I agree with Mr.Ravikumar except in one point.
If the load distribution of a 3 phase 4 wire system is not
balanced in all three phases, there will be some potential
in neutral wire and thus a current flow also.
In this condition, if the neutral wire touches to earth
after the earth fault relay CT, definitely this E/F relay
will sense this current flow from neutral to earth and thus
trip the circuit.
If any other disagreement, please mail me at

Thank you.
