Relays

The primary purpose of a relay is to protect the electrical system from too high of a voltage or current , allowing the safe operation of any equipment it connects to. They're commonly found in a variety of applications, from commercial and industrial uses to home and consumer products Electromechanical relays are used in motor control circuits, automotives, power systems, etc. Numerical relays are mainly used in generating stations and substations . Numerical relays can be programmed and that's what makes them a focal point of interest. When numerical protection relays are being used on a protection device, they provide accurate protection, better reliability, easy troubleshooting, communication, and fault information . Relays designed for the protection and control, of utility substations and industrial power systems, in primary and secondary distribution network
