Answer Posted / rupali
EARTH LEAKAGE CIRCUIT BREAKER WORKS IF IT GETS ANY CURRENTS
ACROSS EARTHING & IT DETECTS CURRENT THROUGH THIS OPERATION:
WE KNOW THE VECTOR SUM OF THREE PHASES IS EQUAL TO NEUTRAL &
EQUALS TO ZERO.IF EARTH DETECTS ANY CURRENTS THEN THROUGH
NEUTRAL FLOWS SOME AMOUNT OF CURRENT AND THE ELCB TRIPS OUT.
