EN 61000-3-3:2008

Electromagnetic compatibility (EMC) - Part 3-3: Limits - Limitation of voltage changes, voltage fluctuations and flicker in public low-voltage supply systems, for equipment with rated current <= 16 A per phase and not subject to conditional connection

IEC 61000-3-3:2008 is concerned with the limitation of voltage fluctuations and flicker impressed on the public low-voltage system. It specifies limits of voltage changes which may be produced by an equipment tested under specified conditions and gives guidance on methods of assessment. This part of IEC 61000 is applicable to electrical and electronic equipment having an input current equal to or less than 16 A per phase, intended to be connected to public low-voltage distribution systems of between 220 V and 250 V line to neutral at 50 Hz, and not subject to conditional connection. The tests according to this part are type tests. Particular test conditions are given in annex A and the test circuit is shown in Figure 1. This second edition IEC 61000-3-3 cancels and replaces the first edition published in 1994, amendment 1 (2001) and amendment 2 (2005). This edition constitutes a revised edition. NEW! IEC 61000-3-3:2008 is also available as IEC Standards+ 61000-3-3:2008 which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

Elektromagnetische Verträglichkeit (EMV) - Teil 3-3: Grenzwerte - Begrenzung von Spannungsänderungen, Spannungsschwankungen und Flicker in öffentlichen Niederspannungs-Versorgungsnetzen für Geräte mit einem Bemessungsstrom <= 16 A je Leiter, die keiner Sonderanschlussbedingung unterliegen

Compatibilité électromagnétique (CEM) - Partie 3-3: Limites - Limitation des variations de tension, des fluctuations de tension et du papillotement dans les réseaux publics d'alimentation basse tension, pour les matériels ayant un courant assigné <= 16 A par phase et non soumis à un raccordement conditionnel

La CEI 61000-3-3:2008 traite des limitations des fluctuations de tension et du flicker appliqués sur le réseau de distribution public basse tension. Elle spécifie les limites des variations de tension pouvant être produites par un équipement essayé dans des conditions spécifiées et formule des recommandations pour les méthodes d'évaluation. La présente partie de la CEI 61000 s'applique aux matériels électriques et électroniques ayant un courant appelé inférieur ou égal à 16 A par phase et destinés à être raccordés à des réseaux publics de distribution basse tension présentant une tension nominale phase-neutre comprise entre 220 V et 250 V à 50 Hz et non soumis à un raccordement conditionnel. Les essais effectués selon la présente partie sont des essais de type. Les conditions d'essai pour des équipements particuliers sont données en Annexe A, et les circuits d'essai sont indiqués en Figure 1. Cette deuxième édition de la CEI 61000-3-3 annule et remplace la première édition parue en 1994, l'amendement 1 (2001) et l'amendement 2 (2005). Cette édition constitue une édition révisée. NEW! La CEI 61000-3-3:2008 est également disponible sous forme de IEC Standards+ 61000-3-3:2008 qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.

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
