Answer Posted / rajdip thakur
Earth fault relay trips when the current through the neutral exceeds a preset value.Simply it acts on the superposition theorem. Whether the vector sum of the phase current and the neutral current are same or not.If not then it operates.
But the earth leakage circuit breaker operates when some current flows from neutral to ground. We know that the voltage difference between neutral and ground is zero.It operates only when there appears some voltage.

please tell me, how i clear the objective test? when i studied form the one book after i solved the objective ,that time i solved that qes. but if i tried solve objective form the other book then i could not solved these que.
In EDO ACBs what is a purpose of closing coil and motor, what is the operation of these devices are they inetconnected. means if we give supply to motor and by BCS we charge Closing coil,what exact is operation is and how it charge a spring of ACB. Sir if anybody has an wiring diagram please send me the link to operate and EDO breaker.
