Phase-Sequence Relay | How it works, Application & Advantages
WEBOct 26, 2023 · The phase-sequence relay operates based on the order of the incoming voltage phases (A, B, and C) in a three-phase system. It detects the correct phase rotation (A-B-C or R-S-T) and ensures that the connected equipment operates within the designated phase sequence.
What is a Phase Sequence Relay? | How does it work?
WEBOct 29, 2021 · A phase sequence relay is a protective relay. 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.
