Pott scheme relaying

WebThe Relay Testing Handbook: End-to-End Testing covers the most common Communication-Assisted Protection Schemes including the Permissive Over-Reaching Transfer Trip (POTT) Scheme. This bonus animation shows the steps involved for a POTT trip. Webscheme is known as a POTT. Since the signalling channel is keyed by overreaching Zone 2 elements, the scheme requires duplex communication channels [4]. To prevent the relay from operating under current reversal conditions in parallel feeder circuit, a current reversal guard timer must be used to restrain tripping
