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

IEC 60034-18-1:2010 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. The main changes of this new edition with respect to the previous one are as follows: - provides general guidelines for functional evaluation of different types of windings as before but beyond that for electrical evaluation of windings which are electrically stressed by converter-supply; - is now focused on general guidelines with all technical details of procedures and qualification principles moved to the subsequent parts; - details additional general aspects of functional evaluation, particularly the statistical procedure for comparison between reference and candidate insulation systems and the evaluation of minor component or manufacturing changes; - contains a new acceptance test for verifying the expected production quality level of the insulation systems; - restricts the classification of insulation systems as a result of the functional evaluation to thermal classification.

Machines électriques tournantes - Partie 18-1: Evaluation fonctionnelle des systèmes d'isolation - Principes directeurs généraux

La CEI 60034-18-1:2010 traite des principes directeurs généraux d'évaluation fonctionnelle des systèmes d'isolation électrique, utilisés ou que l'on se propose d'utiliser dans les machines électriques tournantes entrant dans le domaine d'application de la CEI 60034-1, en vue de leur qualification. Cette nouvelle édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - comme auparavant, fournit des recommandations générales pour l'évaluation fonctionnelle de différents types d'enroulements mais aussi au-delà, pour l'évaluation fonctionnelle des enroulements qui subissent une contrainte électrique du fait d'une alimentation par convertisseur; - met l'accent sur des recommandations générales, tous les détails techniques des procédures et des principes de qualification étant déplacés vers les parties concernées; - détaille des aspects généraux supplémentaires de l'évaluation fonctionnelle, particulièrement la procédure statistique pour dresser la comparaison entre les systèmes d'isolation candidat et de référence, ainsi que l'évaluation des changements mineurs de composants et de procédé de fabrication; - contient un nouvel essai d'acceptation pour la vérification du niveau de qualité de production visé pour le système d'isolation; - comme résultat de l'évaluation fonctionnelle, restreint la classification du système d'isolation à la classification thermique.

This European Standard supersedes EN 60034-18-1:1994 + A1:1996.
This EN 60034-18-1:2010 includes the following significant technical changes with respect to
EN 60034-18-1:1994 + A1:1996:
– provides general guidelines for functional evaluation of different types of windings as before but
beyond that for electrical evaluation of windings which are electrically stressed by converter-supply;
– is now focused on general guidelines with all technical details of procedures and qualification
principles moved to the subsequent parts;
– details additional general aspects of functional evaluation, particularly the statistical procedure for
comparison between reference and candidate insulation systems and the evaluation of minor
component or manufacturing changes;
– contains a new acceptance test for verifying the expected production quality level of the insulation
systems;
– restricts the classification of insulation systems as a result of the functional evaluation to thermal
classification. Other kinds of classifications (classes) of insulation systems no longer exist.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent
rights.
The following dates were fixed:

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 interna-
tional 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, Techni-
cal 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 organiza-
tions liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Or-
ganization 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 inter-
ested 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 misinter-
pretation by any end user.
4) In order to promote international uniformity, IEC Natio
