Relaying Protection Tester TPJB-III


General Introduction

TPJB-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. Its a low cost, simple operation and reliable performance device for secondary circuit test.
