Switchgear is a collection of electrical devices used to control, protect, and isolate electrical equipment in power systems. It includes components like circuit breakers, fuses, and switches, which help manage the flow of electricity and ensure safety in electrical networks. Switchgear can be found in various settings, from industrial plants to residential buildings, and is essential for maintaining reliable power supply. The primary function of switchgear is to interrupt fault currents and prevent damage to electrical systems. By isolating faulty sections, it allows for safe maintenance and reduces the risk of electrical hazards. Properly designed switchgear contributes to the overall efficiency and safety of electrical installations, making it a critical component in modern energy management.
