Answer Posted / k.prakashchandra
The voltage and current measurements are fed to distance
relay.Z=V/I.During fault V decreases and I increases. Then
value of Z decreases.The relay is set to trip for a certain
low value of Z.So the relay does not trip at zero current
but at zero voltage.Connections are to be done as per the
instructions.
