product real picture
1. Application
GDJB-PC AC/DC Voltage Source or Current Source/Relay Tester is applied to test the relay unit in relay protection system.
At the same time GDJB-PC relay tester could be considered as a universal three phase AC/DC voltage source or current source.
2. Functions
1) AC current and voltage based protection relay unit test
2) DC current and voltage based protection relay unit test
3) Frequency protection relay unit test
4) Harmonic protection relay unit test
5) Differential protection relay unit test
6) Zero-sequence protection relay unit test
7) Distance protection relay unit test
8) Power system network fault simulation
