High voltage switchgear consists of switching devices, protective relays, and associated control equipment used to isolate, protect, and control electrical circuits operating above 1,000 volts. These assemblies include circuit breakers, disconnect switches, fuses, and instrument transformers housed in metal-enclosed or metal-clad configurations. Industrial facilities rely on high voltage switchgear to manage incoming utility feeds, distribute power to substations, and provide fault protection across the electrical system.
