PRT-PC3 China Best Price Single Phase Secondary Current Injection Tester 3 Three Phase Protection Relay 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.
PRT-PC3 S 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.
