Product Profile of Primary Current Injection Sets

R.R. Enterprises manufactures Primary Current Injection Sets. The Primary Current Injection Sets is designed to operate on single phase 230/240 volts AC 50 HZ to develop smooth & continuous test current as for loading, calibrating, and testing of CTs, Bimetal Relays, Protection Relays etc. The test set gives high current output at low cost and with inherent safety .The primary current injection testing checks all parts of the protection system by injecting current down the cable/bus bars.

R.R. Enterprises supplies various types of High Voltage Test equipments & Measuring instruments. The application of the primary current injection sets is to ascertain the current carrying capacity of any Conductor, insulator, connector or calibration of CTs / bi-metallic relays etc.
