WebTransmission line protection Since the impedance of a transmission line is proportional to its length, for distance measurement it is appropriate to use a relay capable of measuring the impedance of a line up to a predetermined point. Such a relay is called distance relay ( 21 ). f Transmission line protection

This … holding back tears emoji discordWebIts a Direct trip signal, hence Direct Transfer Trip. This adds extra protection and speed ( at a price) to the line. POTT, permissive overreach transfer trip, has the same communication line between the relays. In this scheme though, the relay that sees a zone 2 fault will ask for permission from the other relay to trip. holding back tearsWebA permissive overreach transfer tripping (POTT) logic is also implemented in this model.
