Power Relays Application Guide

This guide covers all of our true power relays as distinguished from directional power and direc-tional overcurrent relays. Its purpose is to pinpoint exactly the relay required for any specific appli-cation.

Protection Relay:Types, wiring diagram and working principle.

Protection relay is an electromechanical monitoring safety device which senses fault and provide trip signal to the breaker as per set value in LT and HT panel.

Protective Relay Basics

Traditionally, protective relays were electromechanical devices utilizing induction disk, coils, contacts, and solenoid elements to determine protective characteristics.
