Universal Three Phase Secondary Current Injection Test Set

secondary injection test

Introduction:

  • GDJB-PC Universal Three Phase Secondary Current Injection Test Set 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.

  • GDJB-PC Universal Three Phase Secondary Current Injection Test Set is applied to test protection replay based on voltage and current operation.

  • The main function of the tester include: 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.

  • It’s a low cost, simple operation and reliable performance device for secondary circuit test.
