PRODUCT PROFILE
CURRENT TRANSFORMER
Our all the Epoxy Resin Cast Instrument Transformers & Epoxy Cast Components are
Manufactured through Automatic Machine.
APPLICATION –Direct measurement of current in high voltage & high current system is not possible because of
difficulty in electrical isolation of measuring instruments. Because of its high value,it is also not possible to use current flowing
directly to the system, so that current transformer are used to step down the high system current into low system measuring
current with their proportionate ratio. due to this it is possible to measure high system current by using standard measuring
instruments & relays, also its isolate meters,relays from high voltage systems.
VARIOUS TYPES OF CURRENT TRANSFORMERS
Ring T ype Current Transformers : A Current Transformer which has an window
in the center to accommodate a primary conductor (busbar or cable) through it.
Bar -Primar y Current Transformers : A Current Transformer in which the
primary winding consists of bar of suitable size and it is an integral part of the CT.
Wound T ype Current Transformers : A Current Transformer having a primary
winding of more than one full turn wound on the core.
Interposing Current Transformers : These Current Transformers are used in
conjunction with main CTs to alter the ratio of main CT or to provide isolation to
meters or relays from main CTs secondary circuit. Primary current of these CTs
are generally lower than 1 0 amp. Due to which they are always wound primary
type.
Summation Current Transformers : W hen current flowing, in more than one
feeder is required to be metered summation current transformer are used. These
Current Transformers are provided with more than one primary winding and one
common secondary.
Bushing T ype or Busduct Current Transformers : These Current
Transformers are Ring type construction & can be mounted on Busduct or
Bushing turrert of power transformer.
Core Balance Current Transformers : These are ring type Current
Transformers & suitable for the measurement of the sum of three phase currents
in a 3-ph cable. Under normal operating conditions this sum is zero. In the event
of an earth-fault the sum of the current is equal to the zero sequence current.

COMBINED CTPT SET
APPLICATION- Combined CTPT Metering Units that are available up to 33 kV class are manufactured specifically to
meet the needs of Electricity Supply and captive generating units. The C.T.-P.T. metering sets of this type as the name
suggests are used for measurement of power on high voltage side. The C.T.-P.T. sets are installed before the main
transformer and the main line goes through C.T.-P.T. set to the main transformer. Metering equipment is connected to the
secondary side of the C.T.-P.T. set. As the accuracy of the C.T.-P.T. set is high & as it is connected before the transformer,
measurement of power is much more accurate compared to the metering done on L.T. side, the transformer losses are
also included in the measurement.
