EN 61000-4-11:2004

Electromagnetic compatibility (EMC) - Part 4-11: Testing and measurement techniques - Voltage dips, short interruptions and voltage variations immunity tests

This part of EN 61000 defines the immunity test methods and range of preferred test levels for electrical and electronic equipment connected to low-voltage power supply networks for voltage dips, short interruptions, and voltage variations. This standard applies to electrical and electronic equipment having a rated input current not exceeding 16 A per phase, for connection to 50 Hz or 60 Hz a.c. networks. It does not apply to electrical and electronic equipment for connection to 400 Hz a.c. networks. Tests for these networks will be covered by future IEC standards. The object of this standard is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to voltage dips, short interruptions and voltage variations. This second edition cancels and replaces the first edition published in 1994 and its amendment 1 (2000). This second edition constitutes a technical revision in which 1) preferred test values and durations have been added for the different environment classes; 2) the tests for the three-phase systems have been specified. It has the status of a Basic EMC Publication in accordance with IEC Guide 107.

Elektromagnetische Verträglichkeit (EMV) - Teil 4-11: Prüf- und Messverfahren - Prüfungen der Störfestigkeit gegen Spannungseinbrüche, Kurzzeitunterbrechungen und Spannungsschwankungen

Compatibilité électromagnétique (CEM) - Partie 4-11: Techniques d'essai et de mesure - Essais d'immunité aux creux de tension, coupures brèves et variations de tension

La présente partie de la EN 61000 définit les méthodes d'essai d'immunité ainsi que la gamme des niveaux d'essais préférés pour les matériels électriques et électroniques connectés à des réseaux d'alimentation basse tension pour les creux de tension, les coupures brèves et les variations de tension. La présente norme s'applique aux matériels électriques et électroniques dont le courant nominal d'entrée ne dépasse pas 16 A par phase et destinés à être reliés à des réseaux électriques alternatifs de 50 Hz ou 60 Hz. Elle ne s'applique pas aux matériels électriques et électroniques destinés à être reliés à des réseaux électriques à courant alternatif de 400 Hz. Les essais pour ces réseaux seront traités dans des normes CEI à venir. Le but de cette norme est d'établir une référence commune pour l'évaluation de l'immunité fonctionnelle des matériels électriques et électroniques soumis à des creux de tension, à des coupures brèves et à des variations de tension. Cette deuxième édition annule et remplace la première édition parue en 1994 et son amendement 1 (2000). Cette deuxième édition constitue une révision technique dans laquelle 1) des durées et niveaux d'essai préférés pour les différentes classes d'environnement ont été ajoutées ; 2) les essais pour les systèmes triphasés ont été précisés. Elle a le statut de publication fondamentale en CEM conformément au Guide 107 de la CEI.

Elektromagnetna združljivost (EMC) – 4-11. del: Preskusne in merilne tehnike – Preskusi odpornosti proti upadom napetosti, kratkotrajnim prekinitvam in napetostnim kolebanjem (IEC 61000-4-11:2004)

Ta del standarda IEC 61000 določa metode preskušanja odpornosti in obseg najprimernejših preskusnih nivojev za električno in elektronsko opremo, ki je priključena na nizkonapetostna električna omrežja za upade napetosti, kratke stike in spremembe napetosti.
Ta standard velja za električno in elektronsko opremo z nazivnim vhodnim tokom, ki ne presega 16 A na fazo, za priključitev na omrežja z izmeničnim napajanjem 50 Hz ali 60 Hz.
Ne uporablja se za električno in elektronsko opremo, za priključitev na omrežja z izmeničnim tokom 400 Hz.
Preskusi za ta omrežja bodo zajeti v prihodnjih standardih Mednarodne elektrotehniške komisije (IEC).
Namen tega standarda je določiti skupno referenco za vrednotenje odpornosti električne in elektronske opreme na upade napetosti, kratke stike in spremembe napetosti.
OPOMBA Preskusi odpornosti pri spremembi napetosti so zajeti v standardu IEC 61000-4-14.
Preskusna metoda, dokumentirana v tem delu standarda IEC 61000, opisuje skladno metodo za oceno odpornosti opreme ali sistema proti opredeljenemu pojavu. To je osnovna objava o elektromagnetni združljivosti, ki jo uporabljajo tehnični odbori v okviru Mednarodne elektrotehniške komisije, kot je opisano v vodilu 107 Mednarodne elektrotehniške komisije. Poleg tega je v vodilu 107 navedeno, da so tehnični odbori v okviru Mednarodne elektrotehniške komisije odgovorni za določitev morebitne uporabe tega standarda s preskusom odpornosti, v primeru uporabe pa so odgovorni za določitev ustreznih preskusnih ravni. Tehnični odbor 77 in njegovi pododbori so pripravljeni za sodelovanje s tehničnimi odbori pri vrednotenju posameznih preskusov odpornosti za ustrezne izdelke.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 61000-4-11 has been prepared by subcommittee 77A: Low
frequency phenomena, of IEC technical committee 77: Electromagnetic compatibility.
This second edition cancels and replaces the first edition published in 1994 and its amendment
1 (2000). This second edition constitutes a technical revision in which
1) preferred test values and durations have been added for the different environment classes;
2) the tests for the three-phase systems have been specified.
It forms part 4-11 of IEC 61000. It has the status of a Basic EMC Publication in accordance
with IEC Guide 107.
