Product Description

GDJB-II Single phase Relay Protection Tester(Secondary Current/Voltage Injection Tester) 


Product Description

GDJB-II relay protection calibrator is a new generation of calibration device developed by our company. The AC/DC voltage and current source inside the instrument adopts the latest power supply technology, which makes the instrument reach the domestic advanced level in circuit design, device selection, panel layout and internal structure design. The instrument has the advantages of perfect functions, excellent material selection, clear test project data, simple operation, etc. It is the preferred equipment for the power conservation department.

1. Measuring relay: It can measure the starting value, return value and return coefficient of current and voltage relay.
2. Time relay: It can measure the starting value, return value and its action time.
3. Intermediate relay: It can measure the starting value, return value, holding value and operating time of various intermediate relays with starting coil and holding coil.
4. Reclosing relay: Capacitor charging test, charging time, reclosing time and intermediate component test.
5. Differential relay: DC excitation test, braking characteristic test, volt-ampere characteristic test.
