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 ... WebPermissive Overreaching Transfer Trip In the Permissive Overreaching Transfer Trip (POTT) scheme the permissive channel is keyed by the operation of the overreaching distance functions. Tripping is initiated only if the local overreaching distance functions detect a fault, and a per missive trip signal is r eceived from both remote terminals. impacthk
