WebDistance relay applications. Distance relays respond to the voltage and current, i.e., the impedance, at the relay location. The impedance per mile is fairly constant so these relays respond to the distance between the relay location and the fault location. As the power systems become more complex and the fault current varies with changes in ... WebThe master trip relay can operate as a hub of multiple protection relays trip commands and drive multiple subsequent contacts.
