  • Is a relay protection device a primary device

    Is a relay protection device a primary device

    Primary relay or primary protection relay is the first line of power system protection whereas backup relay is operated only when primary relay fails to be operated during a fault. Core idea: Protective relays monitor electrical quantities and command protective devices to isolate faults or abnormal operating conditions. Its main purpose is to safeguard electrical equipment like transformers, generators, and transmission lines from damage due to. Electromechanical protective relays at a hydroelectric generating plant. The relays are in round glass cases.
