Switchgear - Wikipedia

High-voltage switchgear was invented at the end of the 19th century for operating motors and other electric machines. The technology has been improved over time and can now be used with voltages up to 1,100 kV. Typically, switchgear in substations are located on both the high- and low-voltage sides of large power transformers. The switchgear on the low-voltage side of the transformers may be located in a building, with medium-voltage circuit breakers for distribution circuits, along withGet price

The 4 most common switchgear-based substation types

Open air substations. Open air substations contain separately mounted and interconnected switching equipment and components, like current transformers (CTs), voltage transformers (VTs), busbar support insulators, cable sealing ends, etc., where atmospheric air provides the main insulation path to earth. Metal enclosed. With metal enclosed arrangement all switching devices and associated components are enclosed in a metallic earthed structure on a per-bay basis and are cable connected. Metal-clad. This is a derivative of the metal-enclosed switchgear where all major components per bay are physically segregated from one another by means of earthed metalwork such that a fault in any one compartment cannot readily spread to adjacent compartments. Gas-insulated substations (GIS) A further form of metal-clad substation that is used mainly at transmission voltages is the gas-insulated substation.
