Secondary Injection Relay Test Set

Introduction
GDJB-III Secondary Injection Relay Test Set is used for test of relay protection device in high and low voltage power supply system. It can finish calibration of kinds of relay, check secondary circuit, check transformer, test trip value of circuit breaker, measure switch on and off time of circuit breaker and so on. It's of high precision, simple operation, reliable performance
