Switchgear

A switchgear is an essential electrical device used to distribute and control electrical power. It serves the following main functions: First, it distributes the electricity generated from a power plant or substation to various loads (e.g., households, industrial machines, commercial buildings) in an appropriate manner. Second, it protects electrical equipment and people in case of abnormal electrical conditions such as overcurrent, overvoltage, or short circuits. This is achieved through components such as circuit breakers, fuses, and protective relays. Third, it controls and monitors the operation of electrical equipment. It includes switches, meters, and controllers, and can be remotely operated through automation systems. Fourth, it can transform voltage levels as needed to ensure efficient power utilization, using components such as transformers. With these functions, switchgear plays a vital role in ensuring stable and safe power supply.
