Protective Relay Systems
Reliable real-time protection and control for critical power systems. Ensure operational safety, minimize downtime, and maintain system integrity with our advanced protective relay systems.
Tailored solutions for diverse sectors and challenges.
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.
