(Main)Evaluation and qualification of electrical insulation systems
Evaluation and qualification of electrical insulation systems
Establishes the basis for estimating the ageing of electrical insulation systems (EIS) under conditions of either electrical, thermal, mechanical, environmental stresses or combinations of these (multifactor stresses). It specifies the principles and procedures that should be followed, during the development of EIS functional test and evaluation procedures, to establish the estimated service life for a specific EIS. The main changes with respect to the previous edition concern the amalgamation of the following standards, which, with the exception of EN 60727-1, will be withdrawn when this third edition is published: EN 60791:1984, Performance evaluation of insulation systems based on experience and functional tests EN 60792-1:1985, The multi-factor functional testing of electrical insulation systems - Part 1: Test procedures EN 60941:1988, Mechanical endurance functional tests for electrical insulation systems EN 61356:1995, Functional evaluation of electrical systems - Principles for test procedures when comparative testing is not feasible EN 61359:1995, Evaluation and identification of electric insulation systems - Environment evaluation EN 60727-1: 1982, Evaluation of electrical endurance of electrical insulation systems - Part 1: General considerations and evaluation procedures based on normal distributions Elements of EN 60727-1 that are not amalgamated will be considered in the next edition of that standard.

Evaluation et qualification des systèmes d'isolation électrique
Etablit les bases de l'estimation du vieillissement des systèmes d'isolation électrique (SIE) dans des conditions de contraintes électriques, thermiques, mécaniques, environnementales ou de combinaisons de ces contraintes (contraintes multifactorielles). Elle spécifie les principes et les procédures qu'il convient de suivre, au cours du développement d'essais fonctionnels ou de méthodes d'évaluation des SIE, pour établir la durée de vie estimée d'un SIE spécifique. Par rapport à l'édition précédente, cette édition est le résultat d'un regroupement des normes suivantes qui, à l'exception de la EN 60727-1, seront annulées à la publication de la présente troisième édition. EN 60791:1984, Evaluation des performances des systèmes d'isolation à partir de l'expérience en service et des résultats d'essais fonctionnels EN 60792-1:1985, Essais fonctionnels à plusieurs facteurs de systèmes d'isolation électrique - Première partie: Procédures d'essai EN 60941:1988, Essais fonctionnels d'endurance mécanique des systèmes d'isolation électrique EN 61356:1995, Evaluation fonctionnelle des systèmes d'isolation électrique - Principes de procédures d'essai lorsque l'essai comparatif n'est pas possible EN 61359:1995, Evaluation et identification des systèmes d'isolation électrique - Evaluation de l'environnement EN 60727-1:1982, Evaluation de l'endurance électrique des systèmes d'isolation électrique - Première partie: Considérations générales et procédures d'évaluation basées sur une distribution normale Les éléments de la EN 60727-1 qui ne sont pas regroupés dans la présente norme seront pris en compte dans la prochaine édition de la EN 60727-1.
