Aparataj de înaltă tensiune. Partea 200: Aparataj în carcasă metalică, pentru curent alternativ şi tensiuni nominale peste 1 kV şi până la 52 kV inclusiv
IEC 62271-200:2011 specifies requirements for prefabricated metal enclosed switchgear and controlgear for alternating current of rated voltages above 1 kV and up to and including 52 kV for indoor and outdoor installation, and for service frequencies up to and including 60 Hz. Enclosures may include fixed and removable components and may be filled with fluid (liquid or gas) to provide insulation. This second edition cancels and replaces the first edition, published in 2003. It is a technical revision. This second edition of IEC 62271-200 has been further updated and improved to the experience gained with the first edition of IEC 62271-200. As maintenance result, this second edition of IEC 62271-200 introduces the following significant changes: - definitions, classifications and testing procedures are specified more precisely; - categories LSC2A and LSC2B have been clarified and LSC2 has been assigned a separate definition; - specific ratings related to fault level to earth (4.5 to 4.7) are introduced; - solid insulated high-voltage parts are no longer considered as compar
