| Title | High-voltage switchgear and controlgear - Part 200: AC metal-enclosed switchgear and controlgear for rated voltages above 1 kV and up to and including 52 kV |
| Project Number | 22850 |
| Abstract/Scope | 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 compartments on their own; - an optional rating 'cable test voltage' and the associated requirements and type tests are introduced; - for testing the internal arc classification, when assigned by the manufacturer, more specific guidance is provided regarding the test arrangement, room simulation and arc initiation; - a single phase to earth ignition is also recognised for internal arc testing; - the Annexes A and B are renumbered Annexes AA and BB. This publication is to be read in conjunction with IEC 62271-1:2007. |

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved
(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat
(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level
(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement
(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
