We manufacture resin cast summation CT s which summates the current in a number of feeders in association with feeder current transformers.'When current flows in more than one feeder is required to be metered summation current transformer are used. These CTs are provided with more than one primary winding and one common secondary. The standard primary & secondary currents are 5 or 1 amp. Summation current transformers are generally manufacture-confirming to ISS 6949.

We manufacture Core balance or Zero sequence (Tape or Resin Cast ) CTs. These are  for sensitive earth leakage protection and earth fault protection. These are suitable for Bus bar of panels/ bus duct and cables etc.These are ring or rectangular type CTs & 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. It is necessary to specify leakage current to be detected along with minimum setting of the relay and size of cable at the time of ordering CT.

Primary Current :

300 mA to 10 A

We manufacture control transformers that are designed with very low temperature rise and ensure excellent voltage regulation. These also ensure extreme overload capacity of high momentary in-rush current demand by the contractors, relays and solenoids. The output voltage drop under high momentary in-rush current is also very low, which ensures satisfactory operation of contactors, relays and solenoids.
