NettetPhase Sequence Relays. The phase sequence relay/guard measure three phase AC supplies for correct rotation and will activate and relay output for any fault. A wrong phase sequence will cause fault in rotation or motors and pumps and can cause problems and damages. The units also monitor for phase failure and phase imbalance in the supply.
