EN 61857-1:1999
(Main)Electrical insulation systems - Procedures for thermal evaluation - Part 1: General requirements - Low-voltage
Electrical insulation systems - Procedures for thermal evaluation - Part 1: General requirements - Low-voltage
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. Is applicable to existing or proposed EISs used in electrotechnical products with an input voltage of up to 1 000 V where the thermal factor is the dominating ageing factor.
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
Spécifie une procédure d'essai générale pour une évaluation thermique et une qualification des systèmes d'isolation électriques (SIE), et établit une procédure comparant la qualité de fonctionnement d'un système d'isolation électrique candidat à celle d'une système électrique de référence. S'applique aux systèmes d'isolation électriques 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.
