EN 61857-1:2009

Electrical insulation systems - Procedures for thermal evaluation - Part 1: General requirements - Low-voltage

IEC 61857-1:2008 specifies a general test procedure for the thermal evaluation and qualification of electrical insulation systems (EIS) and establishes a procedure that compares the performance of a candidate EIS to that of a reference EIS. This standard is applicable to existing or proposed EIS used in electrotechnical products with an input voltage of up to 1 000 V where the thermal factor is the dominating ageing factor. This third edition cancels and replaces the second edition published in 2004, and constitutes editorial revisions to make this standard compatible with Parts 21 and 22.

Elektrische Isoliersysteme - Verfahren zur thermischen Bewertung - Teil 1: Allgemeine Anforderungen - Niederspannung

Systèmes d'isolation électrique - Procédures d'évaluation thermique - Partie 1: Exigences générales - Basse tension

La CEI 61857-1:2008 spécifie une procédure d'essai générale pour une évaluation thermique et une qualification des systèmes d'isolation électrique (SIE), et établit une procédure comparant la qualité de fonctionnement d'un SIE candidat à celle d'un SIE de référence. Cette norme s'applique aux SIE existants ou proposés, utilisés dans les produits électrotechniques dont la tension d'entrée monte jusqu'à 1 000 V pour lesquels le facteur thermique est le facteur de vieillissement prépondérant. Cette troisième édition annule et remplace la seconde édition publiée en 2004, et elle constitue une révision rédactionnelle pour rendre la présente norme compatible avec les Parties 21 et 22.
