Voltage relays perform oversight functions on voltages, and shield a system from a preset threshold being crossed. Their primary purpose is to identify critical conditions such as under-voltage and over-voltage and initiate circuit disconnection, as well as alarming affected. Engineering use: Relays are used on feeders, transformers, buses, motors, generators, and transmission lines to protect equipment and improve system reliability. What controls it: Relay performance depends on the protected zone, CT/PT inputs, pickup settings, time delay, breaker clearing time, trip. The rectangular devices are test connection blocks, used for testing and isolation of instrument transformer circuits. In electrical engineering, a protective relay is a relay device designed to trip a circuit breaker when a fault is detected. Based on Operating Principle Electromechanical Relays: Work using moving parts and electromagnetic forces (traditional relays). Static Relays: Use electronic components without moving parts. It monitors voltage to determine if levels rise too high or dip too low.
