Earth fault monitoring
Earth Fault Relay
- Fault current switching threshold between 0.025 to 25A as freely selectable
- Switching time delay between 0.02 and 5 seconds as freely selectable
- With/without harmonic filter
As soon as a fault current (leakage current) occurs, the vectorial equilibrium will be disrupted and, as a result, a voltage will be induced in the secondary winding, which is then forwarded to the differential relay.
