PRT-PC3 Microcomputer relay protection tester 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.
It 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.
