Relay Protection Tester

GDJB-PC Three-Phase Relay Protection Tester





      1.GDJB-PC Universal Secondary Injection Relay Test Set is applied to test the relay unit in relay protection system.

      2.At the same time GDJB-PC Universal Secondary Injection Relay Test Set could be considered as a universal three phase AC/DC voltage source or current source.

      3.It can work alone or connected to computer, inside the relay controller there are new speed digital signal mini PC and real DAC (Digital-to-Analog Converter) template with new high fidelity and high power, the machine has large panel screen and rotating mouse. It is small in volume, high precision.
