Answer Posted / dolphin
earth leakage relay sense leakage current using troide
around 5 wires (R,S,T,N,E) or earth wire only and give its
signal for protection relay which protect this power cable
feeder.
restricted earth fault make protection for predifined and
determined zone, always protect primary or secondary of
transformer or both of them through no. of 3 ct at power
lines and 1 ct at star point of transformer which connected
to earth so it protect winding of transformer and zone till
ct's.
