High-voltage switchgear and controlgear - Part 214: Internal arc classification for AC metal-enclosed pole-mounted switchgear and controlgear for rated voltages above 1 kV and up to and including 52 kV
IEC 62271-214:2024 specifies requirements for internal arc classification of AC metal-enclosed pole-mounted switchgear and controlgear with rated voltages above 1 kV and up to and including 52 kV with service frequencies up to and including 60 Hz. This document is applicable to three-phase, two-phase and single-phase open terminal equipment for which an internal arc classification is assigned. 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 2019. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) indicators positioning update; b) neutral earthing connection of the test circuit for three-phase tests; c) general review for consistency with IEC 62271-200, Ed.3.0:2021.

Appareillage à haute tension - Partie 214 : Classification arc interne des appareillages sous enveloppe métallique à courant alternatif de tensions assignées supérieures à 1 kV et inférieures ou égales à 52 kV montées sur poteau
L'IEC 62271-214:2024 spécifie les exigences relatives à la classification arc interne des appareillages sous enveloppe métallique à courant alternatif montés sur poteau, de tensions assignées supérieures à 1 kV et inférieures ou égales à 52 kV, et de fréquences de service inférieures ou égales à 60 Hz. Le présent document s'applique aux équipements à bornes ouvertes triphasés, biphasés et monophasés auxquels une classification arc interne est attribuée. Les enveloppes peuvent comprendre des composants fixes et amovibles et peuvent être remplies de fluide (liquide ou gaz) pour l'isolation. Cette deuxième édition annule et remplace la première édition parue en 2019. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) mise à jour du positionnement des indicateurs; b) connexion de mise à la terre du neutre du circuit d'essai pour les essais triphasés; c) révision générale à des fins de cohérence avec l'IEC 62271-200 Éd.3.0:2021.
Visokonapetostne stikalne in krmilne naprave - 214. del: Razvrščanje notranjih oblokov pri stikalnih in krmilnih napravah AC, nameščenih na kovinskih drogovih, za naznačene napetosti nad 1 kV do vključno 52 kV (IEC 62271-214:2024)
Standard IEC 62271-214:2024 določa zahteve za razvrščanje notranjih oblokov pri stikalnih in krmilnih napravah na izmenični tok, nameščenih na kovinskih drogovih, z naznačeno napetostjo nad 1 kV do vključno 52 kV in s frekvencami delovanja do vključno 60 Hz. Ta dokument se uporablja za trifazno, dvofazno in enofazno terminalsko opremo odprtega tipa, za katero je dodeljeno razvrščanje notranjih oblokov. Okrovi lahko zajemajo fiksne in premične dele in so lahko za izolacijo napolnjeni s tekočino (kapljevino ali plinom). Druga izdaja razveljavlja in nadomešča prvo izdajo, objavljeno leta 2019. Ta izdaja je tehnično popravljena izdaja. Ta izdaja v primerjavi s prejšnjo vključuje naslednje pomembne tehnične spremembe:
a) posodobitev položajev kazalnikov;
b) nevtralna ozemljitev preskusnega tokokroga za trifazne preskuse;
c) splošen pregled skladnosti s standardom IEC 62271-200, izdaja 3.0:2021.
