Answer Posted / biju poulose
An earth leakage relay will sense and trip the circuit for
any earth leakage fault that may occur any where in the
system. The C.T provided at the neutral bus is used for
sensing this fault.
A restricted earth fault relay will operate only for earth
leakage that occur in a zone which is determined by a group
of C.T's connected antiparallel to the neutral C.T.
