WebA POTT scheme is intended to provide high speed isolation for all faults on 100% of the protected transmission line. It is very dependent on the permissive signal and will not operate if the signal is lost. Dependability of the POTT Scheme is limited when the permissive signal drops out due to communications channel noise. WebCalifornia State University

WebA POTT scheme communicates Zone 2 information between relays. If either relay detects a Zone 2 fault, it will send a signal to the other relay. If the other relay also detects a Zone 2 fault, the fault MUST be between the two relays, and there is no reason to delay in this case.
