The closing time is the time period from the energising of the closing circuit to the time when all three poles make
contact.

Pre-arcing time

Interval of time between the initiation of current ow in the rst pole during a closing operation and the instant
when the contacts touch in all poles for three-phase conditions or the instant when the contacts touch in the
arcing pole for single-phase conditions.

poles are separated.

NC Normally closed contact
NO Normally open contact
PCD Pole center distance
SCADA Supervisory control and data aquisition
VCB Vacuum circuit breaker

General

Figure 1

In comparison to conventional circuit breakers, the Tavrida Electric vacuum circuit
breakers comprise of two components:

· The ISM (Figure 1)

· The CM for controlling the ISM and monitoring both modules (Figure 2)

Both modules must only be operated together and are meant for indoor
installations only. The possibility to choose ISM and CM separately allows any type
of switchgear to be easily equipped with regard to its primary and auxiliary circuits.

Figure 2

Compact design

Tavrida Electric develops and produces all vital parts of the circuit breakers themselves. The result of intensive
inhouse fundamental and material research are extremely compact vacuum interrupter and magnetic actuators.
Optimal selection of all components makes these the most compact and light weight vacuum circuit breaker in
the world.

Long life

Contact erosion is minimised by use of axial magnetic eld. All the switching elements are assembled axially and
symmetrically in one straight line. This means that all the mechanical movements are exclusively direct and linear.
30 000 operating cycles can be achieved with rated current without replacing or adjusting any components.

1

Maintenance free

The ISM is maintenance-free over the expected life of at least 25 years.

Highest availability

In addition to minimising the number of failure-critical components, the Tavrida Electric circuit breaker monitors
its status continuously. In the unlikely event that a fault occurs it is indicated and can be rectied before an unsuc­cessful switching attempt is made. This leads to higher availability of the electric power supply system.

Des ign and Method of Operation: ISM and CM

The ISM vacuum circuit breaker uses three single-coil magnetic actuators, one per pole. The three actuators are
mounted in a steel frame and mechanically linked by a synchronizing shaft (Figure 3).

Closing
In the open position the contacts are kept open by the force of the opening springs. To close the contacts
the coils of the magnetic actuators are excited by a current impulse of the close capacitors of the CM. As a
result the contacts close. At the same time the opening springs are compressed. In the closed position the
contacts are kept closed by means of the magnetic force only. The ISM maintains the closed position
without mechanical latching also in case of a failure of the auxiliary power supply (Figure 5).

Opening

To open the contacts a current impulse in the reverse polarity derived from the opening capacitors of the
CM is injected in the coils of the magnetic actuators releasing the magnetic holding force. The compressed
opening springs and contact pressure springs open the contacts (Figure 5).

Manual-Emergency-Tripping

The ISM can be tripped mechanically without auxiliary power supply (emergency trip). It may be opened
manually by means of interlocking shaft rotating counter-clockwise. The interlocking cam of interlocking
shaft act on the armature, when then starts to move (refer to chapter “Installation/Primary part/
Interlocking”, page 24). As the air gap increases, the opening springs and contact pressure springs
overcome any magnetic holding force and the module opens.

Manual Closing

The ISM can only be closed electrically via the CM. In the case of a failure of auxiliary power supply the
contacts can be closed using an alternative auxiliary power supply such as a battery. Mechanical closing is
not possible and leads to the destruction of the ISM.

Coordination of Minimum Clearances

In case the minimum clearance L3 due to 25/31 kA short circuit current exceeds the minimum clearance L2 due to the
rated insulation level, the higher clearance between ISM-frame and adjacent busbars is to be selected.

Heating

The ISM are designed in such a manner that at the rated current specied on the rating plate of the ISM and at 40°C
ambient temperature, with free surroundings, no impermissible high temperatures will arise at the hottest spots of
the ISM. In order to decide whether for an ISM in the respective panel more intensive heat dissipation or a reduction
of the rated current values are required, a temperature rise test according to the relevant standards is recommended.

Protective Grounding

For personnel protection the metal housing of the ISM must be
connected according to the applicable regulations, such as DIN
VDE 0141, DIN VDE 0151, IEC 6021-2 via the marked two ground
screws of the ISM to the ground arrangement of the particular
panel. One or both grounding bolts can be used. If two ground
connections are used, at each grounding bolt the half total cross
section shall be connected. The ground connections can be carried
out with cables or at copper bars. The cross section must be
dimensioned such that a worst-case fault current (short circuit)
does not cause a weakening of the ground connections (Figure 27).

Reference values for total cross sections of ground connections (copper):

Interlocking

Interlocking mechanism

Interlocking mechanism of the module is based on operation of an interlocking shaft that can be rotated clockwise or
counter-clockwise. When the interlocking shaft is rotated clockwise the module becomes acceptable for “close” and
“open” operations. Hereinafter this position of the module is called “unlatched”. When the shaft is rotated in reverse
direction, i.e. counter-clockwise, the module becomes “open and locked”.

If the module is closed, rotation of the interlocking shaft from “unlatched” to “open and locked” position leads to the
manual tripping of the module and afterwards to the mechanical blocking of the actuator.

Working principle of the mechanical interlocking mechanism (Figures 28, 29, 30, 31, 32).

Figure 32

Initial state: ISM is open and locked.
Turn interlocking shaft clockwise to unlatched position.

Mechanical Interlocking

Mechanical interlocking depends on interlocking shaft rotation (refer to gures 28 to 32). The mechanical interface
for the connection of mechanical interlocking is placed at the ISM frame between the terminal blocks XT1, XT2
(refer to gure 35). There is a slot on the visible face of the interlocking shaft. If the slot is directed vertically the
module is in “unlatched” position. If the slot is directed horizontally the module is in “open and locked” position.

A handle connected directly to interlocking shaft via mating part is recommended. This handle shall be freely rotated
up to 90 degrees in both directions. The handle operated by ngers shall be dimensioned so as to provide rotating
force in accordance with local standards.

Figure 35

Interlocking shaft with mounted interlocking lever.

Possible tasks of the mechanical interlocking:

· Prevents operation of the disconnectors when switching module is closed (stationary type of switchboard)

· Prevents operation of the truck isolating mechanism when switching module is closed (draw out type)

Design of mechanical interlocking (by example of a draw out unit, gures 33, 34).

Load capacity of interlocking shaft

Interdependence between torque on the interlocking shaft and turning angle of the shaft when switching modu­le has been previously switched o is presented on gure 36. Peak values of the torque are from 0.56 to 0.84 Nm.
When shaft is rotated counter-clockwise the interlocking unit is moved from “Unlatched” position to “Open and
locked” one, and otherwise. Operation zone of microswitch S14 when it becomes closed or open in “Unlatched” or
“Open and Locked” positions respectively is hatched.

If switching module is closed before rotation of the interlocking shaft and manual trip operation is fullled the peak
value of the torque can be up to 2Nm.

Figure 36

Torque on the interlocking shaft

Electrical Interlocking

Electrical interlocking is also coupled with the interlocking shaft rotation (refer to chapter “Switching and control
functions/Internal electrical interlock”, page 38). If the mechanical interlocking is eective, then the electrical
interlocking contact is activated synchronously. Electrical interlocking occurs during rst 10 degree of interlocking
shaft rotation whereby actuator coils are disconnected from the control module.

Main Contacts Position Indicator

The position indicator works as follows. There are two runners on the synchronizing shaft, any can be chosen to
activate movable part of indicator, attached to wire. The movable part has a sticker with two printed symbols, one for
Open position of the switching module, the other for Closed one. Connection of control wire to runner is described in
“How position indicator can be attached and mounted” in detail.

When switching module comes to Open position the runner pulls the wire and corresponding symbol in inspection
window becomes visible (see gure 44). When switching module comes to Close position the spring in the indica­tor provides reverse movement of the wire and symbol is changed to that one shown on gure 45.

CM_16 Series Factory Programmable Options

The CM_16 series is a exible control module option with an array of factory programmable settings for optimizing control
of the ISM breakers. When ordering a CM_16, the model code along with the pre-programmed settings code should be
submitted to Tavrida. Use the table on page 33 for conguration of a settings code based on the following options guide:

Breaker Type

To optimize the closing and trip pulses to the ISM actuators, this option sets various features of the CM_16 output power

3

algorithm. Each model type of the ISM_Shell series breakers can be selected. Note that connection to an ISM other than the
one selected will produce a malfunction signal.

Undervoltage Functions

The CM_16 series has an option for automatic trip of the ISM on loss of auxiliary supply. The CM_16 will issue a trip command
when the auxiliary supply drops below its minimum threshold (6VDC for the CM_16_1(60) and 60VAC / VDC for the
CM_16_1(220) or CM_16_2(220)).

When set to “ON“, the undervoltage delay parameter becomes active. This can be set from 0 to 60 seconds delay before the CM
issues a trip command after loss of auxiliary power.

Similary, the undervoltage reclosing function becomes active. If set to “2“, the breaker will automatically close when auxiliary
power is restored with a delay time as set by the undervoltage reclosing delay parameter.

Digital Outputs

The CM_16 series has x3 output relays for external signalling such as lamps or relay alarm inputs. Each output has ve settings
options. The output can be disabled; signal close / open position of the breaker primary contacts; signal a loss of auxiliary
supply; signal ready for operation; or signal a malfunction.

Trip / Close Delays

The ISM breaker series have high speed actuators for trip and close operations. The CM_16 by default is set for a 12ms trip
and close delay time for normal breaker operations. For arc ash mitigation, fast transfer, or other unique applications, this
delay time can be adjusted for trip and close independantly from 4ms to 40ms in 1ms increments. Note that for delay times
less than 12ms the fault interrupting rating of the ISM may need to be reduced; consult Tavrida Applications Engineering for
information.

Trip / Close Inputs

The CM_16 series use dry contact trip and close inputs, using any normally open contact by default as the trigger. For some
applications such as mining, a normally closed loop is required for the trip circuit whereby any break in the trip connection
will cause the breaker to open. For this purpose the CM_16 close and trip inputs can be set independantly for either NO or NC
triggers.

Example

For a control module programmed with breaker type ISM15_Shell_2, UV on, UV delay of zero seconds, 1 trip to lockout with 60
second reclosing delay, DO1 = Close / Open Position, DO2 = Driver Ready, DO3 = Malfunction, trip delay of 12ms, close delay
of 12ms, trip input = By opening the contact, close input = By opening the contact:

Settings code = 3-10-160-245-1212-21

Trip and / or close delays below 12ms will ship with an HS sux model code. For example the CM_16_1 with 4ms trip delay for
120VAC operation will ship with model code CM_16_1(220HS).

33

Ins tallation of the CM

The installation of the CM is carried out according to the panel design either on the draw out unit or in the low
voltage compartment of the switchboard. It must be separated from the high voltage compartment. The CM shall
be installed in an grounded mild steel box with a thickness of not less than 1 mm.

The CM can operate in any mounting position. Care must be taken for good access and visibility of the terminals,
LEDs and setting elements for operation and maintenance. Basically the ambient conditions as described in chapter
“Regulations and ambient conditions” (page 73) shall apply.

Bas ic functions for all control modules

Charging of the Capacitors

Closing and trip capacitors of the CM are charged when CM is applied to the auxiliary power supply. The charged
closing capacitors correspond with the charged springs of a conventional circuit breaker. After the failure of
auxiliary power supply any pending trip or any trip command arriving to the CM up to 30s after failure of auxiliary

4

4

power supply will be executed.

Ready-LED and Ready-Relay Output

While charging the capacitors, the Ready-LED blinks. When the capacitors are charged the Ready-LED is
continuously lit and the Ready-relay output contact is closed. With a blinking or extinguished Ready-LED, the
Ready-relay output contact is open. The Ready-relay output can be used as a permissive, such as the release
condition for a breaker control.

Malfunction-LED and Malfunction-Relay Output

If the CM detects an internal or external malfunction, the Malfunction-LED will blink according to the type of
malfunction (see the “Signalling” chapter of this manual). At the same time the Malfunction-relay output contact
will close. In this way a CM-Malfunction state can be transmitted to an alarm or SCADA system. In the case of a
malfunction the Ready-LED is extinguished and the Ready-relay output contact is opened. The Malfunction-relay
output contact is closed if the CM is powered o.

Switching the ISM On and O via the Dry Contact
Inputs of the CM

close and trip operations. Each of these inputs can be connected with one or more parallel-switched dry
contacts. Under no circumstances shall external voltage be applied to these inputs as this will destroy the
CM.

The ISM can only be closed electrically via the CM. Dry contact inputs are available on all CMs for

Electrical Clos ing Lock-Out

When the ISM manual trip hub is rotated to the locked position, an internal microswitch prevents close operation
of the breaker. As the hub is rotated counter-clockwise, the ISM is mechanically tripped (if closed) followed by the
microswitch disengaging the actuator connections. This prevents the breaker from closing until the trip hub is
rotated back to the unlocked position.

38

ISM Forced Trip by an Undervoltage Relay (Optional - CM_1501
Series)

In cases where the ISM is required to trip when the auxiliary power supply voltage drops below the minimum value
an additional undervoltage relay is required (not part of the scope of supply). The trip contact of the undervoltage
relay shall be integrated into the dry contact trip command circuit of the CM. If the CM was ready for operation
before the voltage dropped below the minimum value, tripping of the ISM is possible within 30 s after the voltage
dropped below the minimum level.

Note that for undervoltage trip functions it is recommended to use the CM_16 series where possible due to the
more exible capability it provides for reclosing and UV trip delay.

Output to Magnetic Actuator and Input for ISM Pos ition
Indication

The cables between the ISM and CMnas well as the coils of the magnetic actuator are monitored permanently (see
malfunction indication table, page 43). Internally at the auxiliary switch inputs of the CM_1501 230 V DC is applied
for the ISM auxiliary switch S13. The CM_16 series does not utilize the auxiliary switch; instead the impedence of
the actuator coils is monitored for position of the breaker as well as loss of connection.

Operations Counter

Depending on site or switchgear requirements, a method of recording circuit breaker close / open operations may
be needed. The preferred method of tracking operations is to utilize the breaker wear monitor available on most
modern didgitical relays, which will calculate the remaining lifetime based on number of operations and switching
interruptions. Alternatively, a pulse counter per the table below can be ordered from Tavrida that will indicate the
number of mechanical operations. These counters can be wired to any of the 52a auxiliary contacts on the breaker.

regulations for local and national standards must be adhered to.

When designing and mounting a panel for the rst time an acceptance of the equipment must be carried out
together with Tavrida Electric in order to ensure the installation conditions.

5

The ISM must always be tested and operated together with the CM. Individual testing is not possible and
may lead to the destruction of the ISM.

Commis s ioning Primary Part

Tests at end of installation shall include at least:

· Operating conditions of ISM shall comply with
requirements of the rating plate.

· Check for damage, remove dirt or contamination

· Unsupported busbar length according to page 21, 22

· Fixing points according to page 21

· Check bolts and torques to pages 20, 21, 23

· Minimum clearances due to rated insulation voltage
according to page 22

· Minimum clearances due to electromagnetic inuence
according to page 23

· Protective grounding according to page 23

· Free air circulation around the ISM

Testing the rated insulation level to ANSI C37.06:

· For applications from 5 to 15 kV ISM the rated power
frequency test voltage is 36 kV

· For applications below 5 kV ISM the rated power
frequency test voltage is 19 kV

Commis s ioning Secondary Part

Preparation before testing the functionality shall include at least:

· Installation of CM according to page 30.

· Availability of the CM auxiliary power supply. It is recommended to use the same auxiliary power supply
as that for protection and control devices.

· Type of voltage (AC or DC) and voltage level according to selected CM type.

· Polarity of auxiliary power supply and selection of MCB according to page 32.

· Connection between CM and ISM acccording to pages 29 - 35, 63, 64.

· Checking that all secondary connections have been fastened correctly per electrical code standards

42

Operating test

Disconnect the breaker from the high voltage source before functional testing.

· Turn on the CM auxiliary power supply and check the following operating indications:

- The POWER LED must light up immediately.

-

- The READY relay contact (X2:1,2) must close within 15 s.

- The MALFUNCTION LED must not light up.

· Check of all basic and extended functions (if any) according to the chapters “Switching and Control Functions” and
“Signalling”.

The READY LED must blink during charging of capacitors and light up continuously within 15 s

after switching on. The READY relay contact (X2:1,2) must close within 15 s.

· D
voltage for ISM auxiliary switch S13 (on CM X2:7,8 and ISM XT2:15,16) amounts to approximately 230 V DC.

· After switching o the CM, there is still a voltage at the terminals of the capacitors. Only after the

Caution

MALFUNCTION LED is extinguished the voltage has dropped to a safe value.

Danger!

In 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 rst operations cannot be performed
successfully. This is no failure of the ISM and after a few switching operations this possible eect disappears
permanently (unless the polarity is changed again).

After above listed functionality tests are performed succesfully the ISM can be tested under high voltage and with
load connected.

See wiring diagram on page 63 for details on CM_1501_01 external signalling contacts NO/NC positions. CM_16
maintains the same LED indicator patterns as the CM_1501_01.

The CM_16 series control modules have three latching output relays in an SPDT conguration. Each relay can be
factory programmed for one of three functions per the chart below. See the settings code label on the right side of
the CM_16 module for as-shipped relay conguration.

The relays will change state from unasserted to asserted based on the rmware logic as outlined in the chart below.
Note that as the relays are latching types they will retain their last state (asserted or unasserted) after power loss
and complete discharge of the module capacitor bank.

Malfunction Indication Table

The self-monitoring system inside the CM detects eventual malfunctions and report them via the MALFUNCTION
LED with various blink signals. The meaning of the blink codes and the variations per type of malfunction are
shown in the following table.

The power supply

>1.5 s

The Close or Trip­command of the
CM is carried out
but the correspon­ding ISM position
signal is missing.

The Close com­mand of the CM is
not carried out as
the ISM is electri­cally locked in OFF
position.

The Close or Trip
command of the
CM is not carried
out by the ISM as
the ISM is mecha­nically
locked in the
particular position.

Description of malfunction

variants

The operating range of the power
supply of the CM, depending on the
type of voltage, its value and switch
command, is between 65-70% and
125% (Trip commands) and 80-125%
(Close commands) of the nominal
voltage. With continuous failure of
the power supply, the blink signals
continue until the capacitors are
unloaded.

Malfunction variant 1: The Close
command of the CM is carried out
by the ISM. The normally open ISM
auxiliary switch S13 has been brid­ged already due to a malfunction be­fore the Close command was given
(despite the existing malfunction,
the ISM can be switched o again by
the CM. This deletes the malfunction
indication although the malfunction
still exists).

Malfunction variant 2: The Trip
command of the CM is carried out
by the ISM. The normally closed ISM
auxiliary switch S13 has been inter­rupted due to a malfunction (the
ISM can only be placed in the close
position after the malfunction has
been eliminated).

Malfunction variant 3: The Close
command of the CM is not carried
out by the ISM as the closing lock­out contact in ISM S13 auxiliary
switch circuit is open. The malfunc­tion indication has been purposely
taken into account.

Malfunction variant 4: The Close
command of the CM is not carried
out by the ISM as it is mechanically
locked in the OFF position.

Malfunction variant 5: The Trip
command of the CM is not carried
out by the ISM as it is mechanically
locked in the ON position.

Recommendation

for malfunction

Explanatory notes to malfunction indications and operational readiness

· If the ISM is in OFF position and malfunction indications exist, ISM can be closed only after all malfunctions have
been eliminated.

· If several malfunctions appear at the same time malfunctions regarding the magnetic actuator are indicated with
priority otherwise the last malfunction that occurred.

· Usually failures need to be xed to stop malfunction indication.
During several malfunction variants of 2- or 5- blink failures, the malfunction indication will disappear with a trip
CM command.

· In case of internal CM failures please contact your nearest Tavrida Electric partner.

Special Applications:

Fast Switching

49

Fast Transfer Switching

Sensitive loads in industrial processes are often congured with a secondary primary feed from the utility for
backup and reserve power. For sectors such as oil & gas, slow transfer times from traditional switching solutions
result in motor stoppages and lost production time while processes are brought back on-line.

The high closing and opening speeds of the ISM15_Shell_2 series allow for a packaged solution. The VCB_FTS
system is comprised of specially selected ISM15_Shell_2 breakers, control modules with a faster command
recognition speed, and optional automatic transfer relays.

6

Transfer speed can be delineated by two transition types:

1. Closed transition - the backup power line is connected by closing the breaker before the main line is interrupted
(make before break).

2. Open transition - the backup power line is connect by closing the breaker after the main line is interrupted (break
before make).

The timing of the system can therefore be broken down by the following table, using the SEL-451 relay as an
example of total timing calculation:

Product Parameters Designation Response Time

ISM15_Shell_2 opening time (including CM)
ISM15_Shell_2 interrupting time (including CM)
ISM15_Shell_2 closing time (including CM)

Topen 12 ms

Tinterrupt 20 ms

Tclose 26 ms

SEL-451 open phase detection logic trip time Tsel451 10 ms

Closed transition with SEL-451 open phase detec­tion logic trip time

Open transition with SEL-451 open phase detec­tion logic trip time

Tsel451 + Tclose 36 ms

Tsel451 + Tclose + Topen 48 ms

50

Arc Flash Mitigation

A high concern for the electrical industry are incidents of arc ash, whereby a fault is initiated that causes
damage to the equipment or serious injury to operators. These faults can be caused by many factors such as poor
maintenance, equipment failure, or operator error.

In recognition of this many relay manufacturers have produced arc detection features. These generally include the
standard relay functions plus an instantaneous trip driven by arc-detecting ber optic cables within switchgear
cubicles.

The purpose of these relays is to interrupt the arc fault through instant tripping of upstream devices. The faster the
arc is suppressed, the lower the energy output and therefore less damage to equipment plus improved operator
safety.

Tavrida ISM_Shell_2 series breakers unique high speed opening characteristics allow for a packaged solution. The
VCB_FAS system is comprised of specially selected ISM15_Shell_2 breakers, control modules with a faster command
recognition speed, and optional arc mitigation relays.

The timing of the system can be broken down by the following table, using the SEL-751 relay as an example of total
timing calculation:

Product Parameters Designation Response Time

ISM15_Shell_2 opening time (including CM)
ISM15_Shell_2 interrupting time (including CM)

Regulations and

Ambient Conditions

72

Regulations

The ISM complies with the following standards:

· DIN VDE 0670, Teil 1000 Germany

· IEC 60056 International standard

· IEC 62271-100, -200 International standard

· IEC 60 694 International standard

· GB 1984-2003 China

· GOST 687-78 Russian Federation

· ANSI C37.09 North America

· ANSI C37.09a North America

The EMC Directive 89/336/EEC.
The Low Voltage Directive 73/23/EEC.

Ambient Conditions

11

Highest value ambient temperature + 55 °C
Average temperature over 24 hours + 35 °C
Lowest ambient temperature - 40 °C
Relative humidity in 24 hours max 98%
Relative humidity over 1 month max 90%
Average water vapour pressure over 24 hours max 2.2 kPa
Average water vapour pressure over 1 month max 1.8 kPa

Installation altitude

Up to an installation altitude of 1000 m above sea level, the acceptance need not take the dielectric strength of the
air into account. Above 1000 m, the external insulation measurement of the ISM must be increased by the atmospheric
correction factor Ka according to IEC 62271-1 compared to the insulation measurement at sea level (Figure 59).

Example:

Installation altitude: 2500 m
Operating voltage: 12 kV
Rated power frequency

1,50

m=1

1,40

withstand voltage: 28 kV
Rated impulse withstand voltage 75 kV
Ka factor from diagram 1.2

1,30

At sea level the installation must resist the
following test voltage values:

Corrected rated power frequency
withstand voltage: 28 kV x 1.2 = 33.6 kV
Corrected rated impulse
withstand voltage: 75 kV x 1.2 = 90 kV

Please coordinate the necessarily actions
with Tavrida Electric AG.

Liability

Damages and demands for reimbursement of expenses incurred by the customer (in the following: compensation)
for whatever legal reasons, especially due to non-compliance of obligations of the contractual obligations and for
unauthorized actions, are excluded. This does not apply, insofar as there is a compulsory liability such as according
to the product liability law in cases of malice, gross negligence, because of damage to life, the body or health,
because of damage to important contractual obligations.

Compensation for damage to important contractual obligations, however, is limited to the damage which can be
predicted as typical of the contract insofar as there is no malice or gross negligence, because of damage to life, the
body or health. A change of the obligation to provide proof to the disadvantage of the customer is not connected
with these regulations.
