Edition date: 2022-06-29
In Force
Available languages: Spanish, English, French
Summary: IEC 62271-212;2022 specifies the service conditions, rated characteristics, general structural requirements and test methods of the assemblies of the main electrical functional units of a high-voltage transformer substation, duly interconnected, for AC voltages up to and including 52 kV on the high-voltage side and service frequency 50 Hz or 60 Hz. The CEADS is cable‑connected to the high-voltage network for indoor and outdoor applications of restricted access. This second edition cancels and replaces the first edition published in 2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- clause numbering aligned with IEC 62271-1:2017,
- rewording of title and scope of the document,
- implement changes on internal arc definition and testing following the evolution of prefabricated substation concept according to IEC 62271-202,
- general review of main test procedures such as temperature rise or dielectric test on interconnections, considering control equipment, communication, smart grid devices and integration of components,
- general review of installation, operation, safety and maintenance requirements.

L'IEC 62271-212:2022 spécifie les conditions de service, les caractéristiques assignées, les exigences structurelles générales et les méthodes d'essai des ensembles des principales unités fonctionnelles électriques d'un poste de transformation haute tension, dûment interconnecté, pour les tensions alternatives inférieures ou égales à 52 kV du côté haute tension, et avec une fréquence de service de 50 Hz ou 60 Hz. L’ECEPD est raccordé par câble au réseau à haute tension pour des applications à l’intérieur et à l’extérieur à accès restreint. Cette deuxième édition annule et remplace la première édition parue en 2016. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
