what is the diff between earth leakage relay and earth
fault relay?
Answer Posted / tina john
Eath fault implies a significant contact between phase and ground and it can cause heavy current and can cause damage; earth leakage is a high resistance contact with earth that the phase may have in cables; devices etc.; since the current is small it wont create any problem usually. However, its a sort of indication that there are insulation problems present in the cable/devices.
