Shunt power capacitors of the self-healing type for a.c. systems having a rated voltage up to and including 1 000 V - Part 1: General - Performance, testing and rating - Safety requirements - Guide for installation and operation
IEC 60831-1:2014 is applicable to both capacitor units and capacitor banks intended to be used, particularly, for power-factor correction of a.c. power systems having a rated voltage up to and including 1 000 V and frequencies of 15 Hz to 60 Hz. This part of IEC 60831 also applies to capacitors intended for use in power filter circuits. Additional definitions, requirements, and tests for power filter capacitors are given in Annex A. The object of this part of IEC 60831 is to:
- formulate uniform rules regarding performances, testing and rating;
- formulate specific safety rules;
- provide a guide for installation and operation. This third edition cancels and replaces the second edition published in 1996 and Amendment 1:2002. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- Updating of the normative references;
- Test conditions have been clarified;
- Thermal stability test has been clarified;
- Maximum permissible voltage and current have been clarified;
- The protection of the environment has been amended with safety concerns and plastic quality requirements.
The contents of the corrigendum of May 2014 have been included in this copy.
Condensateurs shunt de puissance autoregénérateurs pour réseaux à courant alternatif de tension assignée inférieure ou égale à 1 000 V - Partie 1: Généralités - Caractéristiques fonctionnelles, essais et valeurs assignées - Règles de sécurité - Guide d'installation et d'exploitation
IEC 60831-1:2014 s'applique aux condensateurs unitaires et aux batteries de condensateurs autorégénérateurs destinés plus particulièrement à la correction du facteur de puissance des réseaux à courant alternatif de tension assignée inférieure ou égale à 1 000 V et de fréquence comprise entre 15 Hz et 60 Hz. Cette partie de la CEI 60831 s'applique également aux condensateurs destinés à être utilisés dans des circuits de filtrage. Les définitions, les exigences et les essais complémentaires pour les condensateurs de filtrage en courants forts sont indiqués dans l'Annexe A. La présente partie de la CEI 60831 a pour objet:
- de formuler des règles uniformes pour les performances, les essais et les caractéristiques assignées;
- de formuler des règles spécifiques de sécurité;
- de fournir un guide pour l'installation et l'utilisation. Cette troisième édition annule et remplace la seconde édition parue en 1996 et l'Amendement 1:2002. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- mise à jour des références normatives;
- clarification des conditions d'essai;
- clarification de l'essai de stabilité thermique;
- clarification de la tension maximale et du courant maximal autorisés;
- modification des mesures de sécurité et des exigences en matière de qualité du plastique pour la protection de l'environnement. Mots clés: condensateurs unitaires et aux batteries de condensateurs autorégénérateurs, règles uniformes pour les performances, essais et les caractéristiques assignées règles spécifiques de sécurité; guide pour l'installation et l'utilisation. Le contenu du corrigendum de mai 2014 a été pris en considération dans cet exemple.
