DescriptionGeneral
3AD vacuum reclosers are outdoor circuit-breakersdesigned for frequent opening and reclosing in case oftemporary faults. They fulfill this task automatically bymonitoring the line and operating autonomously.
The recloser consists of two main components: Theswitch unit being the circuit-breaker and the controller asprotection and control unit. It is housed inside the controlcubicle.

Recloser principle
Reclosers are used in distribution systems of power supplycompanies (utilities). Like circuit-breakers they are capableof switching normal and fault currents. They are equippedwith sensors and a controller being the protection andcontrol device. In case of a line fault, they can break andmake several times, thus avoiding longer network interrup-tions due to temporary faults.
As outdoor devices they are normally pole-mounted andexposed to environment and weather. A recloser consists oftwo components: The switch unit (circuit-breaker) and thecontroller (inside the control cubicle), both connectedthrough a control cable.
Design
Switching operationThe vacuum switching technology, proven and fullydeveloped for more than 30 years, is the basis for thevacuum interrupters.
Pole assemblies
Each vacuum interrupter is embedded in an epoxy-resin polemade out of weather-proof cycloalyphatic resin. This enablesa small design as well as resistance against environmentaleffects. The vacuum interrupter is vertically mounted insidethe pole, providing a long service life. Each recloser is equip-ped with an integrated current transformer. For special pro-tection purposes, a resistive voltage sensor can also beincorporated in the pole. The accuracy achieved in this wayis much higher than that of capacitive dividers.
Operating mechanism
The pole assemblies of the recloser are directly mounted onthe operating mechanism housing. Besides the completekinematics, it also accommodates the position indicator anda mechanical operations counter. The operating mechanismhousing is made of mild steel with a special coating for out-door applications. Optionally, a stainless-steel housing isavailable.
The recloser is installed on the pole by means of a polemounting frame. Alternatively, the recloser can be mounteddirectly on a frame for pad-mounting in substations.
Magnetic actuator
The recloser is operated by a magnetic actuator enabling therecloser cycle, i.e. the high number of switching operationswithin a short period of time. The actuator is a bi-stablesystem, locked in the end positions by permanent magnets.If not in operation, the magnet coils do not consume anypower. The operating force is transmitted to all three polesthrough a mechanical coupling.

Siemens Vacuum Recloser 3ADDescriptionSwitch unit
Mechanical lockout
A mechanical lockout enables tripping independently on thecontroller. If this handle is pulled, the recloser opens and issimultaneously locked out electrically and mechanically. Thehandle stays extended, thus indicating the interlocked state.
To close the recloser again, the operating rod must first bepushed back to the operation position in order to release thelockout. Then the recloser can be closed electrically via thecontrol.
Recloser cycle
In case of a network fault, the recloser opens and reclosesseveral times. In case of temporary faults the automaticreclosing significantly reduces the loss of power supply.The recloser cycle is optimized accordingly:
• The first interruption of a fault is done quickly andinstantaneously, so that even the fuses in the system do notoperate. After approx. 300 ms (user settable), it reclosesback on.
• The second and third interruption has a definite or inverse-time delay. Thus, downstream fuses in the network have thechance to operate and isolate the affected network section,restoring normal operation in the remaining network. Thefollowing dead time is usually 2–10 s (user settable).
• The fourth (optional up to the fifth) interruption is fastagain and serves as a check. This for example utilizes thephysical effect that, when the short-circuit occurs, the linesmove due to the magnetic forces of the current, and foreignobjects are “shaken off”.
• If the fault still exists, the recloser turns to the lockout andcan only be closed from the operator panel or via SCADA.

The controller
The Siemens Argus-M controller is based on the Argus-Mdirectional overcurrent protection relay. These relays provideprotection, control, monitoring, instrumentation and me-tering with integrated input and output logic, data logging& fault reports.
Communication access to relay functionality is via a frontUSB port for local PC connection or a rear electrical RS485port for remote connection. Additional rear port options areavailable.
The controller is mounted in the control cubicle. Along withthe controller, this cubicle also contains the auxiliary powersupply with batteries for uninterruptible power supply,electronic boards, fuses, and a general-purpose outlet topower a laptop.
The controller contains a large number of protectionfunctions (elements) which can be selected or deselectedthrough the menu driven display. These elements can becustomized to the utilities’ needs by parameters (settings) asdescribed below.
User interface
• 20-character x 4-line backlit LCD
• Menu navigation keys
• 3 fixed LEDs
• 8 or 16 programmable tri-color LEDs are availableeliminating the need for expensive panel-mounted pilotlights and associated wiring. Each LED is tri-colored (red,green, yellow) allowing for clear indication of the associatedfunction’s state.
• 12 programmable function keys each with tri-color LED areavailable for implementing scheme control functionality.
• Each function key has an associated tri-color LED (red,green, yellow) allowing for clear indication of the associatedfunction’s state.

Protection functions(in order of ANSI numbering)
37 Undercurrent
Each element has settings for pickup level and Definite TimeLag (DTL) delays. Operates if current falls below setting forduration of delay.
46BC Broken conductor/phase unbalance
Element has settings for pickup level and DTL delay. With thecircuit-breaker closed, if one or two of the line currents fallbelow setting, this could be due to a broken conductor.
46NPS Negative phase-sequence overcurrent
Each element has user settings for pickup level and InverseDefinite Minimum Time Lag (IDMTL) or DTL delay. It operatesif NPS current exceeds setting and delay. NPS current ele-ments can be used to detect unbalances on the system orremote earth faults when a delta-star transformer is incircuit.
49 Thermal overload
The thermal algorithm calculates the thermal states from themeasured currents and can be applied to lines, cables andtransformers. Outputs are available for thermal overload andthermal capacity.
50/51 Phase fault
50 INST (instantaneous)/DTL (Definite Time Lag) and51 IDMTL (Inverse Definite Minimum Time Lag)/DTL ele-ments provide overcurrent protection, each with indepen-dent settings for pickup current, time-multiplier (51) andtime delays. The user can select IEC or ANSI time currentcharacteristics. The IDMT stage has a user programmablereset characteristic, either DTL or shaped current/time resetcharacteristic to improve grading with electromechanicalprotection.
50G/51G/50N/51N Earth fault/sensitive earth fault
Earth-fault current is derived from the residual connection ofthe 3 integrated line CTs. 50 INST/DTL and 51 IDMTL/DTLelements provide overcurrent protection, each with indepen-dent settings for pickup current, time-multiplier (51) andtime delays. The user can select IEC or ANSI time currentcharacteristics. The IDMT stage has a user programmablereset characteristic, either DTL or shaped current/time resetcharacteristic to improve grading with electromechanicalprotection.
50BF Circuit-breaker fail
The circuit-breaker fail function is triggered from an internaltrip signal. Line currents are monitored following a trip signaland an output is issued if any current is still detected after aspecified time interval. This can be used to re-trip the CB orto back-trip an upstream CB. A second back-trip time delay isavailable to enable another stage to be utilized if required.
64H Restricted earth-fault scheme
The measured earth-fault input may be used in a 64H highimpedance restricted earth-fault scheme. Required externalseries stabilizing resistor and non-linear shunt resistor can besupplied.
74TC Trip-circuit supervision
The trip-circuit(s) can be monitored via binary inputs. Trip-circuit failure raises an HMI alarm and output(s).
81HBL2 Inrush restrain/second harmonic block
Where second harmonic current is detected (i.e. duringtransformer energization) user selectable elements can beblocked.
Cold load pickup
If a circuit-breaker is closed onto a “cold” load, i.e. one thathas not been powered for a prolonged period, this canimpose a higher than normal load-current demand on thesystem which could exceed normal settings. Theseconditions can exist for an extended period and must not beinterpreted as a fault. To allow optimum setting levels to beapplied for normal operation, the cold load pickup featurewill apply alternative settings for a limited period. The fea-ture resets when either the circuit-breaker has been closedfor a settable period, or if the current has been reducedbeneath a set level for a user set period.
27/59 Under/overvoltage
Each element has settings for pickup level, drop-off level andDefinite Time Lag (DTL) delays. It operates if voltage exceedssetting for duration of delay. It can be applied in load shed-ding schemes.
47 Negative phase-sequence overvoltage
Each element has settings for pickup level and Definite TimeLag (DTL) delays. It operates if NPS voltage exceeds settingfor duration of delay.
59N Neutral overvoltage
Each element has settings for pickup level and Definite TimeLag (DTL) delays. It operates if neutral voltage exceedssetting for duration of delay. Neutral overvoltage can beused to detect earth faults in high impedance earthed orisolated systems.
60CTS CT supervision
The CT supervision considers the presence of negativephase-sequence current, without an equivalent level ofnegative phase-sequence voltage, for a user set time as aCT failure. The element has user operate and delay settings.

67/67N Directional control
Phase-fault, earth-fault and sensitive earth-fault elementscan be directionalized. Each element can be user set toforward, reverse, or non-directional. Directional phase-faultelements are polarized from quadrature voltage. Earth-faultelements can be user set to be polarized from residualvoltage or negative phase-sequence voltage.
81 Under/overfrequency
Each element has settings for pickup level, drop-off level andDefinite Time Lag (DTL) delays. It operates if frequency ex-ceeds setting for duration of delay. It is typically applied inload shedding schemes.
79 Auto-reclose
Each element provides independent phase-fault and earth-fault/sensitive earth-fault sequences of up to 5 trips, i.e.4 reclose attempts before lockout. Auto-reclose sequencecan be user set to be initiated from internal protectionoperation or via binary input from an external protection.Each trip in the sequence can be user set to be either instan-taneous (fast) or delayed. The user can set each reclose(dead) time and the reclaim time.

Ambient conditions
The recloser is designed for the normal operating conditionsdefined in ANSI C37.60. This comprises an ambient tempera-ture from –40 °C to +55 °C plus solar radiation.
Altitude correction factor
The dielectric strength of air insulation decreases withincreasing altitude due to low air density. The rated lightningimpulse withstand voltage values specified in the chapter“Technical Data” apply to a site altitude of 1000 m above sealevel. For an altitude above 1000 m, the insulation levelmust be corrected according to the opposite drawing.
The characteristic shown applies to the rated short-durationpower-frequency withstand voltage and the rated lightningimpulse withstand voltage.
To select the devices, the following applies:
U W U0 x Ka
U Rated withstand voltage under standard reference atmosphere
U0 Rated withstand voltage requested for the place of installation
Ka Altitude correction factor according to the opposite diagram
Example
For a requested rated lightning impulse withstand voltageof 75 kV at an altitude of 2500 m, an insulation level of90 kV under standard reference atmosphere is required asa minimum:
90 kV W 75 kV x 1.2
Number of operating cycles
The recloser is designed for 10,000 operating cycles atnormal current.
According to the standard IEEE C37.60, the recloser has beentested for 116 short-circuit breaking operations. The actualnumber of short-circuit breaking operations is higher thanthat, and can be even more than 200 depending on the pa-rameters of the short-circuit current (amplitude, DC compo-nent).

Order number structure
The vacuum reclosers consist of a primary part as well as of acontroller or secondary part. The relevant data make up the16-digit order number. The primary part covers the mainelectrical data of the circuit-breaker poles. The controller andsecondary part covers all auxiliary devices and the controller,which are necessary for operating and controlling therecloser.
Order codes
Individual equipment versions, marked with 9 or Z in the 8th
to 16th position, are explained more in detail by a 3-digitorder code. Several order codes can be added to the ordernumber in succession and in any sequence.
Mounting parts and special versions (�)
In case of special versions, “- Z” is added to the order numberand a descriptive order code follows. If several specialversions are required, the suffix “- Z” is only listed once.If a requested special version is not in the catalog and cantherefore not be ordered via order code, it has to beidentified with Y 9 9 after consultation. The agreementhereto is made between your responsible sales partner andthe order processing department in our Switchgear Factoryin Berlin.
Configuration example
In order to simplify the selection of the correct order numberfor the requested recloser type, you will find a configurationexample on each page of the chapter “Equipment Selection”.For the selection of the auxiliary voltages, the fixing options,the controller, etc. always the last example of the primarypart was taken over and continued, so that at the end of theequipment selection (page 24) a completely configuredrecloser results as an example.
