Relay protection voltage and current increase

Over voltage protection relays detect when the current's voltage exceeds a preset value. The entire system will shut down. Systems involving the transfer of electricity often use over voltage relays to prevent. A practical guide to how protective relays detect faults, trip circuit breakers, coordinate protection zones, and improve power system reliability. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions. It prevents safety hazards and damage to equipment.
