Unique Advantages
Conventional circuit breakers use complicated
mechanisms to transfer actions from a single actuator
into the movements of three arc quenching contacts.
Beyond this, the movable contacts are fixed in their
OPEN and CLOSED positions through the use of
mechanical latches. These mechanical arrangements
are subject to severe stresses at C-O operations and are
the main reason for circuit breaker failures.
Tavrida Electric has simplified this mechanical
structure to the greatest possible degree. The ISM
vacuum circuit breaker uses three single-coil magnetic
actuators, one per pole. All the switching elements are
assembled along a single axis. All mechanical
movements are therefore direct and linear. The three
actuators are mounted in a steel frame and
mechanically linked by a synchronizing shaft.
Failure of critical components, such as
• mechanical latching
• gears, chains, bearings and levers
• tripping and closing coils
• motors to charge springs are completely avoided.
Highly Reliable Drive Mechanism
Top Availability & Reliability
Maximizing the benefits of the driving mechanism
requires vacuum interrupters that combine small
dimensions with an extraordinary long mechanical and
electrical lifespan.
The use of a predefined axial magnetic field provides
even distribution of current density and consequently
substantial improvement of vacuum interrupting
performance.
Selected contact material and special contact design
together with optimized movement and switching
speed result in bounce-free closing.
Substantial increase in mechanical lifespan as well as
size reduction of Tavrida Electric vacuum
interrupters was achieved by utilizing metal bellows
consisting of single discs as opposed to the
conventional use of folded steel.
This has resulted in 50 000 (150 000 at response) C-O
cycles at rated current or 100 operations at full short
circuit breaking current without the need to replace or
adjust any parts of the ISM.
Tavrida Electric´s vacuum circuit breaker are
maintenance free over the total life expectancy of at
least 30 years.

Interlocks
The draw-out unit provides all the interlocks needed to
guarantee the high level of safety and reliability both
for the installation commissioning and operation.
Standard safety interlocks
• The draw-out unit can only be moved if the ISM is
open and locked.
• The ISM can only be unlocked and operated if the
draw-out unit is precisely in the test or service
position.
• The electromechanical interlocks can only be
unlocked and operated if the draw out unit is
precisely in the test or service position.
Interlocks connected with switchgear (the draw-out unit inserted into switchgear)
• The draw-out unit can only be moved when the earth
switch is open.
• The earth switch can only be closed when the
draw-out unit is in test/disconnected position.
• The draw-put unit can only be moved if bus bars
in Switchgear are not earthed (electrical interlock on
request)

An arc fault instantaneously releases large amounts of
energy. Arcing time is a critical factor in limiting the
damage and risk of personal injury resulting from an
arc flash. The total arching time is determined by both
relay response time and circuit breaker opening times.
One Cycle Interruption -Reducing Arc Flash Hazards
One Cycle Interrupcion
Arc Flash Safety
The energy released in an arc fault is directly
proportional to the total clearing time. Whilst relay
response times have improved, medium voltage
circuit breaker opening times are usually as long as
five cycles!
Tavrida circuit breakers are designed with the entire
concept in mind – optimizing vacuum interrupter,
insulation, magnetic actuator and control modules.
This has resulted in the fastest circuit breaker, the one
cycle interrupter - a breakthrough for fast switching
and arc flash protection technology.
Once the circuit breaker receives the trip signal from
an arc-flash relay, it is able to interrupt in twelve
milliseconds (HD ISM with CM/TEL-100/220-15-01(S))
to provide increased arc flash hazard mitigation – the
fastest arc fault interruption in the industry – helping
to reduce work-related injuries, fatalities and lost
productivity.
Tavrida circuit breakers are fully compatible with
standard arc-flash relays such as the SEL 751A.
Voltage decreases or complete supply interruptions
represent the most important and critical problems
for the quality of energy supply today. It is especially
true that voltage disturbances with electronic control
systems and other sensitive installations can lead to
complete loss of production and long stoppage time.
Possible areas of utilization include, for example:
Auxiliary installations serving power stations
• Steam power stations
• Gas turbine power stations
• Combined cycle power stations
• Nuclear power stations
Environmental technology installations
• Flue gas purification
• Refuse incineration installations
Voltage supply to continuous industrial processes
• Chemical plants
• Industrial facilities with high degrees of automation
• Fiber manufacturing
• Petrochemical processes
Fast Automatic Transfer
In order to realize a permanent availability, the load
is supplied from at least two synchronized feeders
which are independent from one another and which are
equipped with High Speed Transfer Devices. In doing
so, the High Speed Transfer Device has the task of
ensuring uninterrupted continuous operation of the
connected devices in case of a power supply
breakdown, taking into account different physical
factors, through the most rapid possible transfer to a
different feeder kept stand-by.
The typical decay characteristics (voltage and
frequency) of a disconnected busbar and the possible
closing moments are shown in the figure.

The execution of fast transfers is the most preferred.
A fast transfer takes place when the both the main and
the stand-by feeder are within specified limit values
at the moment of initiation, e.g. that slip and phase
angle are limited between the networks and the
stand-by voltage lies above a minimum value. Here the
open and close commands to the circuit-breaker from
the High Speed Transfer Device are issued
synchronously. The current-free transfer time occurring
in this case for the users is exclusively dependent upon
the difference between the operating time for closing
and opening the circuit breakers concerned.
Tavrida circuit breakers are designed in a way to
provide both trip and close time minimal in the
industry. Complete changeover can take no more than
50ms with a proper digital relay, for example SUE 3000
or SEL 571, with a current free transfer time (dead
time) 12ms.
An exemplary oscillogram of a fast transfer caused by
main feeder fault with dead time of approximately 20
ms is shown in the figure.

In case of power supply failure the TEL manual
generator MG/TEL-80/110-40-01 can be used as
reserve power supply for control module installed on
Draw-out unit.
This optional amendment allows having an opportunity
of performing emergence close operation at any time
independently from availability of
standard or emergency power supply system and
allows to increase reliability and applicability of the
TEL vacuum circuit breakers sufficiently.

When purchasing equipment various cost criteria have
to be evaluated, the so called Life Cycle Cost (LCC).
LCC studies measure the impact of a system or project
on long term budgets and its operating impact. The
studies examine factors such as product purchase cost,
maintenance cost, non-availability cost and design
parameters.
The moment you buy, you decide what total cost you
will be facing throughout the life cycle!
• Thanks to its large number of switching operations,
the ISM remains in service longer than any other
vacuum circuit breaker.
• Compact switchgear solutions not only help save
material costs but also provide additional cost
savings because of reduced space requirements.
• Highest availability reduces down-time to an
absolute minimum.
• It is maintenance-free, thus reducing overall costs
drastically.
