Permissive overreaching transfer trip

WebA large number of variants have been developed, from the permissive underreaching transfer trip (PUTT) to the permissive overreaching transfer trip (POTT), all of which have their justification depending on their use. Before commissioning distance protection with communication, it is absolutely necessary to know, understand, and test the method ... WebThe “Permissive overreaching transfer trip” scheme (POTT) is intended for two-terminal line applications only. It uses an over-reaching zone 2 distance element to essentially compare the direction to a fault at both the ends of the line.
