Phase monitoring relays

Phase sequence and phase loss sensors (relays) are designed to protect electric motors powered from a three-phase network. The sequence and phase failure relay detects events that may result in damage to the motor, such as a voltage failure in one or more phases or the occurrence of voltage imbalance between phases. Phase sequence relays also detect incorrect phase sequence of the power supply, thus preventing the motor from rotating in the wrong direction.
