Phase Sequence Relay | Phase Failure Relay | Over Voltage & Under Voltage Protection Relay

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. A Phase Failure Relay is a phase-voltage-balance monitoring device designed for use with magnetic contactors to automatically prevent three phase motors or other equipment from operating or attempting to start up under open phase or single-phase conditions, thereby eliminating burnouts and consequent down-time .. Phase unbalance means the three phases of a three-phase supply are not all of equal magnitude – for example here one phase (red) is larger than the other two: Phase unbalance can occur either on the voltage or on the current – or most likely, on both. Over voltages are the voltages that exceed the normal or rated values which cause insulation damage to electrical appliances leading to short circuits. Similarly, under-voltage causes overloading of the equipment leading to lamp flickers and inefficient performance of the equipment.
