Rotating electrical machines - Part 2-2: Specific methods for determining separate losses of large machines from tests - Supplement to IEC 60034-2-1
IEC 60034-2-2:2024 applies to large rotating electrical machines and establishes additional methods of determining separate losses and to define an efficiency supplementing IEC 60034‑2‑1. These methods apply when full-load testing is not practical and results in a greater uncertainty. The specific methods described are: - Calibrated-machine method. - Retardation method. - Calorimetric method. - Summation of losses for permanent magnet excited synchronous machines. This second edition cancels and replaces the first edition published in 2010. This edition includes the following significant technical changes with respect to the previous edition: - Layout and procedures aligned with IEC 60034-2-1 and IEC 60034-2-3. - Annex A added: an informative procedure for the summation of losses for large permanent-magnet excited synchronous machines.

L'IEC 60034-2-2:2024 s'applique aux machines électriques tournantes de grande taille et établit des méthodes supplémentaires pour la détermination des pertes séparées et qui sont destinées à définir un rendement, en complément de l'IEC 60034‑2‑1. Ces méthodes s'appliquent lorsqu'un essai à pleine charge n'est pas possible ou qu'il présente une plus grande incertitude. Les méthodes spécifiques décrites sont: - la méthode de la machine étalonnée; - la méthode du ralentissement; - la méthode calorimétrique; - la sommation des pertes pour les machines synchrones avec une excitation à aimants permanents. Cette deuxième édition annule et remplace la première édition parue en 2010. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) alignement de la disposition et des procédures sur l'IEC 60034-2-1 et l'IEC 60034-2-3; b) ajout de l'Annexe A: procédure informative pour la sommation des pertes des machines synchrones de grande taille avec une excitation à aimants permanents.

ROTATING ELECTRICAL MACHINES –
Part 2-2: Specific methods for determining
separate losses of large machines from tests –
Supplement to IEC 60034-2-1
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 60034-2-2 has been prepared by IEC technical committee 2:
Rotating machinery.

5 Supplement to IEC 60034-2-1
9 1 Scope
10 This part of IEC 60034 applies to large rotating electrical machines and establishes additional
11 methods of determining separate losses and to define an efficiency supplementing
12 IEC 60034-2-1. These methods apply when full-load testing is not practical and result in a
13 greater uncertainty.
14 NOTE In situ testing according to the calorimetric method for full-load conditions is recognized.
15 The specific methods described are:
16 – Calibrated-machine method.
17 – Retardation method.
18 – Calorimetric method.
19 – Summation of losses for permanent magnet excited synchronous machines.
