A protection relay is an electrical device that automatically disconnects a faulty part of an electrical power system to prevent damage to equipment and maintain power supply to healthy sections of the system. It operates by monitoring various electrical parameters, such as current, voltage, and frequency, and comparing them to set values. If a fault is detected, the relay triggers a switch to isolate the faulty portion of the system, allowing the rest of the system to continue functioning normally. Protection relays play a critical role in ensuring the stability and reliability of electrical power systems and preventing equipment damage and power outages.
