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. WebA Permissive scheme tells the other relay that it is allowed to trip faster if it ALSO detects a fault in the correct direction. Both relays must agree that there is a fault before a Permissive trip, unlike the direct scheme that would send a trip … root tear posterior horn medial meniscus
