Secondary Injection Test Set HYJB-III

HYJB-III Relaying protection tester 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.
