WebNov 9, 2024 · A blocking of the earth fault scheme at distance protection operation is often used to enable use of short time delays in the communicating earth fault relays. During a single phase trip an unbalance in the complete network occurs and an earth fault currents flows through the network. WebDistance protection is widely applied in High/Ultra-High Voltage AC transmission system. Impedance relay, the core element of distance protection, may operate incorrectly under power swing, so a power swing blocking unit is needed in distance protection. In this paper, the phase difference between the measurement voltage and compensation ... WebDec 10, 2015 · The Directional Comparison Blocking scheme that is available in the D60 is one of the most popular types of tele-protection schemes used in distance applications today. The purpose of the scheme is to still speed up the tripping of faults that occur in the end zone of a transmission line, just like the POTT scheme. graphite private equity logo
