Earth fault monitoring
Earth Fault Relay
Fault current and earth fault monitoring significantly increases the plant safety.
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.
- 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

For protection and monitoring of electrical installations:
combined with an automatic tripping device, they ensure protection for personnel and equipment. As a preventive measure, they also signal the appearance of earthing faults.
