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.

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 National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence be-
tween any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and ex-
penses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publica-
tions.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of pat-
ent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60034-18-1 has been prepared by IEC technical committee 2:
Rotating machinery.
This second edition cancels and replaces the first edition, published in 1992, and its amend-
ment 1 published in 1996, and constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
– provides general guidelines for functional evaluation of different types of windings as be-
fore 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 qualifica-
tion principles moved to the subsequent parts;
– 4 – 60034-18-1 © IEC:2010
– details additional general aspects of functional evaluation, particularly the statistical pro-
cedure 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.
The text of this standard is based on the following documents:
FDIS Report on voting
2/1583/FDIS 2/1592/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
NOTE A list of cross-references of all IEC TC 2 publications can be found in the IEC TC 2 dashboard on the IEC
website.
The committee has decided that the contents of this amendment and the base publication will
remain unchanged until the stability date indicated on the IEC web site under
"http://webstore.iec.ch" in the data related to the specific publication. At this date, the publica-
tion will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
