PRIMARY INJECTION TEST SETS

Primary 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/30 Minutes OFF duty i.e. testing duty only. Loading transformers are design for continuous use for Temperature Rise for bus duct/Bus Bar etc.

Optional accessories requirement may include cable termination, timer, Temperature Indicator, multiple contactor, individual Phase control etc.
