A phase-sequence relay monitors phase rotation in three-phase systems, protecting equipment from damage due to incorrect or reversed phase order. It guards a 3-phase device against any potential damage due to sequence change. They are deployed anywhere with a phase-sequence change that can damage the device or circuit. They work like a conventional electric relay. The order of these voltages is typically designated as ABC, where A, B, and C represent the phases. The correct phase sequence is vital for proper functioning and protection of various. Engineers use a Phase Failure Relay, which is additionally known as a Voltage Monitoring Relay (or) a Phase Sequence Relay to avoid costly breakdowns. This small but powerful equipment continuously monitors the state of the three-phase supply & guarantees that motors work only according to safe. A phase sequence relay is a tool that controls the correct sequence of phases in three-phase electrical systems.
