Web9 Jan 2012 · As mentioned above, POTT scheme relies on receiving a “permission to trip” signal from the remote-end relay and the local relay to initiate a breaker trip. The signal is … WebWithout a pilot protection scheme, faults at the ends of the line would require time delayed relay operation to isolate faults. A POTT scheme is intended to provide 100% line coverage for faults on the protected transmission line. There are several conditions that require a modification in the POTT scheme to provide dependability.
