What is power system protection?

Power system protection refers to the practices, equipment, and systems used to detect and isolate faults or abnormal conditions in electrical power systems. The main goal is to protect people, equipment, and ensure reliable power supply by quickly identifying and disconnecting faulty sections of the network. This is typically achieved using devices such as relays, circuit breakers, and protective relaying schemes. Proper power system protection improves safety, minimizes equipment damage, and reduces outage times.
