M13873-3 v12
Power swings may occur after disconnection of heavy loads or trip of big
generation plants.
Power swing detection function (ZMRPSB ) is used to detect power swings and
initiate block of all distance protection zones. Occurrence of earth-fault currents
during a power swing inhibits the ZMRPSB function, to allow fault clearance.
