Answer Posted / raghavendran.r
Distance protection relays work on the value of Z = V/I.
Whenever there is a fault, the value of I increases and
thus the value of Z is reduced.It is by this vakue of
impedance the relay senses the distance of the fault from
its location.
It is also called as Ohmic method of Protection.
