Key Points of Power Relay Protection

Protective relays are power system protection devices that monitor current, voltage, frequency, impedance, or differential quantities and command circuit breakers when faults or abnormal conditions occur. Engineering use: Relays are used on feeders, transformers, buses, motors, generators, and transmission lines to protect equipment and improve system. Protective relays can be classified based on their operating principle, construction, or function: 1. Based on Operating Principle Electromechanical Relays: Work using moving parts and electromagnetic forces (traditional relays). Static Relays: Use electronic components without moving parts. Protective relays and devices have been developed over 100 years ago to provide “last line” of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions. This prevents damage to equipment, reduces downtime, and safeguards.
