Phase Reversal Relay

Phase sequence failure or phase reversal in a three phase induction motor can be dangerous when the opposite direction not allow in certain applications like Non reversing gear box, Screw Compressors, Certain Specialized Pumps, Blower fan etc. In certain cases it hazards to operating personnel. Phase reversal in a motor feeder produces a negative sequence of nearly 100% and is well detected by a relay with negative sequence / Phase Reverse protection.
