Primary Current Injection Test Sets are used to loading, Calibration and testing of CT's bimetals relays, Protection relays etc. Mostly Primary Injection Test set are designed as per customer's specification. The Primary Injections Test sets are of 15 minutes ON/30Minutes OFF duty i.e. testing duty only. Loading transformers are design for continuous use for Temperature Rise or bus duct/Bus Bar etc. Optional accessories requirement may include cable termination, timer, Temperature Indicator, multiple contactor, individual Phase control etc. Equipments are Compact in nature. It is available in portable trolley type/stationery type model Amps. Optional digital/analogue timer. Main Transformer up to 25,000Amps.
