The function of earth fault relay is to to protect the
device from earth fault. there are 2 types of earth fault
fault relays
1.neutral ct conneted earth fault relay. it will sense the
current flowing through neutral while earth lerakage.
2.three phase ct's connected earth fault relay.in normal
condition the sum of three phase ct's current in zero.
when earth fault the sum of the 3 phase ct's curret are un
balanced that time relay acts.
