These modules, based on the latest switching and electronic control technology, can be used as core components for medium voltage switchgear. There are two basic module types: switching modules (ISM/TEL) used to close and open primary circuits;control modules (CM/TEL) used to provide control (close and trip operations) of ISM/TEL and to replicate the auxiliary interface of conventional circuit breakers.
Switching modules are three pole units. Each pole incorporates a vacuum interrupter and single-coil magnetic actuator encapsulated in solid insulation.Control modules are P electronics units, containing built-in close and trip capacitors. These capacitors are discharged to the actuator coil in different directions to provide the relevant operations.When applied to any switchgear, a pair of modules (one switching module and one control module) must be used. The ability to choose switching and control modules separately allows any type of switchgear to be easily equipped regardless of its primary and auxiliary circuits.
Since their first introduction in the early 1990's, the modules have gained an excellent reputation among switchgear manufacturing companies. Tavrida Electric has now supplied more than 100 000 pairs of modules used in over 50 different types of switchgear (both retrofitted and brand new). These modules have been the product of many years of R&D effort by Tavrida Electric scientists and engineers and their use in your switchgear will allow you and your customers to benefit from their unique combination of features: no maintenance needed during its entire lifetime;long mechanical and interrupting life;fast autoreclosing capability; easy adaptation to any primary interface (sta-tionary or withdrawable); easy adaptation to a wide range of auxiliary voltages;easy adaptation to any signaling interface; easy SCADA compatibility; low power consumption; compact dimensions and light weight.
Some examples of application of the modules for different switchgear are presented below.

shaft interlocking interface
In contrast to the majority of conventional circuit breakers, this patented design incorporates three independent magnetic actuators: one per pole. This minimizes the number of moving parts, all of which are symmetrical about the central axis.
The vacuum interrupter and the magnetic actua-tor are located at opposite ends of a hollow sup-port insulator. The actuator armature is rigidly coupled to the vacuum interrupter moving con-tact by a linear drive insulator within the support insulator. This provides direct linear movement in both directions and avoids the use of rotating shafts, bearings and bell cranks. The result is a maintenance free ISM/TEL with a long trouble-free mechanical life.
The actuators are situated inside the frame as shown in the figure below. A synchronising shaft connects the three poles and performs three functions:opening synchronization of the poles;operation of auxiliary switches;link drive for mechanical interlocks on switchgear.
The design shown in the figure below is used for rated current up to 1000 A. For rated currents exceeding 1000 A, a different design (chimney type) is used. However, it is essentially similar in structure.
Instruction manual 11Switching modules ISM/TEL
Magnetic actuator
The actuator is held in its two end positions without the use of mechanical latches:in the OPEN position the armature is held by the opening spring;in the CLOSED position the armature is held by the magnetic flux produced by a ring magnet.
This actuator has only one coil. To close and trip the actuator it is necessary to inject current into the coil in different directions.
Instruction manual12 Switching modules ISM/TEL
Vacuum interrupters
Finely dispersed vacuum arc resulting from stabilizing effect ofaxial magnetic field.
The family of TELvacuum interrupters
As soon as the vacuum interrupter contacts open, the interrupting current initiates a so-called "vacuum arc" that burns essentially as plasma originating from evaporated contact material. The current continues to flow through this plasma until a zero current is reached. At this moment the arc is extinguished and a transient recovery voltage appears across the open gap. If the contact surface is locally overheated, it produces a lot of vapour, resulting in the deterioration of the vacuum followed by an electrical breakdown. To avoid this, effective control of the vacuum arc is necessary.
The most effective way to achieve this goal is to apply an axial magnetic field produced by the interrupting current itself. This method is imple-mented in vacuum interrupters developed and manufactured by Tavrida Electric for ISM/TEL modules.Several major benefits result from this design: high interrupting capacity;very compact dimensions;low chopping current (4-5 amps) This limits inductive switching overvoltages to safe values;axial magnetic field minimizes contact erosion and ensures a very long and reliable life.
Instruction manual 13Switching modules ISM/TEL
Operation
Closing
Opening
To open the interrupter a current of oppositepolarity, derived from the opening capacitor inthe control module, is passed through the coil for15-20 milliseconds. (Line 4-5)
This current partially demagnetises the ringmagnet and reduces the magnetic holding force
Opposing forces from the charged opening springand the contact pressure spring cause the arma-ture to release and accelerate rapidly. After 2 mmof free travel it engages with the drive insulatorand thus the moving contact.
The peak force produced by the armature at thispoint exceeds 2000 N which ensures easy break-ing of any micro-welds at the contact surfaceswhich can appear due to short circuit currentaction.
The moving contact accelerates rapidly ensuringa high interrupting capacity. (Line 5)
At full travel (Line 6) the armature, drive insula-tor, moving contact assembly is again held openby the opening spring force.
The synchronising shaft is also driven through44 of rotation during the opening operation andprovides position indication, auxiliary switchoperation and mechanical interlocking actions.
Typical oscillograms of ISM/TEL module operation
In the OPEN position the vacuum interrupter con-tacts are held open by the force of the opening spring in the actuator acting through the drive insulator. To close the vacuum interrupter contacts a current pulse, derived from the closing capacitor in the control module, is injected into the actuator coil. The current in the coil produces a magnetic flux in the gap between the upper yoke and the actuator armature.Rising coil current increases the magnetic flux and the electromagnetic attraction between yoke and armature increases to overcome the restraining force of the opening spring. (Line 1)
The armature, drive insulator and moving contact start to move.
As the armature moves towards the upper yoke the magnetic air gap decreases and consequently the magnetic attraction force increases. This increasing force accelerates the armature, drive insulator and moving contact to a closing speed of 1 m/s. This optimum speed ensures a complete absence of contact bounce and reduces the probability of pre-strikes of the vacuum gap before the contacts close. (Line 2) The accelerating armature also generates a back emf in the coil and reduces the coil current (Line 1-2) At contact close (Line 2), the moving contact stops but the armature travel continues for 2mm under rapid deceleration caused by compressing the contact pressure spring.
At the limit of its travel the armature latches mag-netically to the upper yoke. (Line 2a) The moving armature induced back emf collapses and the coil current again increases (Line 2a-3) saturating the ring magnet.
This saturation increases the power of the ring permanent magnet to a level that generates flux to hold the armature in the CLOSED position after the coil current has been cut off by an auxiliary switch. ( Line 3) Testing has proved that this flux is sufficient to hold the actuator CLOSED even under vibration and impact conditions.
The travel of the armature also compresses the opening spring in preparation for the next opening operation.The synchronising shaft is also driven through 44 of rotation during the closing operation and pro-vides position indication, auxiliary switch operation and mechanical interlocking actions.
Instruction manual14 Switching modules ISM/TEL
Manual closing
Closing can only be carried out through the con-trol module.If the normal substation supply to the control mod-ule is deenergized it may be operated using a portable low voltage source through special emer-gency power supply inputs. TEE has developed a generator machine (TEE-HSSG-01) which provides a sufficient level of voltage for charging close capacitors of CM/TEL. The generator is enclosed in metal case, which is convenient for transportation and supply connection.
Manual opening
The module may be manually opened. By rotating the synchronizing shaft, a force exceeding the magnetic attraction forces of the ring magnet is applied to the armature, which then starts to move. As the air-gap increases the opening spring and contact pressure spring overcome any magnetic holding force and the interrupter opens.
Note: It is not possible to close ISM/TEL by forcing the synchronizing shaft to rotate. Any attempt to do so will result in damage to the mechanism and possible injury to personnel.
Alternatively, a stationary type power supply unit (TEE-PSU-01) can be used to provide CM/TEL close capacitors charging. The set consists of ORACLE charger and HAWKER GENESIS miniature battery.

Operation
Operation modes
Capacitor chargingBoth the "Close" and "Trip" capacitors are charged when an auxiliary voltage is applied to the "Power Supply" input.Alternatively the "Close" capacitor can be charged from the "Emergency Power Supply" input. This feature allows ISM/TEL to be closed using a low voltage alternative power supply (for example, handset battery) when the main "Power Supply" input is dead.Alternative charging of the "Trip" capacitor can be achieved by using the "Current Power Supply" inputs connected to CTs. This alternative method also requires the "Current Power Supply Mode" input terminals to be short-circuited. This feature allows the control module to maintain tripping ability in the event of a long control power supply outage.For more detailed information refer to the descrip-tion of relevant inputs.
ClosingISM/TEL can be closed through the "Close and Supervision" input or the "Dry Contact Close" input. For more detailed information refer to the description of the relevant inputs. Note: after mechanical tripping, closing will not proceed unless Trip instruction is activated via any applicable input.
TrippingISM/TEL can be tripped through the "Trip & Supervision" input, the 'Alternative Trip & Supervision Input", the "Dry Contact Trip" input and any of the "Current Power Supply" inputs if "Current Power Supply Mode" input terminals are open-circuited.For more detailed information refer to the descrip-tion of the relevant input.
Anti-pumping dutyFor any close and trip inputs the following rule is applicable.During a close operation, if a trip instruction is received before the close instruction becomes passive then the close instruction will be blocked. For the next close operation the close instruction must be re-applied after the trip instruction has become passive.
Blocking dutyFor any close and trip inputs the following rule is applicable.If a close instruction is received while a trip instruction remains active then the close instruction is blocked.For the next close operation the close instruction must be re-applied after the trip instruction hasbecome passive.
SupervisionThe control module simulates the behaviour of a conventional circuit breaker with regard to super-vision of the health of the "Close" and "Trip" cir-cuits. To achieve this, the supervision circuits of the switchgear can be connected to the "Close & Supervision" and the "Trip & Supervision" inputs. For more detailed information refer to the descrip-tion of the relevant inputs.

Origins and operation of inputs
"Close & Supervision " inputThe "Close & Supervision" input simulates the behaviour of the closing coil of a conventional circuit breaker (CB) with an NC auxiliary switch in series.
Typical wiring of the dose and supervisory circuits to conventional circuit breaker
SPR -supervisory relay, SR - signal relay, CS- closing switch contact R - current limiting resistor, AS - auxiliary switch, CC - closing coil.
The input can be in low or high impedance mode depending on the conditions described below. When the input is in low impedance mode its resistance is determined by an external resistor connected to the terminals of the "Closing Coil Simulator".
Typical wiring of the close and supervisory circuits to CM/TEL
SPR- supervisory relay, R-current limiting resistor, AS - aux-iliary switch, CC -closing coil SR- signal relay, CS- closing switch contact, ER -external resistor for simulation of closing coil resistance, 1, 2 - "Close & Supervision" input terminals, 3,4 - "Closing Coil Simulator" input terminals.
Low impedance mode of the input occurs if the following conditions are met: ISM/TEL is open (ISM/TEL auxiliary switch closed);Closing capacitor is charged;No malfunction is detected;
In this state the close circuit supervision current, limited by resistance of the supervision relay coil flows through the input. The relay is activated and signals that ISM/TEL is ready to close. If the control switch CS is closed, the total control voltage is applied to the input. The current is no longer limited by SPR coil resistance, so it increases and exceeds the minimum level accepted as a "Close" instruction. If this current is sustained for a period longer than the "Close" instruction acceptance time, then the "Close" instruction is accepted, the closing capacitor is discharged into the actuator coil and the ISM/TEL module closes. The input remains in the low impedance mode for 60 ms to pro-vide enough time for the operation of the signal relay SR. After this time has expired, the input impedance becomes high and remains in this mode until the conditions specified above are met again.
If the supervision relay coil short circuits, this must not lead to the uninstructed operation of the circuit breaker. To avoid this situation, resistor R is generally included in the circuit. This resistor limits the current values below the minimum accepted level. However this current is generally higher than the maximum sustained current. If this is the case, the input impedance becomes high after 200 ms; it then stays in the low impedance mode for 200 ms every 50 s to check the status of the supervision circuit. The supervision circuit is considered healthy when the input current drops below the maximum sustained level. In this situation the input impedance mode becomes low again.

"Closing Coil SimulatorThis input is used for the connection of external resistor ER, which replicates the resistance of the closing coil of a conventional circuit breaker. This resistor determines the resistance of the "Close & Supervision" input in the open state.
"Trip & Supervision" inputThe "Trip & Supervision" input simulates the behaviour of the trip circuit of a conventional circuit breaker with NO auxiliary switch in series.
Typical wiring of the "Trip & Supervision" and "Trip Coil Supervision" circuits to conventional circuit breaker
The input can be in low or high impedance mode depending on the conditions described below. When input is in low impedance mode its resist-ance is determined by external resistor connected to the terminals of the "Tripping Coil Simulator".
Typical wiring of the "Trip & Supervision" and "Trip Coil Supervision" circuits to CM/TEL
Low impedance mode of the input occurs if the following conditions are met: ISM/TEL is closed (ISM/TEL auxiliary switch is open);Tripping capacitor is charged;No malfunction is detected;
In this state the trip circuit supervision current, limited by resistance of the supervision relay coil, flows through the input. The relay is activated and signals that ISM/TEL is ready to trip. If control switch TS is closed then the total control voltage is applied to the input. The current is no longer limited by relay coil resistance, so it increases and exceeds the minimum level accepted as a "Trip" instruction. If this current is sustained for a period longer than the "Trip" instruction acceptance time, then the "Trip" instruction is accepted, the tripping capacitor is discharged into the actuator coil and the ISM/TEL module opens. The input remains in the low impedance mode for 60 ms to provide enough time for operation of the signal relay SRI. After this time has expired, the input impedance becomes high and remains in this mode until the conditions specified above are met again.
Instruction manual38 Control modules CM/TEL
If the supervision relay coil short circuits this must not lead to the uninstructed operation of the circuit breaker. To avoid this situation, resistor R1 is generally put in series with the relay coil. This resistor limits the current values below the minimum accepted level. However this current is generally higher than maximum sustained cur-rent. If this is the case, the input impedance becomes high after 200 ms; it then stays in the low impedance mode for 200 ms every 50 s to check the status of the supervision circuit. The supervision circuit is considered healthy when the sustained current drops below the maximum sustained level. In this situation the input impedance mode becomes low again.
Trip Coil Supervision" inputThe "Trip Coil Supervision" input is used to simu-late the tripping coil of a conventional circuit breaker (see previous page). It allows the "Trip Coil Supervision" relay to be connected, which can supervise the health of the trip coil irrespective of the position of ISM/TEL. The input can be in the low or high impedance mode depending on the conditions described below. When the input is in the low impedance mode, it's resistance is determined by the external resistor ER1 con-nected to the terminals of the "Tripping Coil Simulator".The input is in the low impedance mode if no malfunction is detected.In this state the trip coil supervision current, lim-ited by the resistance of the supervision relay coil, flows through the input. Relay SPR2 is activated and signals that the trip coil is healthy.
"Tripping Coil Simulator"This input is used for the connection of external resistor ER1, which replicates the resistance of the Tripping Coil of a conventional circuit breaker. This resistor determines the resistance of the "Trip & Supervision" and "Trip Coil Supervision" inputs in the open state.
'Alternative Trip & Supervision" inputThe 'Alternative Trip & Supervision" input simu-lates the behaviour of the alternative shunt release of a conventional circuit breaker with NO auxiliary switch in series.
Typical wiring of the 'Alternative Trip & Supervision" circuit to conventional circuit breaker
SPR3 - supervisory relay, R3 - current limiting resistor, 5R3-signal relay, ATS - alternative tripping switch contact, AS-auxiliary switch, SRC - shunt release coil
The input can be in the low or high impedance mode depending on the conditions specified below. When the input is in the low impedance mode, its resistance is determined by an external resistor connected to the terminals of the 'Alternative Tripping Coil Simulator".
Instruction manual 39Control modules CM/TEL
Typical wiring of the 'Alternative Trip & Supervision" circuit to CM/TEL
SPR3S-supervisory relay, R3- current limiting resistor, SR3-signal relay, ATS - alternative tripping switch contact ER2-external resistor for simulation of the SRC resistance, 10,11 -terminals of the "Trip & Supervision" input 12,13- "Tripping Coil Simulator" input terminals.
Functionality of the input is identical to that of the "Trip & Supervision" input.
Alternative Tripping Coil Simulator"This input is used for the connection of external resistor ER2, which replicates the resistance of the alternative shunt release of a conventional circuit breaker. This resistor determines the resistance of the 'Alternative trip and Supervision" input in the low impedance mode.
"Dry Contact Close" inputThe "Dry Contact "Close" input can be used to close ISM/TEL. The close instruction is accepted through this input if the following conditions are met:ISM/TEL is open (ISM/TEL auxiliary switch is closed);Closing capacitor is charged;No malfunction is detected;"Dry Contact "Close" input is short circuited longer than "Close" instruction acceptance time;"Dry Contact "Trip" input is open circuited.
"Dry Contact Trip" inputThe "Dry Contact "Trip" input can be used to trip ISM/TEL. The "Trip" instruction is accepted through this input if the following conditions are met:Tripping capacitor is charged;No malfunction is detected;"Dry Contact "Trip" input is short circuited longer than "Trip" instruction acceptance time.
"Current Power Supply"The "Current Power Supply" inputs can be con-nected to CTs and may be selected for either but not both of the following functions: to charge the trip capacitor,;to simulate the operation of the series trip coils of a conventional direct tripping circuit breaker. To select Trip Capacitor Charging the "Current Power Supply Mode" terminals must be short circuit together by a local jumper. The trip capacitor is charged by line current CT power but trip operation is only available from "Trip" instructions through other appropriate inputs.To select Series Trip Coil simulation the "Current Power Supply Mode" terminals must be open cir-cuited.The trip capacitor is again charged by line current CT power but trip operation results from a trip instruction from the direct tripping relay.
"Current Power Supply Mode" input
This input is used for selection of the operating mode of the "Current Power Supply" inputs as described above.
ISM/TEL auxiliary switch inputThis input is used for connection of the NC auxil-iary switch of ISM/TEL.
Instruction manual40 Control modules CM/TEL
Destination and operation of outputs
"Failure" outputThe "Failure" output is used to signal the detec-tion of any malfunction as specified in the section "Malfunction". The output is represented by CO relay contacts. Its NC contacts open when no malfunction is detected.
"Emergency Trip" outputsThe "Emergency Trip" output simulates the behaviour of the relevant mechanical switch of a conventional circuit breaker.The output is represented by two bistable relays (with NO and CO contacts). These relays change their position at closing. At tripping, they switch to the original position if the trip instruction has been accepted through the "Trip and Supervision" input.If the trip instruction has been accepted through another input, the relays do not switch to the original position. The relays can be reset by the application of the control voltage to the "Emergency Trip Reset Input" when the switching module under control is in the Open position.
"Fleeting" outputThe "Fleeting" output is used to simulate the action of the relevant mechanical switch of a conventional circuit breaker during a Trip opera-tion. This output is represented by a relay, which closes NO contacts in 255 ms after the tripping of the ISM/TEL (closing of the ISM/TEL auxiliary switch) and opens these contacts after an addi-tional 505 ms.
"Passing" outputThe "Passing" output is used to simulate the action of the relevant mechanical switch of a conventional circuit breaker during a Close operation. This output is represented by a relay which closes NO contacts in 255 ms after closing of the ISM/TEL (opening of the ISM/TEL auxiliary switch) and opens these contacts after an addi-tional 505 ms.
"Actuator Coil" outputThis output is used for connection of the coil of the magnetic actuator.
"Ready" outputThe "Ready" output is used to indicate that the control module is ready to accept "Trip" and "Close" instructions through any of the relevant inputs. This state appears if the following condi-tions are met:"Trip" and "Close" capacitors are fully charged;No malfunction is detected. This output is represented by an NO relay that holds the contact closed if the conditions speci-fied above are met.

When ISM/TEL-12-20-1000 is used in a stationary switchgear application with Isc value reaching 20kA, an additional supporting bar must be used to interconnect all 3 poles.
When ISM/TEL-12-31,5-1600 is used in a stationary switchgear application with Isc value of more than 25kA, the use of all fixing points is compulsory.
Mounting of the ISM/TELIn any switchgear application, the ISM/TEL mod-ules shall be installed with the actuator/inter-rupter drive axis vertical. (For ISM types, the actuator may be either below or above the inter-rupter.)Primary connections to the ISM/TEL modules shall be made using rigid busbars, the design of which shall avoid excessive static force being applied to the modules. Additionally, in draw out switchgear, support insulators shall be used to avoid transferring excessive contact forces to the ISM/TEL module when operating the isolating mechanism.
With stationary switchgear, contact isolation forces do not appear and additional support insu-lators are generally not needed.

Mounting of the CM/TEL
It is highly recommended to install CM/TEL inside the low-voltage compartment. In case of CM/TEL installation at the front panel, it is obligatory to install it inside metal enclosure. No openings or holes to the high-voltage compartment is allowed. CM/TEL is not sensitive to the operation position. However, general practice is to mount it in a such way to provide access to the front panel with status indication. CM/TEL shall be segregated from high-voltage compartment by a mild steel shield at least 1 mm thick. All secondary wiring coming out from low-voltage compartment including the interconnection between CM/TEL and ISM/TEL shall be done with the help of shielded cable.The length of secondary wiring inside the high-voltage compartment shall be minimized.
No loops are allowed while secondary wiring installation.The length of CM/TEL and ISM/TEL connecting cable shall not exceed 5m.For the detailed description regarding the installation of the CM/TEL, please refer to the Attachment 5.When the CM/TEL is installed inside a closed compartment (especially with internal heating elements), special care shall be taken with regard to maximum air temperature inside the compartment. Under no circumstances the limits specified in the technical specification for CM/TEL shall be exceeded.
The following diagrams demonstrate examples of the installation of CM/TEL and ISM/TEL in draw-out and stationary switchgear.
Earthing ISM/TEL
ISM/TEL shall be earthed through the earthing stud as shown in the figure below.
In case of ISM/TEL application in solid-earthed neutral systems, the earthing shall be provided with the help of isolated wire or a copper bar with the cross-section not
2less than 4mm . In case of ISM/TEL application in isolated neutral systems, the the choice of the earthing conductor cross-section shall be made with regard of the IEC 6021-2 or the cross-section table below:

Interlocking
Interlocking interface of ISM/TEL
A
A
BB
C
C
Two basic types of interlocks are generally applicable: A mechanical interlock that:1. In non-withdrawable switchgear prevents operation of the primary isolators when ISM/TEL is
closed.2. In withdrawable switchgear prevents access to and operation of the truck isolating mechanism when
ISM/TEL is closed.
An electrical interlock that:1. In non-withdrawable switchgear prevents closing of ISM/TEL when the isolator is in an intermediate
position.2. In withdrawable switchgear prevents closure of ISM/TEL unless the truck is either fully engaged
or withdrawn.
The mechanical interlock is connected to at least one of the interlocking pins or directly to the synchronizing shaft.
If both stub shafts of the synchronizing shaft are used, the sum of the attached moments of inertia
-4 2shall not exceed 4.3 x 10 kg/m .It is not permissable to perform electrical trip/close commands while blocking the interlocking pins or the synchronization shaft mechanically.
Instruction manual56 Application guide
Note: Equivalent moment of inertia applied to all functions used for interlocking, manual tripping and position -4 2
indication shall not exceed 4.3 x 10 kg/m . (The distance between the axis of the interlocking pin and the axis of the synchronizing shaft is 35 mm. Equivalent moment of inertia of the mass M attached to the interlocking pin
2is calculated as 0.035 M.)
AC - actuator coilAS - auxiliary switchPS - position switchTypical electrical interlocking diagram
If the attached part is joined to a lever mechanism, the weight (including directly moved parts) shall be decreased in proportion of the lever.
If the interlocking mechanism is directly attached to the synchronization shaft the moment of inertia of the attached mechanism shall not
-4 2exceed 4.3 x 10 kg/m .

Interlocking interface of ISM/TEL
The following conditions must be fulfilled in carrying out mechanical interlocking:If the interlocking mechanism is attached to one of the interlocking pins, the weight of the directly attached movable part to the interlocking pins shall not exceed 0,35 kg. If both interlocking pins are used, the sum of the attached masses shall not exceed 0,35 kg.
Electrical Interlock
An electrical interlock must be provided by the connection of the NC contact of the position switch of the relevant device (disconnector or draw out truck) in series with the ISM/TEL auxil-iary switch as shown in the figure below.
The position switch must be positively driven in both directions and must fully operated before the interlocked device starts to move to its alternative position.
Connection of the position indicatorA circuit breaker position indicator may be attached to one of the pins or to the interlocking levers.
Connection of manual trip facilityA manual trip facility (button, pedal, lever, etc.) may apply external force to one of the pins when ISM/TEL is required to trip manually.When not in use, it must not apply any static force to the synchronizing shaft or pins. The tripping force required can be as high as 250 N, therefore it may be necessary, rather than directly pushing the pin, to magnify the force with a lever system.

Wiring
Typical wiring of CM/TEL-X/X-12-01A
Dry contact inputs are available at all CMs for close and trip operations. Each of these inputs can be connected with one or more parallel-switched dry contacts. In no case must an external voltage be applied to these in puts.ISM/TEL and CM/TEL modules shall be interconnected by four wires as shown in the previous figure.If, despite effective electrical closing lock-out, a Close attempt is made, the Malfunction LED
will blink 2 times (see malfunction indication table). The reason for the malfunction must be removed to eliminate the electrical closing lock-out and to activate the Close readiness. The wiring of other terminals of ISM/TEL and CM/TEL is determined by the requirements of the particular switchgear. Several typical examples of wiring of different CM/TEL versions are presented on the following pages.

Adjustment of the control inputs
This procedure is applicable for CM/TEL-X/X-12-02A, CM/TEL-X/X-12-03A.Close & Supervision", "Trip & Supervision", "Alternative Trip & Supervision" inputs shall be adjusted to the required control voltage and current. This adjustment is achieved by the connection of a proper external resistor to the relevant inputs (see also section "Control Modules Operation") and by selection of the control current with the aid of relevant selection switches (see also Section "Control Modules Design").
For rated voltages not exceeding 60 V the critical parameter of the external resistor (in addition to its value R) is rated power P. For rated voltages exceeding 60 V, the critical parameter is impulse power Pi, that can be absorbed by the resistor from a 100 ms current pulse. These values are determined by rated voltage and current of the input and shall be chosen in accordance with the following table. (See also Notes below the table.)
Note 1: The power ratings shown above ensure reliable operation of the external resistor in a static condition. Some resistors are highlysensitive to temporary overloads caused by frequent switching operations or application of high energy lightning impulses. In these cases, the required rated power may exceed that shown in the table above. In case of doubt please contact manufacture.Note 2: When choosing the value of R, check that it is less than the combined value of the resistors R,R1andR3 connected in series with the supervision relays by at least 3.5 times (See also Section "Destination and operation of inputs"). If this is not achieved then failure of a supervision relay coil to a short circuit condition could result in an uninstructed circuit breaker operation.Note 3: External resistors applied shall be wire type and shall have tolerance 5% or better.

General
Commissioning and servicing is only permissible by qualified and trained personnel. In so far as an installation where commissioning and change work is carried out on live equipment, relevant safety regulations must be adhered to (in accordance with appropriate national standards).This procedure applies to both primary and secondary power circuits.When mounting and installation a newly designed panel for the first time, an acceptance of the equipment must be carried out with TAVRIDA ELECTRIC in order to ensure the proper installation conditions.The ISM must always be tested and operated with the CM. Individual testing is not possible and leads to the destruction of the ISM.The selection switch of the relevant input shall be set to a required control current as shown below.
Commissioning tests
After the installation of the ISM/TEL and CM/TEL modules, please follow the routine test procedure specified for relevant switchgear. This procedure shall cover (but shall not be necessarily limited to) the following tests:
Operation test
1. Apply auxiliary power. Check CM/TEL signaling: LED indicator "Power" shall light immediately after power application;LED indicator "Ready" shall light within 15s after power application;Dry contact "Ready" shall switch on within 15s after power application; LED indicator "Failure" shall not light.
2. Prove close and trip operations using all applicable inputs of CM/TELIn the factory, the magnetic actuator coils are connected and tested according to the existing circuit diagram. If the actuator coil is connected with reversed polarity it is possible that the first operations cannot be performed successfully. This is not a failure of the ISM and after a few switching operations this possible effect disappears permanently (unless the polarity is changed again).Check proper signaling. Do not apply a "Close" instruction when CM/TEL is not ready for the next operation ("Ready" LED indicator is off). The operation will be blocked.
3. Check antipumping duty.Apply a "Close" instruction followed by the application of a "Trip" instruction. ISM/TEL shall perform CO duty.This checking is normally done using local control pushbuttons.
4. Check blocking duty.Apply a "Trip" instruction followed by the application of a "Close" instruction. ISM/TEL shall stay open. This checking is normally done using local control push buttons.
5. Check proper operation of mechanical and electri-cal interlocks.
Instruction manual62 Application guide
High voltage test
Apply a slowly rising AC voltage to each of the vacuum interrupters and support insulation. The voltage shall be increased up to the limit specified in the Technical Specification and then kept steady for 1 min.During testing of vacuum interrupters, self-fading restrikes may appear.In this case, reduce the voltage slightly until the restrikes disappear (for 10-15 seconds) and then increase again until the required test level is achieved.Test vacuum interrupters separately to avoid their mutual influence caused by the above mentioned restrictions.If test set uses long connecting wires, the restrikes may cause switching surges resulting in insulation failure during the test. To avoid this, try to use the shortest wires possible. To coordinate the surge impedance between the test set and switching module, an extra resistor as shown below shall be used.
Insulation resistance test
Use standard methods to check the insulation resistance of the auxiliary insulation. It shall not be below the limits given in the switching mod-ule's technical specification.
Main contact resistance test
Use standard methods to check resistance of the main contacts of ISM/TEL. Values must not exceed limits specified in the switching module's technical specification.
Instruction manual 63Application guide
Maintenance
These modules are inherently maintenance free. However when maintenance is carried out on the switchgear in which they are assembled, commissioning tests should be repeated. Test results should be treated as below:
Operation test
Modules shall be operable. Otherwise, check the control circuitry.If necessary, change the failed module.High voltage testUse a dry cloth or a cloth soaked in alcohol to clean the insulation prior to testing. Dielectric strength of interrupters and support insulation may deteriorate in service. A reduction to 80% of initial value is acceptable, below this the module should be replaced.
Insulation resistance test
Where necessary, clean the insulation before test-ing.The insulation resistance shall comply with the Specification.In the case of noncompliance try to find the "weak point". Note that, generally, there are other devices installed parallel to the modules
Contact resistance test
If the Module has contact resistance that exceeds the specified limit but is less than twice this limit, continuation of use is possible, if actual continuous current does not exceed the following:
where:Ia, Ra - actual current and contact resistance respectively,Ir, Rr- rated values.
If the contact resistance more than doubles the specified limit, the Module must be replaced.
