Nettet1. mar. 2024 · Automated protective switchgear consists of a relay and circuit breaker. The relay acts whenever there is a fault. The relay closes the faulty circuit and disconnects the disrupted line. This ensures that the appliances do not get damaged and there is an uninterrupted supply of power. Substations generally have switching, protection and control equipment, and transformers. In a large substation, circuit breakers are used to interrupt any short circuits or overload currents that may occur on the network. Smaller distribution stations may use recloser circuit breakers or fuses for protection of distribution circuits. Substations themselves do not usually have generators, although a po…
