What is BS EN 62271 ‑ 201 ‒ AC solid-insulation enclosed switchgear /controlgear about?
BS EN 62271 ‑ 201 is a part of an international multi-series standard that covers general specifications for high-voltage switchgear and control gear.
BS EN 62271 ‑ 201 specifies requirements for prefabricated solid-insulation enclosed switchgear and controlgear for alternating current of rated voltages above 1 kV and up to and including 52 kV for indoor installation and for service frequencies up to and including 60 Hz.
BS EN 62271 ‑ 201 supplements the standards for the individual components regarding their installation in switchgear and control gear assemblies. Components contained in solid-insulation enclosed switchgear and controlgear are designed and tested in accordance with their various relevant standards.
BS EN 62271 ‑ 201 is also applicable to switching devices having disconnecting and/or earthing functionalities apart from other functions, such as high-speed earthing switch, circuit-breaker, and switch-disconnector.
