Annotation of standard text IEC 62146-1-ed.2.0 :
IEC 62146-1:2026 is available as IEC 62146-1:2026 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 62146-1:2026 includes generalities of capacitors used on alternating current circuit-breakers and introduces specifications for grading capacitors. Regarding grading capacitors, their function is to control the voltage distribution across the individual interrupter units of a multi-break circuit-breaker. This document applies to grading capacitors falling into one or both of the following categories for: - mounting on air-insulated circuit-breakers. - mounting on enclosed circuit-breakers (for example immersed in insulating gas, in oil, etc.). The object of this document is: - to define uniform rules regarding performances, testing and rating; - to define specific safety rules; - to provide a guidance for installation and operation. This document does not apply to capacitors not directly associated with high-voltage alternating current circuit-breakers. IEC 62146-1:2026 est disponible sous forme de IEC 62146-1:2026 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l°dition pr°c°dente.L’IEC 62146-1:2026 expose des generalites concernant les condensateurs utilises sur les disjoncteurs a courant alternatif et presente des specifications relatives aux condensateurs de repartition. Les condensateurs de repartition ont pour fonction de controler la repartition de la tension entre chaque interrupteur dun disjoncteur a coupure multiple. Le present document sapplique aux condensateurs de repartition relevant de lune des categories suivantes, ou des deux: - condensateurs montes sur des disjoncteurs isoles dans l’air; - condensateurs montes sur des disjoncteurs proteges (par exemple, immerges dans du gaz isolant, dans lhuile, etc.). Lessai applicable a chacune des applications susmentionnees est different dans certains cas. Le present document a pour objet de: - definir des regles uniformes concernant les performances, les essais et les caracteristiques assignees; - definir des regles de securite specifiques; - fournir des recommandations pour l’installation et le fonctionnement. Le present document ne s’applique pas aux condensateurs qui ne sont pas directement associes aux disjoncteurs a courant alternatif haute tension.
