This relay is used on AC systems and is a sensitive electronic protective device. Its operation on Earth fault is independent of the system voltage imbalance. This relay can detect Earth fault currents as low as 1 amp. This is 0.25% in a 400 amps feeder system. This can be used on a single phase or on a three-phase network.
