior to sectionalizer operation, add the temperature rise to the sectionalizer ambient temperature to determine the approximate maximum oil temperature.

Operating sequence of backup device

Figure 7 shows the portions of the backup operating sequence which must be considered when determining proper coordination. These are the appropriate fault times and reclosing times when the sectionalizer must keep the proper count. Called Total Accumulated Time (TAT), it is the time (sec) from the instant of interruption on the first fault operation to the instant of interruption on the last fault operation that the sectionalizer counts before opening.

EXAMPLE 1

For a Type GH sectionalizer set to open after counting three fault interruptions, the total accumulated time of the backup device is the sum of the first and second reclosing times and the second and third trip times: TAT=R1 + F2 + R2 + F3.

EXAMPLE 2

If the sectionalizer is set to open after two counts, total accumulated time would be the sum of the first reclosing time and the second trip time: TAT= R1 + F2.

EXAMPLE 3

If the sectionalizer is set for one-count-to-open, sectionalizer memory time is not involved and the sectionalizer will always coordinate. However, when the one-count-to-open setting is used, inrush currents must be considered. See the Effect of Inrush Current on Sectionalizer Application section in this manual.

Coordination requirements

Two requirements must be met to assure coordination of Type GH hydraulically controlled sectionalizers with backup devices:

1. At the established maximum oil temperature (ambient plus rise), TAT must not exceed the value indicated by the sectionalizer coordination curve (Figure 8).

2. The fault current on-time (F2 + F3) cannot exceed 70% of the TAT allowed by the coordination curve for the maximum oil temperature expected.

Example 1

Conditions:

Max. ambient temperature 85 °F

Sectionalizer coil size 100 A

Normal load current 50 A

Backup OCR set for 1 fast, 3 delayed operations

Sectionalizer set for 3 counts to open

Maximum oil temperature: 85 + 13 = 98 °F

From the coordination curve in Figure 8, allowable TAT at 98 °F is 28 seconds. Figure 9 illustrates this example, and an explanation fol-lows.

To meet Coordination Requirement No. 2, the maximum current on-time (F2 + F3) for TAT of 28 seconds is 28 x 0.70 = 19.6 seconds (round off to 20 seconds.) Therefore, neither F2 nor F3 can exceed 20/2 or 10 seconds.

To meet Coordination Requirement No. 1, the TAT must not exceed 28 seconds. With F2 and F3 each 10 seconds, a maximum limit can be calculated for R1 and R2 as shown below.

TAT = (R1 + R2) = (F2 + F3)

R1 + R2 = TAT - (F2 + F3)

= 28 - (10 + 10)

= 8 seconds.

Therefore, the sum of the two reclosing times cannot exceed – but can be less than – 8 seconds.

Example 2

Conditions:

Max. ambient temperature 85°F

Sectionalizer coil size 100 A

Normal load current 50 A

Backup OCR set for 1 fast, 3 delayed operations

Sectionalizer set for 2 counts to open

Maximum oil temperature:

85 + 13 = 98°The allowable TAT is again at 28 seconds: with the sectionalizer set for two counts to open, there is only one fault current on-time (F2) and only one reclosing time (R1). Therefore, the fault current on-time (F2) cannot exceed 20 seconds, and the reclosing time (R1) must be 8 seconds or less.

Recloser-sectionalizer-fuse link coordination

If, for example, the backup device is set for a typical two-fast, two-delayed operating sequence, the sectionalizer counts twice on the first two operations of the recloser and, when the fuse blows on the first delayed operation of the recloser, counts the third time and opens. The sectionalizer counts the fuse clearing as the third fault-current interruption and erroneously isolates the section between it and the fuse link (Figure 10).

To properly coordinate a recloser, sectionalizer, and fuse link, the recloser must be set for one fast followed by three delayed opera-tions.

In Figure 11, the sectionalizer counts once on the recloser’s fast operation. The fuse blows while the recloser is timing its first delayed operation, and the sectionalizer registers its second count. The fault is removed and, with no further operation, the sectionalizer and recloser both reset.

Allowable TAT: 28 Seconds

Effect of inrush currents on sectionalizer application

One of the principal causes for unwanted and unexpected sectionalizer operation is inrush current, which is of two basic types: • cold-load pickup;• transformer magnetizing.

Although magnetizing current – determined by the connected kVA – is usually a greater factor than cold-load pickup, both types of inrush current must be considered when applying hydraulically controlled sectionalizers.

If, upon circuit energization, the current through the sectionalizer exceeds its actuating rating, the sectionalizer will arm to count immediately.

If the current then falls below 40% of the actuating rating, the sectionalizer will complete the count even though the backup protective device did not open (Figure 12).

However, for a fault on the source side of the sectionalizer, the backup device will trip. If, upon circuit re-energization, the inrush

current through the sectionalizer is greater than its actuating rating, the sectionalizer will arm to count. A second trip operation of the backup device will cause the sectionalizer to complete its count.

Determining effect of inrush current

To determine if the inrush current will exceed the actuating current rating of the sectionalizer, calculate the ratio of the actuating current rating of the sectionalizer to the peak load of the circuit. The lower the ratio, the higher the possibility of inrush current exceeding the actuating rating.

A. For ratios greater than 10, inrush currents will probably not be a factor in applying the sectionalizer.

B. For ratios between 10 and 5, inrush currents may be a factor. To ensure the actuating current rating is not exceeded, a more accurate determination must be made of the circuit parameters.

C. For ratios of 5 or less, inrush currents will in all probability exceed the actuating rating; unwanted sectionalizer operation can be expected.

DescriptionA sectionalizer is an automatic circuit opening device. After a circuit has been deenergized by a backup protective device - such as a recloser or recloser breaker - a sectionalizer isolates the faulted portion of a distribution line. After the fault has been isolated, the rest of the circuit is returned to service upon reclosure of the backup.

The sectionalizer counts the over-current interruptions of the backup and can be set to open after one, two, or three counts have been registered within a predetermined time span. A sectionalizer opens during the open interval of the backup. Although it cannot interrupt faults, it can be closed into them.

Sectionalizers can be used in place of fuses or between a reclosing device and a fuse. They only detect current interruptions above a predetermined level and have no time-current characteristics, permitting easy coordination with other protective devices on the system. They provide additional protection without adding a coordination step to the protective scheme.

Sectionalizers provide several advantages over fuse cutouts:• In addition to application flexibility, they offer

safety and convenience• After a permanent fault, the fault-closing

capability of the sectionalizer greatly simplifies circuit testing

• If a fault is still present, interruption takes place safely at the backup recloser

• Replacement fuse links are not required so the line can be tested and service restored with more speed, convenience, and economy

• Sectionalizers do not open accidently under load due to a damaged link

• The possibility of error in the selection of the correct fuse link size and type is eliminated

Sectionalizers provide an economical method to further improve service on distribution lines equipped with reclosers or reclosing circuit breakers by isolating permanent faults, thus confining outages to smaller sections of line.

Sectionalizers are applied on the load-side of the fault-interrupting device and count its fault-trip operations. The open during the first, second, or third open interval of the backup protective device, depending upon the coordination scheme selected. Sectionalizers are not designed to interrupt fault currents. They can, however, be closed in against a fault. The sectionalizer will forget counts that do not reach its counts-to-open setting due to clearing of temporary faults.

Types GN3E and GN3VE electronically controlled, manually closed sectionalizers

270-15-1

Technical Data 270-15Effective May 2014Supersedes January 1990

When properly applied, a sectionalizer will respond to downline fault currents that ate interrupted by its backup protective device. However, as with any other protective device, system conditions may product unexpected and unwanted sectionalizer operation.

Overcurrents interrupted by a downline protective device are one cause for these occurrences; inrush current is another. Count-restraint and inrush current restraint features are built into the electronic control to block the sectionalizer's response to these system conditions.

Summary of ratingsThe solid-state electronic control used in the Type GN3E and GN3VE three-phase sectionalizers provides accurate and reliable operation down to 16 amps on phase-fault and 3.5 amps on ground- (earth-) fault detection. Operation is unaffected over a wide range of ambient temperatures. Basic ratings are shown in Table 1.

The sectionalizer is self-contained. Current transformers- internally mounted on the bushings - provide power to operate the electronic control and the trip mechanism. Since these CTs obtain power from the line, no external source of auxiliary power is required.

The Type GN3E or GN3VE sectionalizer is a three-phase device that opens all three phases simultaneously for either a phase or ground fault or when used as a loadbreak switch. Three sets of oil-insulated contacts are connected by bellcranks to a common operating mechanism. A low-energy tripping mechanism-operated by the electronic control - initiates opening. Opening energy is provided by springs, charged when the sectionalizer is manually closed.

The sectionalizer senses overcurrent interruptions and opens after one, two, or three such interruptions have occurred. When a current above the reset actuating level of the sectionalizer is interrupted by a backup protective device, a count pulse is generated and registered in the electronic control. If the preset number of counts is registered within one minute, the sectionalizer will open during the open inter-

val of the backup device (when no current is flowing in the circuit).

The sectionalizer is completely self-contained. Power to operate the control and low-energy tripper is obtained from the line through bushing current transformers (mounted under the head) which sense the phase- and ground-fault currents. No auxiliary power supply is required.

The solid-state electronic control provides the operating logic for automatic opening. Closing is accomplished by manually closing the yellow operating handle under the sleet hood. The sectionalizer may also be manually opened with this handle which also provides a positive visual indication of contact position.

Surge protection

Sectionalizers operate best when protected with surge arresters. On line applications, arrester protection is recommended on both sides of the sectionalizer. If protection is to be provided on one side only, install the arrester on the source side. Eaton's Cooper Power Systems distribution-class arresters provide excellent protection; see Catalog 235-99, UltraSIL™ Polymer-Housed Evolution™ Surge Arresters.

Ordering informationWhen ordering a Type GN3E or GN3VE sectionalizer, include catalog number and description of basic sectionalizer and the phase and ground minimum-actuating-current plug-in resistors. A set (one each) of the phase and ground minimum-actuating-current plug-in resistors is included in the price of the basic sectionalizer. Also specify the operating settings for the inrush-current restraint. If accessories and/or mounting equipment are required, specify by catalog number and description.

Electronic controlA functional block diagram of the electronic control circuity is shown in Figure 2.

Bushing current transformers (BCT) sense the current flowing through the sectionalizer. Three transformers connected in a wye (star) configuration sense phase current. Three additional BCTs, connected in parallel, sense the ground- (earth-) or zero-sequence current. By selecting the proper plug-in resistors, these signals can be rectified and adjusted to the desired minimum actuating-current level.

To generate and register a count pulse, a current above the preset minimum actuating level must be flowing through the sectionalizer (downline fault). This overcurrent must drop to zero (fault interrupted by the backup protective device). The pulse counter provides storage for up to three pulses. Depending upon the counts-to-open setting, the tripping circuit will turn on after one, two, or three count pulses have been registered. When turned on, the tripping circuit completes the discharge path for the trip-energy-storage capacitors through the coil of the low-energy tripper which, in turn, trips the sectionalizer mechanism to open the sectionalizer contacts.

The pulse counter has a 60-second memory for each count. Thus, the preset number of counts must be registered within one minute for the sectionalizer to open. The control will reset (completely forget the registered count pulses that do not reach the preset number) within seven (7) minutes.

Types GN3E and GN3VE electronic sectionalizers contain a count-restraint feature. This feature prevents the sectionalizer from counting fault currents interrupted by a downline protective device. The current restraint will block the generation of a count pulse as long as at least 3-1/2 amps of load current are flowing through the sectionalizer after the fault current disappears.

The sectionalizer is also equipped with an inrush-current restraint feature which distinguishes between inrush current and fault current by a logic circuit functionally diagrammed in Figure 3.

If an overcurrent is present through the sectionalizer when the backup protective device opens (current is interrupted), the overcurrent present upon reclosing is assumed to be fault current and the sectionalizer control operates in its normal manner. If, however, there is no overcurrent detected by the sectionalizer when the current is interrupted, the overcurrent present upon reclosing is assumed to be inrush current. To prevent the sectionalizer from counting this inrush current, the fault-level detector circuit is modified to raise the phase-actuating level by a multiple of 2X, 4X, 6X, or 8X the normal setting (or current detection can be blocked entirely) for a time (Y) of 5, 10, 15, or 20 cycles after current flow through the sectionalizer is restored. After this time, the sectionalizer control returns to normal operating settings. At the

same time, ground overcurrent detection is blocked entirely for a period (Z) of 0.3, 0.7, 1.5, 3, or 5 seconds after current flow through the sectionalizer is restored.

On multi-grounded-wye systems, the entire transient inrush of a particular phase could flow in the neutral. Typical settings for ground-fault sensing on these systems is one-half or less of phase-fault sensing. This could result in values at lease twice those necessary for phase magnitude and duration (X and Y). With the improved ground-inrush logic, ground sensing is simply blocked for the duration of the Z selected.

Trip-energy storage capacitors

The control is powered by the load and/or fault current flowing through the sectionalizer. This also charges the trip-energy-storage capacitors. For most cases, the charging time of the capacitors (Figure 4) is less than the clearing time of the three-phase reclosers from Eaton's Cooper Power Systems with which the GN3E and GN3VE sectionalizers are specifically intended to coordinate. Some recloser fast-trip curves may have a faster clearing time at their low end than the capacitor charging time. These exceptions are listed in Table 8 (Phase Trip Coordination) and Table 9 (Ground Trip Coordination).

To verify proper coordination between the sectionalizer and its backup protective device, the charge time of the trip-energy-storage capacitors (Figure 4) can be plotted against the clearing-time curve of the backup device. Note that the capacitor charge-time curve is plotted in amps, not in % of minimum actuating current.

Count-restraint feature

The count-restraint feature blocks the sectionalizer from generating a count pulse as long as some load current flows through the sectionalizer. Thus, the sectionalizer does not count or operate when a load-side device interrupts the overcurrent.

Figure 5 show a typical application with the sectionalizer located between two reclosers.

For a fault (F1) beyond the load-side recloser (ACR2), only the load-side recloser operates. The sectionalizer does not generate a count because the load current through the sectionalizer is not interrupted. For a load-side fault (F2) interrupted by the souce-side recloser (ACR1), the sectionalizer counts the fault interruption since the load current through the sectionalizer is interrupted.

The count-restraint feature is designed to operate with a minimum of 3-1/2 amps load current through the sectionalizer. It is a standard feature of all GN3E and GN3VE electronically controlled sectionalizer.

Inrush-current restraint feature

One of the principal causes for unwanted sectionalizer operation is inrush current. If the backup device interrupts a fault on the down-line side of the sectionalizer, the sectionalizer will generate and reg-ister a count pulse in the normal manner. If the fault is interrupted by a downline protective device, the count-restraint feature will block the generation of a count pulse if at least 3-1/2 amps of uninter-rupted load current flows through the sectionalizer.

For a fault on the source-side of the sectionalizer (Figure 6), the backup device will trip and deenergize the circuit. However, if upon circuit renergization, the inrush current through the sectionalizer is greater than its minimum actuating current setting, a second trip operation of the backup device will defeat the count-restraint feature (load current is interrupted) and cause the sectionalizer to generate and register a count.

The inrush-current restraint feature distinguishes between inrush current and fault current by means of a logic circuit previously described. It prevents false counting and operation of the sectionalizer due to inrush currents through the sectionalizer during operation of the source-side protective device.

Low-energy tripping mechanism

The low-energy tripping mechanism operated from the electronic control, initiates the automatic-opening operation. The mechanism consists of a permanent magnet, and a solenoid and coil assembly

which operate a trip lever (Figure 7).

When the sectionalizer is closed, the solenoids's plunger is held by the magnetic force produced by the permanent magnet. In this position, the compressed spring is acting to release the plunger.

During the opening operation, the trip-energy-storage capacitors are connected across the coil of the solenoid. The counter-magnetic flux

produced by the discharge of the capacitors is great enough for the compressed spring to override the net magnetic force, pull down the plunger to operate the trip lever, and open the sectionalizer contacts. As the sectionalizer contacts are opened, the spring-biased reset lever of the tripping mechanism is released to return the solenoid plunger and reset the assembly for the next opening operation.

Application requirementsThe following basic coordination principles should be observed in the application of Types GN3E and GN3VE electronically controlled sectionalizers:

1. For both phase and ground currents, the minimum actuating-current setting of the sectionalizer should be approximately 80% of the minimum trip-current setting of the backup recloser or recloser breaker.

2. The counts-to-open setting of the sectionalizer must be at least one less than the number of operations to lockout of the backup device.

3. Total accumulated time (TAT) for the operation of the backup fault-interrupting device must not exceed one minute between each operation. TAT is counted from the backup device's first trip operation to the trip operation which causes the sectionalizer to open.

4. To assure that the trip-energy-storage capacitors are fully charged before the backup trips, the clearing time of the backup device must be greater than the charging time of the trip-energy-storage capacitors. The charging time-current curve for the trip-energy-storage capacitors is shown in Figure 4.

5. To operate the count-restraint feature, a minimum of 3-1/2 amps of load current must normally flow through the sectionalizer.

6. The momentary and short-time ratings of the sectionalizer must not be exceeded.

7. Three-phase sectionalizers must be used with backup breakers or reclosers in which all three phases open simultaneously. The counting functions of the sectionalizer do not recognize a signal as originating in a particular phase, but total the overcurrent interruptions in all three phases. Non-simultaneous three-phase tripping of the backup device could result in the sectionalizer

interrupting fault current in one or more phases.

8. Application on multi-grounded-wye systems generally required ground-fault sensing and inrush-current restraint. Setting the phase actuating level to the ground setting of the backup device may result in erroneous counts due to inrush currents and incor-rect opening of the sectionalizer for source-side faults.

Application of inrush-current restraint

Sectionalizers can be applied where the main feeder is divided into two feeders close to the substation (Figure 8). Inrush current will be a problem here, since the load current (and connected transformer capacity) if close to the operating settings of the sectionalizer.

A sectionalizer may also be applied to protect an important branch which may be carrying only a small portion of the total load (Figure 9). Although this example will result in fewer inrush-current problems than the previous application, inrush-current considerations should not be ignored here.

The typical sectionalizer settings shown in these illustrations are identical for both applications since they are based on the settings of the backup device.

To prevent false operation, the inrush-restraint function should be programmed so that:

1. The Multiplier setting exceeds the expected inrush current (cold-load pickup and/or transformer magnetizing);

2. The inrush current decays to below the normal actuating current setting of the sectionalizer within the duration of the Reset setting.

Sectionalizer settingsFor proper sectionalizer operation, the following settings must be specified on the order: • Minimum phase-actuating current• Minimum ground-actuating current• Number of overcurrent counts to open• Multiple of phase minimum-actuating current• Duration of raised phase current sensing• Duration of ground current-sensing block

Minimum-actuating current

To assure that the sectionalizer will sense and count every fault-trip operation of its backup protective device, the minimum-actuating phase- and ground-trip setting should be approximately 80% of the comparable minimum-trip values of the backup device. However, in a few instances, the lower end of the back-up recloser's fast-trip curve may be faster than the charging time of the trip-energy-storage capacitor, and proper coordination may not be attained.

The minimum-trip levels of the recloser fast curves in question and the comparable minimum-actuating levels of the sectionalizer to attain proper coordination are listed in Tables 8 and 9. Below these levels, the Type GN3E and GN3VE sectionalizer may not count the fast-curve operation.

The minimum actuating-current level is determined by plug-in resistors located on the inrush-current-restraint circuit board housed in the control cabinet (Figure 10).

The available minimum actuating-current-level values for both phase and ground have been selected to coordinate with the more popular recloser trip settings. The following values are available for phase sensing: 16, 24, 40, 56, 80, 112, 160, 224, 256, 296, and 320 amps. For ground sensing, the values available are 3.5, 5, 7, 16, 28, 40, 56, 80, 112, 160, 224, and 320 amps.

Note: If the backup protective device does not include ground-fault trip, a dummy plug-in resistor is used to deactivate the ground-sensing circuits of the sectionalizer control. See Ordering Information for proper catalog number.

Number of counts to open

The number of overcurrent counts to open should be at least one less than the number of trips to lockout of the backup device. One, two, or three counts are available.

This setting is determined by attaching the jumper wire to the proper terminal tab on the same printed-circuit board that holds the phase and ground plug-in resistors (Figure 10).

Inrush-current restraint Whenever circuit logic determines that the over-current is inrush current, this feature raises the minimum phase-actuating-current level of the sectionalizer by a multiple X (2, 4, 6, or 8 times) or blocks overcurrent detection entirely for a period of time Y (5, 10, 15, or 20 cycles) after current flow through the sectionalizer is restored. At the same time, ground overcurrent detection is also blocked entirely for a period Z (0.3, 0.7, 1.5, 3, or 5 seconds). To operate effectively, the values selected for X, Y, and Z should exceed the time-current parameters of the expected inrush currents.

With the inrush-current restraint set on BLOCK for phase-sensing and the ground-sensing circuit normally operating on block, the sectionalizer will not count a system fault interrupted by the backup device within the block time span.

The settings for raising the phase-current-actuating level, the dura-tion of this raised level, and the duration of ground-current block are made by attaching jumper wires to the proper terminal tabs on the inrush-current-restraint circuit board. This circuit board is housed in the control cabinet at the back of the sectionalizer (Figure 10).

Sectionalizers are automatically controlled circuit-opening devices which isolate a faulted portion of a circuit after the circuit has been deenergized by a primary protective device, such as a recloser or reclosing circuit breaker. After the fault has been isolated, the rest of the circuit can be returned to service.

Design and application A sectionalizer cannot interrupt faults but can be closed in against them without being damaged. It senses the overcurrents which are interrupted by the backup protective device and will open during the first, second, or third open interval of the circuit. Since the sectionalizer does not require a time-current base for its operation, it is easily coordinated with other protective devices on the system. It provides an additional step of protection without adding a coordinating step to the protective scheme.

Because it has no time-current characteristic, a sectionalizer has distinct application advantages. • It can be applied between two protective

devices having operating curves which are close together. This is a vital feature in a location where an additional step in coordination is not practical or possible.

• It can be used on close-in taps where high available fault current prevents coordination with fuses.

Sectionalizers provide several advantages over fuse cutouts. In addition to application flexibility, they offer safety and convenience. After a permanent fault, the fault-closing capability of the sectionalizer greatly simplifies testing the circuit and, if the fault is still present, interruption takes place safely at the backup recloser. Replacement fuse links are not required; thus the line can be tested and service restored with far more speed, convenience, and economy. Also the possibility of error in the selection of the right size and type of replacement fuse link is eliminated.

To improve service continuity and provide more reliable coordination with backup protective devices, the Type GV and GW sectionalizers include the following operating features:

Ground-fault sensing – enables the sectionalizer to coordinate with ground fault tripping reclosers or breakers.

Inrush-current restraint – prevents false counting due to inrush currents that may occur when a circuit is reenergized.

Count-restraint – prevents counting overcurrents interrupted by downline protective devices.

Count reset – provides fast reset of the sectionalizer count memory after successful circuit recloser to better coordinate with backup protective devices.

Ordering information When ordering Type GV or GW sectionalizers, include catalog number and description of basic sectionalizer and the phase and ground minimum-actuating-current plug-in resistors. Also specify the operating settings of the sectionalizer If accessories and/or mounting equipment are required, specify by catalog number and description.

Figure 1. External features of electronically controlled sectionalizer.

Features and detailed descriptionSectionalizers are an economical method of further improving service on distribution lines equipped with reclosers or reclosing circuit breakers. They isolate permanent faults and confine outages to smaller sections of line.

Sectionalizers are applied on the load side of a fault-interrupting device and count its fault-trip operations. They open during the first, second, or third open interval of the fault-interrupting device, depending upon the coordination scheme selected. Sectionalizers are not designed to interrupt fault currents. They can, however, be closed in against a fault. The sectionalizer can forget counts that do not reach its counts-to-open setting due to clearing of temporary faults.

When properly applied, a sectionalizer will respond to downline fault currents that are interrupted by its backup protective device. However, as with any other protective device, system conditions may produce unexpected and unwanted sectionalizer operation. Overcurrents interrupted by a downline device are one cause for these occurrences; inrush current is another. Count restraint and inrush-current-restraint features are built into the electronic control to block the sectionalizer’s response to these system conditions.

All three phases of the sectionalizer are actuated by a common shaft connected to an actuator located in an external cabinet which also

houses the control. In both Type GV and GW sectionalizers, fault currents are sensed by internally mounted,1000:1 ratio, bushing-type current transformers.

Phase and ground minimum-actuating-current levels are determined by individual plug-in type resistors. All other operating parameters are selected by means of programmable selector switches located on the control circuit board.

Description of operation Mechanical operation

The sectionalizer consists of three sets of oil-insulated contacts linked with bell-cranks to a common shaft which is connected to the mechanism housed in the operator cabinet. Opening is initiated by a low-energy tripper mechanism operated by the electronic control. Actual opening energy is provided by springs which are charged when the sectionalizer is manually closed. Closed and open positions are indicated by a red pointer-like flag; contact opening operations are registered on a three-digit counter both are located under the sleet hood of the operator cabinet.

The sectionalizer is manually closed by pulling down the spring-biased, gray, pull ring 12 to 14 times with a hookstick (Figures 5 and 7). The sectionalizer can be manually opened by operating the yellow pull ring once (Figures 5 and 6). Both rings are clearly labeled. The sectionalizer can be programmed to open on the first overcurrent count by pulling down the one-count-to-open lever located underneath the operator cabinet between the two pull rings (Figures 5 and 8).

Electronic control operation A functional block diagram of the electronic circuitry is shown in Figure 9.

Current flowing through the sectionalizer is sensed by the bushing-current transformers. Three transformers connected in a wye (star) configuration sense phase currents. Another three bushing-current transformers connected in parallel sense the ground (earth) or zero-sequence current. These signals are rectified and are adjusted to the desired minimum-actuating-current level by the selection of the proper plug-in resistors.

To generate and register a count pulse, a current above the preset-minimum-actuating level must be flowing through the sectionalizer (downline fault) and this overcurrent must drop to zero (fault interrupted by the backup protective device). The pulse counter provides storage for up to three pulses. Depending upon the counts-to-open setting, the tripping circuit will turn on after one, two, or three count pulses have been registered. When turned on, the tripping circuit completes the discharge path for the trip-energy-storage capacitors through the coil of the low energy tripper which, in turn, trips the sectionalizer mechanism to open the sectionalizer contacts.

The pulse count reset will erase any stored pulse counts whenever load current through the sectionalizer flows without interruption for longer than the reset time programmed.

A count-restraint feature is built into the control of Types GV and GW sectionalizers to prevent the sectionalizer from counting fault currents interrupted by a downline protective device. The current restraint will block the generation of a count pulse as long as at least 5 amps of load current is flowing through the sectionalizer after the

disappearance of fault current.

The control is also equipped with an inrush-current restraint feature which distinguishes between inrush current and fault current by a logic circuit functionally diagrammed in Figure 10.

If an overcurrent is present through the sectionalizer when the backup protective device opens (current is interrupted), the overcurrent present upon reclosing is assumed to be fault current and the sectionalizer operates in the normal manner as previously described. If, however, there is no overcurrent detected by the sectionalizer when the current is interrupted, the overcurrent present upon reclosing is assumed to be inrush current. To prevent the sectionalizer from counting this inrush current, the fault level detector circuit is modified to block the phase and ground actuating levels for a time of three seconds after current flow through the sectionalizer is restored. Upon expiration of this time, the sectionalizer control returns to normal operating settings.

The control is powered by the load and/or fault current flowing through the sectionalizer which also charges the trip energy stor-age capacitors. For most cases the charging time of the capacitors (Figure 11) is less than the clearing time of Eaton's Cooper Power Systems three-phase reclosers with which the GV-GW sectional-izers are designed to coordinate. Some recloser fast trip curves may have a faster clearing time at their low current end than the capaci-tor charging time. These exceptions are listed in Table 3 (Phase Trip Coordination) and Table 4 (Ground Trip Coordination).

For these exceptions a voltage charging feature is built into the sectionalizer control as standard which requires a 120-Vac auxiliary power source (25 w min). The potential charger will fully charge the trip capacitor in less than 25 milliseconds (approximately 1-1/2 cycles).

Proper coordination between the sectionalizer and its backup protective device can be verified by plotting the charge time of the trip-energy-storage capacitors (Figure 11) against the clearing time curve of the backup device. Note that the capacitor charge time curve is plotted in amps, not percent of minimum trip.

Voltage-restraint feature

When energized at 120 Vac, the voltage charging board provides fast charging times for the trip energy storage capacitors. It also acts as a voltage restraint; the sectionalizer will not count an overcurrent interruption of the protective device unless the voltage at the control is also interrupted.

270-20-8



www.cooperpower.com

Count-restraint feature

The count-restraint feature blocks the sectionalizer from generating a count pulse as long as some load current flows through the sectionalizer. Thus the sectionalizer does not count or operate when a load-side device interrupts the overcurrent.

In a typical application, the sectionalizer is located between two reclosers as shown in Figure 12.

For a fault (F1) beyond the load-side recloser (ACR2), only the load-side recloser operates. The sectionalizer does not generate a count because the load current through the sectionalizer is not interrupted. For a load-side fault (F2) interrupted by the source-side recloser (ACR1) the sectionalizer counts the fault interruption since the load current through the sectionalizer is interrupted.

The count-restraint feature is designed to operate with a minimum of 5 amps load current through the sectionalizer. It is a standard feature of Types GV-GW electronically controlled sectionalizers.

Inrush-current-restraint feature

A principal cause for unwanted sectionalizer operation is inrush current. For a fault on the downline side of the sectionalizer interrupted by the backup device, the sectionalizer will generate and register a count pulse in the normal manner. If the fault is interrupted by a downline protective device, the count-restraint feature will block the generation of a count pulse if at least 5 amps of uninterrupted load current flows through the sectionalizer.

For a fault on the source side of the sectionalizer (Figure 13), the backup device will trip and deenergize the circuit. However, if upon circuit reenergization, the inrush current through the sectionalizer is greater than its minimum-actuating-current setting, a second trip operation of the backup device will defeat the count-restraint feature (load current is interrupted) and cause the sectionalizer to generate and register a count.

The inrush-current-restraint feature distinguishes between inrush current and fault current by means of a logic circuit previously described under Electronic Control Operation. It prevents false counting and operation of the sectionalizer due to inrush currents through the sectionalizer during operation of the source-side protective device for faults on other parts of the circuit.

Response-time feature

For backfed motor contribution and unsymmetrical clearing of upline faults, a response time is built into the sectionalizer control to eliminate unwanted counting of these situations. Upon detection of any current above the phase or ground actuating setting, the current must exceed the response-time characteristics as illustrated in Figure 14. Total clearing time of reclosers and breakers must exceed the response time characteristic of the sectionalizer.

Application requirementsThe following basic coordinating principles should be observed in the application of the electronically controlled sectionalizer.

1. The minimum actuating current setting of the sectionalizer should be no greater than 80 percent of the minimum trip current setting of the backup recloser or reclosing breaker for both phase and ground currents.

2. The counts-to-open setting of the sectionalizer must be at least one less than the number of operations to lockout of the backup device.

3. The count reset time of the sectionalizer control must be greater than the reset time of the backup protective device.

4. The minimum clearing time of the backup device must be greater than the charging time of the trip-energy storage capacitors to assure that the capacitors are fully charged before the backup trips. See Minimum Actuating Current.

5. To operate the count-restraint feature, a minimum of 5 amps of load current must normally flow through the sectionalizer.

6. The momentary and short time ratings of the sectionalizer must not be exceeded.

7. Three-phase sectionalizers must be used with backup breakers or reclosers in which all three phases open simultaneously. The counting functions of the sectionalizer do not recognize a signal as originating in a particular phase, but totals the overcurrent interruptions in all three phases. Nonsimultaneous three-phase tripping of the backup could result in the sectionalizer interrupting fault current in one or more phases.

8. Application on multigrounded wye systems generally requires ground fault sensing and inrush-current-restraint. Setting the phase actuating level to the ground setting of the backup device may result in erroneous counts due to inrush currents and incorrect opening of the sectionalizer for source-side faults.

9. Ground fault actuating settings should be set at or above peak loading at the sectionalizer location. This will prevent sectionalizer sensing system unbalance during upline phase-to-ground faults which generate system imbalances.

Application of inrush-current-restraint

Sectionalizers can be applied where the main feeder is divided into two feeders close to the substation as shown in Figure 15.

Here, loads are likely to be reasonably equally divided. Sectionalizers may also be applied to protect an important branch which may be carrying only a small portion of the total load as shown in Figure 16.

The inrush current restraint has been designed to provide optimum protection from in-rush currents. No settings are required as pick-up values will be blocked during inrush conditions. This allows flexibility in the application without concern for increased connected loading on the system.

The sectionalizer is blocked for three seconds to allow for decay of magnetizing inrush, system imbalance, and initial inductive loading after long reclose intervals.

Sectionalizer settings For proper operation the following operating settings must be specified.

1. Minimum-phase-actuating current.

2. Minimum-ground-actuating current.

3. Number of counts to open.

4. Reset time.

All operating settings are programmed on the control circuit board in the operator mechanism cabinet (Figure 17).

Minimum actuating current

To assure that the sectionalizer will sense and count every overcurrent trip operation of its backup protective device, the minimum actuating current settings for phase and ground should be approximately 80% of the comparable minimum trip values of the backup device. However, in a few instances the lower current end of the backup recloser’s fast trip curve may be faster than the charging time of the trip energy storage capacitor and proper coordination may not be attained.

The minimum trip levels of the recloser fast curves in question and the comparable minimum actuating levels at which recloser-sectionalizer coordination can be attained are listed in Tables 3 and 4. Below these levels the sectionalizer may not count the fast trip operations.

Coordination below the levels shown in Tables 3 and 4 can be achieved by energizing the potential capacitor charger. With 120-Vac auxiliary power supplied to the sectionalizer, the trip capacitors are fully charged in less than 25 milliseconds (approximately 1-1/2 cycles). The potential capacitor charger, and its 120-Vac input plug and receptacle are standard features of the sectionalizer.

The minimum-actuating-current level is determined by plug-in resistors on the printed circuit board of the electronic control (Figure 17).

The available minimum actuating current level values for both phase and ground have been selected to coordinate with the more popular recloser trip settings. For phase sensing, the following values are available: 16, 24, 40, 56, 80, 112, 160, 224, 256, 296, 320, 448, 480, and 640 amps. For ground sensing, the following values are available: 3.5, 7, 16, 20, 28, 40, 56, 80, 112, 160, 224, and 320 amps. Each resistor is labeled and its function (phase or ground) and with its minimum trip rating in amps.

otee:N If the backup does not include ground fault tripping, a dummy plug-in resistor, labeled BLOCK, is used to deactivate the ground sensing circuit of the sectionalizer control. See ordering Information for proper catalog number.

Number of counts to open

The number of counts to open the sectionalizer should be no more than one less than the number of trips to lockout of the backup device. One, two, or three counts are available. This setting is determined by the position of the COUNTS TO OPEN selector switch (Figure 17).

Count reset

This feature resets to zero any accumulated counts whenever cur-rent below the minimum trip level flows through the sectionalizer uninterrupted for longer than the programmed time. Count reset will operate with any current flow from minimum load (5 amps) to minimum actuating. To properly coordinate with its backup, the count reset time selected must be greater than the reset time of the backup.

Reset times of 15, 30, 60, 90, 120 and 180 seconds are available. This setting is determined by the position of the COUNT RESET selector switch (Figure 17).

otee:N The count will also reset to zero whenever the sectionalizer is opened either manually or automatically.

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 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 .

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



© 2013 EatonAll Rights ReservedPrinted in USAPublication No. 280-05August 2013


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


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.

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.

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 .

Control featuresControl security

The SPEAR single-phase recloser control has multiple customer-programmable security codes to limit control programming and viewing function access to authorized personnel . The SPEAR control is capable of supporting numeric passwords . 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 SPEAR 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 port . Each protection profile contains overcurrent protection and operation settings .

Reclosing and overcurrent protection/TCCs

The SPEAR control offers flexible phase 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-four standard curves which can be further customized . 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 .

280-101-14



www.cooperpower.com

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 .

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.

280-104-6



www.cooperpower.com

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.

Figure 2. Contact I/O module option.

• 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

DescriptionThe Type VSA20B electronically controlled, vacuum circuit breaker provides reliable and economical overcurrent protection for 15 kV distribution systems.

The VSA20B circuit breaker has been full-power tested in accordance with ANSI® and NEMA® standards for power circuit breakers. Detailed ratings and related capabilities on a symmetrical current basis, using maximum design voltage and a K factor of 1.0, are shown in Table 1.

The VSA20B circuit breaker has a rated interrupting time of 2.5 cycles in accordance with ANSI® stan-dards. The fast interrupting time minimizes fault damage and provides fast coordination capability.

A choice of electronic 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 VSA20B circuit breaker provides service-proven dependability and long operating life.

Commanded by an Eaton's Cooper Power Systems electronic control, this automatic circuit breaker offers superior coordination and application capability, unmatched by other system protection apparatus.

Breaker 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. Breaker and control accessories enable further tailoring of the protective program to achieve maximum system operating flexibility.

When needed, application expertise, backed by world wide application experience, is readily available. Eaton's Cooper Power Systems design capability is based on over 50 years of switchgear manufacturing experience. Progressive product development programs, using the latest technologies, have resulted in the production of modern, efficient breakers from Eaton's Cooper Power Systems.

VSA20B circuit breakers are designed and built in accordance with ANSI/IEEE C37.04-1979, ANSI C37.06-1987, ANSI/IEEE C37.09-1979, and ANSI/IEEE C37.012-1979.

Type VSA20B air-insulated; vacuum; electronically controlled power circuit breaker

290-25-1


RatingsThe Type VSA20B circuit breaker can be applied on distributions systems ranging from 2.4 through 14.4 kV. Standard duty cycle is; CO-15 seconds-CO. Basic ratings are shown in Table 1.

Characteristic featuresFault-sensing information for VSA20B circuit breakers is supplied to the electronic control by bushing-type current transformers mounted in the circuit breaker. Tripping and closing signals from the control energize operating circuits in the circuit breaker.

Minimum-trip values of the control are independent of the continuous current and interrupting ratings of the circuit breaker. 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 circuit breaker by charging the closing springs, which in turn provides the force to close the vacuum interrupters and charge the opening springs.

Eaton's Cooper Power Systems vacuum interrupters have had an excellent field reliability record since their initial introduction in 1966 in the most complete line of vacuum switchgear available in the industry.

Mounting equipmentVSA20B circuit breakers are furnished in standard frames with corner lifting eyes. Mounting equipment is available for substation installation of the circuit breaker (see Table 6 for mounting accessories).

Surge protection Best operating results are achieved when circuit breakers are protected with surge arresters. 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, UltraSIL™ Polymer-Housed VariSTAR™ Surge Arresters and 235-99, UltraSIL Polymer-Housed Evolution™ Surge Arresters.

Circuit breakerVSA20B circuit breakers feature vacuum interruption with air insulation and low-voltage motor operation. VSA20B circuit breakers are designed for circuit protection on systems operating through 14.4 kV.

Because of the large selection of trip ratings and the flexibility provided by Eaton's Cooper Power Systems electronic controls, VSA20B circuit breakers can be applied to meet a wide variety of requirements.

The vacuum interrupters in VSA20B circuit breakers 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 circuit breakers. Vacuum interruption also provides greater safety for indoor applications than arc interruption in oil.

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

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

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

ConstructionEaton's Cooper Power Systems air-insulated vacuum circuit breakers offer extra-long service life and require minimal maintenance. Vacuum interrupter contacts, as well as the entire circuit breaker, 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 circuit breaker.

Vacuum interrupters are mounted independently of the bushings. The bushing rods clamp to a current transfer member of the inter-rupter 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.

Motor operation

VSA20B air-insulated, vacuum circuit breakers employ a 240 Vac, motor-driven operating mechanism to charge closing and opening springs.

Tripping

Circuit breaker tripping employs stored spring energy. When line cur-rent exceeds the programmed minimum-trip value, in one or more phases, the control energizes a trip solenoid in the operating mecha-nism. The solenoid trips a latch which releases a spring-loaded toggle assembly, opening the circuit breaker contacts and a switch which interrupts the 24-volt signal from the control. Maximum clearing time is 2 1¼2 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 auto-matically operated to keep the closing springs in a charged state.

To close the circuit breaker, the control initiates a signal which ener-gizes a solenoid in the circuit breaker 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 circuit breaker lose 240 Vac motor supply voltage while the closing spring is charged and contacts are closed, an Open-Close-Open sequence remains stored in the circuit breaker operating mechanism. If the circuit breaker 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 circuit breaker always contains energy for at least one trip operation.

www.cooperpower.com

Manual operationA closed circuit breaker 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 Pullring. When the circuit breaker is manually tripped, the closing circuit is opened to prevent reclosing. The circuit breaker can be manually restored to service by placing the RESET-TRIP knob at RESET and moving the manual control switch on the circuit breaker control to CLOSE. The manual control switch on the circuit breaker control panel can also be used for tripping.

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

An emergency means is provided to manually close a VSA20B circuit breaker 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 VSA20B circuit breakers are manufactured exclusively at Eaton's Cooper Power Systems Switchgear plant. Our 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 circuit breaker.

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 our 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.

Choice of electronic circuit breaker controlsThe operation of a VSA20B circuit breaker is commanded by an electronic control from Eaton's Cooper Power Systems. We offer a choice of two controls that can be used in conjunction with these circuit breakers. This permits the user to select the control that best fits the requirements of each application.

Form 4C microprocessor-based controlThe Form 4C microprocessor-based control, shown in Figure 6, incorporates computer technology to provide enhanced application versatility and ease of operation.

The Form 4C primary source of power is 120 Vac or 240 Vac (customer supplied).

All standard control operating parameters including phase- and ground-fault minimum trip levels, time-current curve selection, and sequence of circuit breaker 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 interrogation and 10 front panel LCD indicators provide control and circuit breaker status, at a glance.

A front panel data port is provided to permit temporary connection to a data reader for downloading control data files, or for temporary connection to a personal computer for uploading or downloading control programming information and stored data.

Figure 4. Vacuum interrupters are used in VSA20B circuit breakers.

Figure 5. Form 4C microprocessor-based control.

290-25-6



www.cooperpower.com

The control is equipped with 41 keyboard-selectable time-current curves which are interchangeable for either phase or ground. Each of the curves can be custom modified to provide 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, event recorder, circuit breaker duty monitor, demand metering, and load profile monitor.

The microprocessor-based control can be equipped with an accessory supervisory input/output board to extend the supervisory operation capabilities of the control. A fiber optic digital communications accessory is also available for distribution automation applications.

FXA microprocessor-based control

The FXA microprocessor-based recloser control provide the operational intelligence for three-phase electronically controlled reclosers. The control is equipped with features that provide application flexibility, metering, and event recording.

The FXA primary source of power is 120 Vac or 240 Vac (customer supplied).

The FXA control makes use of a unique Microsoft® Windows®-based application to program and interrogate the controls. Connection to a computer is made via a front panel EIA232 port for easy customer access.

The FXA control can be ordered with supervisory I/Os for remote operation (SCADA option).

The control interface application makes it possible to upload operating parameters to the control as well as download present operating parameters from the control and collected data from the control data bases. Operating parameters and collected data can be saved to disk, for future reference or to provide system documentation.
