Anotation

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. The content of the corrigendum 1 (2025-04) has been included in this copy. LIEC 62271-214:2024 specifie les exigences relatives a la classification arc interne des appareillages sous enveloppe metallique a courant alternatif montes sur poteau, de tensions assignees superieures a 1 kV et inferieures ou egales a 52 kV, et de frequences de service inferieures ou egales a 60 Hz. Le present document sapplique aux equipements a bornes ouvertes triphases, biphases et monophases auxquels une classification arc interne est attribuee. Les enveloppes peuvent comprendre des composants fixes et amovibles et peuvent etre remplies de fluide (liquide ou gaz) pour lisolation. Cette deuxieme edition annule et remplace la premiere edition parue en 2019. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) mise a jour du positionnement des indicateurs; b) connexion de mise a la terre du neutre du circuit dessai pour les essais triphases; c) revision generale a des fins de coherence avec lIEC 62271-200 Ed.3.0:2021. Le contenu du corrigendum 1 (2025-04) a ete pris en consideration dans cet exemplaire.
