automatic three phase relay protection tester Automatic Relay Test System

automatic three phase secondary injection tester

Introduction

• GDJB-PC 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 Three Phase 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.
