Universal Three Phase Relay Protection Tester Secondary Current Injection Test Set


Relay Protection Tester

Three phase relay protection tester

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 Relay Protection Tester 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.

  • The standard output of 4 phases of voltage and 3 phases of current  

  • It could combine various type of current or voltage conveniently and has diversity type of protective experiment. Every phase of voltage output is 120V, and the total of the parallel current is 120A. The fourth phase voltage Ux has many functions and it can be set to be 4 type of every three voltages or synchronism checking voltage, or output any value of voltage

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