The ES-47 Phase Sequence Relay monitors a three-phase, three-wire system for correct phase rotation/sequence. It provides protection against incorrect phase sequence, phase loss, and undervoltage. ES-47 relays operate on only the fundamental component of the sensed voltage, rejecting all harmonic components.
