Primary Current Injection Test Sets are used to loading, Calibration, and testing of CT bimetals relays, Protection relays etc. Mostly Primary Injection Test set is designed as per customer specification. The Primary Injections Test sets are of 15 minutes ON/30Minutes OFF duty i.e. testing duty only. Loading transformers are designed for continuous use for Temperature Rise or bus duct/Bus Bar etc. Optional accessories requirement may include cable termination, timer, Temperature Indicator, multiple contractors, individual Phase control etc. Equipment is Compact in nature. It is available in portable trolley type/stationery type model And Optional digital/analog timer. Main Transformer up to 25,000Amps.
Electronic Parameter Monitoring.
Multiple safety interlocks for the operator.
Rugged in construction for site application.
