Electromagnetic compatibility (EMC) - Part 3-5: Limits - Limitation of voltage fluctuations and flicker in low-voltage power supply systems for equipment with rated current greater than 75 A
IEC/TS 61000-3-5:2009 deals with emission of disturbances due to voltage fluctuations and flicker. The recommendations in this Technical Specification are applicable to electrical and electronic equipment that has a rated input current exceeding 75 A per phase and is intended to be connected to a public low-voltage a.c. distribution system. Recommendations that specify information enabling a supply authority, manufacturer, or consumer to assess equipment are given in Annex A. This second edition cancels and replaces IEC 61000-3-5, published as Technical Report type 2 in 1994 and constitutes a technical revision. It includes the following significant technical changes with respect to the previous edition: the whole document and the title have been modified to eliminate any conflict with the published IEC 61000-3-11. The contents of the corrigenda of September 2009 and May 2010 have been included in this copy.
Compatibilité électromagnétique (CEM) - Partie 3-5: Limites - Limitation des fluctuations de tension et du flicker dans les réseaux basse tension pour les équipements ayant un courant appelé supérieur à 75 A
La CEI/TS 61000-3-5:2009 porte sur l'émission de perturbations de type fluctuations de tension et papillotement. Les recommandations figurant dans cette Spécification Technique sont applicables aux appareils électriques et électroniques dont le courant assigné d'entrée est supérieur à 75 A par phase et qui sont destinés à être raccordés à un réseau public de distribution basse tension. Les recommandations qui précisent les informations nécessaires pour permettre à une compagnie d'électricité, un constructeur ou un consommateur d'évaluer un matériel sont données dans l'Annexe A. Cette deuxième édition annule et remplace la CEI 61000-3-5, publiée comme Rapport Technique de type 2 en 1994 et constitue une révision technique. Elle inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: le document dans son ensemble et le titre ont été modifiés pour éliminer tout conflit avec la CEI 61000-3-11 publiée. Le contenu des corrigenda de septembre 2009 et mai 2010 a été pris en considération dans cet exemplaire.

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.
The main task of IEC technical committees is to prepare International Standards. In
exceptional circumstances, a technical committee may propose the publication of a technical
specification when
• the required support cannot be obtained for the publication of an International Standard,
despite repeated efforts, or
• the subject is still under technical development or where, for any other reason, there is the
future but no immediate possibility of an agreement on an International Standard.
Technical specifications are subject to review within three years of publication to decide
whether they can be transformed into International Standards.
IEC/TS 61000-3-5, which is a technical specification, has been prepared by subcommittee
77A: Low frequency phenomena of IEC technical committee 77: Electromagnetic compatibility.
– 4 – TS 61000-3-5 © IEC:2009
This second edition cancels and replaces IEC 61000-3-5, published as Technical Report
type 2 in 1994 and constitutes a technical revision.
It includes the following significant technical changes with respect to the previous edition: the
whole document and the title have been modified to eliminate any conflict with the published
IEC 61000-3-11.
The text of this technical specification is based on the following documents:
Enquiry draft Report on voting
77A/681/DTS 77A/693/RVC
Full information on the voting for the approval of this technical specification 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.
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in
the data related to the specific publication. At this date, the publication will be
• transformed into an International standard,
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
The contents of the corrigenda of September 2009 and May 2010 have been included in this
copy.

INTRODUCTION
IEC 61000 is published in separate parts according to the following structure:
Part 1: General
General considerations (introduction, fundamental principles)
Definitions, terminology
Part 2: Environment
Description of the environment
Classification of the environment
Compatibility levels
Part 3: Limits
Emission limits
Immunity limits
(in so far as they do not fall under the responsibility of product committees)
Part 4: Testing and measurement techniques
Measurement techniques
Testing techniques
Part 5: Installation and mitigation guidelines
Installation guidelines
Mitigation methods and devices
Part 6: Generic standards
Part 9: Miscellaneous
Each part is further subdivided into several parts published either as International Standards
or as technical specifications or technical reports, some of which have already been published
as sections. Others will be published with the part number followed by a dash and a second
number identifying the subdivision (example: 61000-6-1).
IEC/TS 61000-3-5
This Technical Specification is presented as an informative document as it is already a
requirement, in most countries, for equipment having a rated input current exceeding 75 A per
phase to be subject to assessment and connection by the public supply network operator.
Therefore, it is not intended, at the time of publication, to be converted into an
