Nice explanation. How current is flowing through relay during in zone fault since there is a stabilizing resistor connected in that path?

thank you so much. What about the low impedance ref prot? using the numerical relays? are the CT secondary currents converted in pu and the rest concept is the same?

Sir , u have explained neatly high imp ref . But after that low imped ref with numerical relay not explained sir .please EXPLAIN separately . we have 15mva tf , NCT , ALSTOM RELAY and there is no such circuits present near my relay wat u have explained in your vedio. We just fed NCT terminals to relay terminals separately and power side CT are fed separately to numerical relay . . How I can incorporate ur ckt with this numerical relay .

For REF, connect them in such a way that they cancel out each other, so that in normal condition, no current flows through the REF relay coil.
