Protection Relay Three Phase Secondary Current Injection Test Set

I.Introduction:

This secondary injection test kit is applied to test the relay unit in relay protection system. At the same time it could be considered as a universal three phase AC/DC voltage source or current source.

This relay protection tester is applied to test protection replay based on voltage and current operation.

The main function of 3 phase relay test set includes: calibration of voltage and current operation relays, secondary circuit inspection,trip value of circuit breaker test, switch on and off time measurement of circuit breaker and so on.

This secondary injection kit is a low cost, simple operation and reliable performance device for secondary circuit test.
