Rotating electrical machines - Part 18-1: Functional evaluation of insulation systems - General guidelines

This part of IEC 60034 deals with the general guidelines for functional evaluation of electrical insulation systems, used or proposed to be used in rotating electrical machines within the scope of IEC 60034-1, in order to qualify them.

Drehende elektrische Maschinen - Teil 18-1: Funktionelle Bewertung von Isoliersystemen - Allgemeine Richtlinien

Machines électriques tournantes - Partie 18-1: Évaluation fonctionnelle des systèmes d'isolation - Lignes directrices générales

L’IEC 60034-18-1:2022 traite des lignes directrices générales pour l'évaluation fonctionnelle des systèmes d'isolation électrique, utilisés ou dont l'utilisation est proposée dans les machines électriques tournantes relevant du domaine d'application de l'IEC 60034-1, en vue de leur qualification. L’IEC 60034-18-1 définit les exigences générales pour la qualification des systèmes d’isolation, dans lesquels, pour le vieillissement thermique, les équations d’Arrhenius ne sont pas nécessairement adaptées, comme cela ressort de nombreux retours d’expérience. Cette troisième édition annule et remplace la deuxième édition parue en 2010. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a. comme auparavant, fournit des lignes directrices générales pour l'évaluation fonctionnelle de différents types d'enroulements, mais inclut les modifications qui ont été introduites pour la qualification et l'évaluation électriques des enroulements qui subissent une contrainte électrique du fait d'une alimentation par convertisseur; b. met désormais l'accent sur les lignes directrices générales, tous les détails techniques des procédures et des principes de qualification étant déplacés vers les parties subséquentes; c. décrit des aspects généraux supplémentaires de l'évaluation et de la qualification fonctionnelles, en particulier la procédure de comparaison entre les systèmes d'isolation candidat et de référence, l'introduction du concept de qualification pour différentes durées de vie en service prévues, ainsi que l'évaluation des changements mineurs de composants ou de processus de fabrication.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any d
