High-voltage switchgear and controlgear - Part 203: Gas-insulated metal-enclosed switchgear for rated voltages above 52 kV
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.

Appareillage à haute tension - Partie 203: Appareillage sous enveloppe métallique à isolation gazeuse de tensions assignées supérieures à 52 kV
La CEI 62271-203:2011 spécifie les exigences pour l'appareillage sous enveloppe métallique à isolation gazeuse dont l'isolation est réalisée, au moins partiellement, par un gaz isolant autre que l'air à la pression atmosphérique, pour courant alternatif de tensions assignées supérieures à 52 kV, pour l'installation à l'intérieur et à l'extérieur, et pour des fréquences de service inférieures ou égales à 60 Hz. Cette deuxième édition de la CEI 62271-203 annule et remplace la première édition de la CEI 62271-203 publiée en 2003, et constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - adoption de la structure et du contenu de la CEI 62271-1, - harmonisation avec l'IEEE C37.122, - ajout de la nouvelle Annexe F et de la nouvelle Annexe G. Cette publication doit être lue conjointement avec la CEI 62271-1:2007.
Visokonapetostne stikalne in krmilne naprave - 203. del: Plinsko izolirane stikalne naprave v kovinskih ohišjih za naznačene napetosti nad 52 kV (IEC 62271-203:2011)
Ta del standarda IEC 62271 določa zahteve za plinsko izolirane stikalne naprave v kovinskih ohišjih, ki so vsaj delno izolirane z izolirnim plinom, drugačnim od zraka pri atmosferskem tlaku, za izmenični tok naznačenih napetosti nad 52 kV za notranjo ali zunanjo namestitev in za frekvence delovanja do vključno 60 Hz. Za namene tega standarda se za »plinsko izolirane stikalne naprave v kovinskih ohišjih« uporabljajta izraza »plinsko izolirane stikalne naprave (GIS)« in »stikalne naprave«. Plinsko izolirane stikalne naprave v kovinskih ohišjih, zajete v tem standardu, so sestavljene iz posameznih komponent, ki se neposredno medsebojno povežejo in lahko delujejo le na ta način. Ta standard po potrebi dopolnjuje in spreminja različne ustrezne standarde, ki veljajo za posamezne komponente plinsko izoliranih stikalnih naprav.
