Rotating electrical machines - Part 18-32: Functional evaluation of insulation systems - Test procedures for form-wound windings - Evaluation of electrical endurance of insulation systems used in rotating electrical machines (IEC 60034-18-32:2010)
This part of IEC 60034-18 describes test procedures for the evaluation of electrical endurance of insulation systems for use in a.c. or d.c. rotating electrical machines using form-wound windings. The test procedures are comparative in nature, such that the performance of a candidate insulation system is compared to that of a reference insulation system with proven service experience. The test procedures are principally directed at the insulation systems in air-cooled machines but may also be used for evaluating parts of the insulation systems in hydrogen cooled machines. Note that the qualification procedures of inverter duty insulation systems for form-wound windings can be found in IEC 60034-18-42.

Ta del IEC 60034-18 opisuje preskusne postopke za električno vrednotenje izolacijskih sistemov za uporabo za električne rotacijske stroje izmeničnega ali enosmernega toka, ki uporabljajo predhodno oblikovana navitja. Preskusni postopki so primerljivi glede značilnosti, tako da se zmogljivost možnega izolacijskega sistema primerja z referenčnim izolacijskih sistemom s preizkušenim servisiranjem. Preskusni postopki so zlasti usmerjeni k izolacijskim sistemom v zračno hlajenih strojih, vendar se lahko uporabijo tudi za vrednotenje delov izolacijskih sistemov v strojih, ki so hlajeni z vodikom. Upoštevajte, da se kvalifikacijski postopki za obvezne izolacijske sisteme razsmernikov za predhodno oblikovana navitja nahajajo v IEC 60034-18-42.

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 divergence
between 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
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
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
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60034-18-32 has been prepared by IEC technical committee 2:
Rotating machinery.
This first edition cancels and replaces IEC/TS 60034-18-32, published in 1995 and constitutes
a technical revision.
The main technical changes with regard to the previous technical specification are as follows.
a) simplification of clauses;
b) reduction in the number of test procedures;
c) inclusion of full bars and coils as test objects;
d) a new clause dealing with failures and failure criteria.

INTRODUCTION
Part 1 of IEC 60034-18 presents general principles for the evaluation of insulation systems
used in rotating electrical machines.
This standard deals exclusively with insulation systems for form-wound windings and
concentrates on electrical functional evaluation.

Test procedures for form-wound windings –
Evaluation by electrical endurance
1 Scope
This part of IEC 60034-18 describes test procedures for the evaluation of electrical endurance
of insulation systems for use in a.c. or d.c. rotating electrical machines using form-wound
windings. The test procedures are comparative in nature, such that the performance of a
candidate insulation system is compared to that of a reference insulation system with proven
service experience. The test procedures are principally directed at the insulation systems in
air-cooled machines but may also be used for evaluating parts of the insulation systems in
hydrogen cooled machines. Note that the qualification procedures of inverter duty insulation
systems for form-wound windings can be found in IEC 60034-18-42.

3.5
stress grading material

4 General considerations
4.1 Relationship to Part 1 of IEC 60034-18
The principles of Part 1 of IEC 60034-18 should be followed unless the recommendations of
this International Standard indicate otherwise.
4.2 Selection and designation of test procedures
One or more of the procedures in this International Standard should be suitable for the
majority of evaluations. Evaluation is usually performed by the manufacturer of the
machine/coils or by a third party laboratory. It is the manufacturer’s responsibility to justify the
most suitable procedure in Table 1 on the basis of past experience and knowledge of the
insulation systems to be compared.
The test procedure should be selected from Table 1 and designated by IEC 60034-18-32
procedure N, where N is the designation given in the Table 1. Subclauses 4.3, 4.4 and 4.5
