Battery earth fault relay - JRC 082
Features
- Software based design
- Instantaneous / Definite time
- Wide range of battery voltage
- Solid state reliability
Application:
The relay monitor the battery and ensure that no leakagebetween battery and ground in DC systems.
Principle of Operation:
The relay measures the leakage current between battery and earth if the current increased more than the set value the relay trips as per time delay setting . The relay output contacts are hand reset type. Relay operation without any fault current is determined by trip test facility.
