Insulation co-ordination - Part 1: Definitions, principles and rules
IEC 60071-1:2019 is available as IEC 60071-1:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60071-1:2019 applies to three-phase AC systems having a highest voltage for equipment above 1 kV. It specifies the procedure for the selection of the rated withstand voltages for the phase-to-earth, phase-to-phase and longitudinal insulation of the equipment and the installations of these systems. It also gives the lists of the standard withstand voltages from which the rated withstand voltages are selected. This document describes that the selected withstand voltages are associated with the highest voltage for equipment. This association is for insulation co-ordination purposes only. The requirements for human safety are not covered by this document. Although the principles of this document also apply to transmission line insulation, the values of their withstand voltages can be different from the standard rated withstand voltages. The apparatus committees are responsible for specifying the rated withstand voltages and the test procedures suitable for the relevant equipment taking into consideration the recommendations of this document. NOTE In IEC 60071-2, all rules for insulation co‑ordination given in this document are justified in detail, in particular the association of the standard rated withstand voltages with the highest voltage for equipment. When more than one set of standard rated withstand voltages is associated with the same highest voltage for equipment, guidance is provided for the selection of the most suitable set. The main changes from the previous edition are as follows: - all references are updated to current IEC standards, and the bibliography is deleted; - some definitions are clarified in order to avoid overlapping and ensure clear understanding; - letter symbols are changed and corrected in order to keep the consistency with relevant IEC standards; - some titles are changed to clarify understanding (see Clauses A.2, A.3 and Annex B).
Isolationskoordination - Teil 1: Begriffe, Grundsätze und Anforderungen
Coordination de l'isolement Partie 1: Définitions, principes et règles
IEC 60071-1:2019 est disponible sous forme de IEC 60071-1:2019 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 60071-1:2019 s'applique aux réseaux à tension alternative triphasée dont la tension la plus élevée pour le matériel est supérieure à 1 kV. Elle spécifie la procédure à suivre pour le choix des tensions de tenue assignées normalisées pour l'isolation phase-terre, l'isolation entre phases et l'isolation longitudinale du matériel et des installations de ces réseaux. Elle donne également les listes des valeurs normalisées parmi lesquelles les tensions de tenue assignées normalisées sont choisies. Le présent document décrit que les tensions de tenue choisies sont associées aux tensions les plus élevées pour le matériel. Cette association est destinée aux seules fins de la coordination de l'isolement. Les exigences concernant la sécurité des personnes ne sont pas couvertes par le présent document. Bien que les principes du présent document s'appliquent également à l'isolation des lignes de transport d'énergie, les valeurs des tensions de tenue peuvent être différentes des tensions de tenue assignées normalisées. Il appartient aux comités de produits de spécifier les tensions de tenue et les procédures d'essai appropriées aux matériels correspondants, en prenant les recommandations du présent document en considération. NOTE Toutes les règles relatives à la coordination de l'isolement données dans le présent document sont justifiées en détail dans l'IEC 60071-2, en particulier en ce qui concerne l'association des tensions de tenue assignées normalisées avec les tensions les plus élevées pour le matériel. Lorsque plusieurs séries de tensions de tenue assignées normalisées sont associées à la même valeur de la tension la plus élevée pour le matériel, une ligne directrice est donnée pour le choix de la série la plus appropriée. Les principales modifications par rapport à l'édition précédente sont les suivantes: a) toutes les références ont été mises à jour en faveur des normes IEC actuelles et la bibliographie est supprimée; b) certaines définitions ont été modifiées afin d'éviter les chevauchements et de favoriser une bonne compréhension; c) les symboles littéraux ont été modifiés et corrigés afin de garantir la cohérence avec les normes IEC concernées; d) plusieurs titres ont été modifiés en vue d'une meilleure compréhension (voir les Articles A.2 et A.3, ainsi que l'Annexe B).
