Annotation of standard text IEC 62271-203-ed.2.0 :
IEC 62271-203:2011 specifies requirements for gas-insulated metal-enclosed switchgear in which the insulation is obtained, at least partly, by an insulating gas other than air at atmospheric pressure, for alternating current of rated voltages above 52 kV, for indoor and outdoor installation, and for service frequencies up to and including 60 Hz. This second edition of IEC 62271-203 cancels and replaces the first edition of IEC 62271-203, published in 2003, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:- adopting the structure and the content to IEC 62271-1,- harmonisation with IEEE C37.122,- addition of the new Annex F and the new Annex G.This publication is to be read in conjunction with IEC 62271-1:2007. The contents of the corrigendum of July 2013 have been included in this copy. La CEI 62271-203:2011 specifie les exigences pour lappareillage sous enveloppe metallique a isolation gazeuse dont lisolation est realisee, au moins partiellement, par un gaz isolant autre que lair a la pression atmospherique, pour courant alternatif de tensions assignees superieures a 52 kV, pour linstallation a linterieur et a lexterieur, et pour des frequences de service inferieures ou egales a 60 Hz. Cette deuxieme edition de la CEI 62271-203 annule et remplace la premiere edition de la CEI 62271-203 publiee en 2003, et constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente:- adoption de la structure et du contenu de la CEI 62271-1,- harmonisation avec lIEEE C37.122,- ajout de la nouvelle Annexe F et de la nouvelle Annexe G.Cette publication doit etre lue conjointement avec la CEI 62271-1:2007. Le contenu du corrigendum de juillet 2013 a ete pris en consideration dans cet exemplaire.
