(Main)

Electromagnetic compatibility (EMC) - Part 1-4: General - Historical rationale for the limitation of power-frequency conducted harmonic current emissions from equipment, in the frequency range up to 2 kHz

Electromagnetic compatibility (EMC) - Part 1-4: General - Historical rationale for the limitation of power-frequency conducted harmonic current emissions from equipment, in the frequency range up to 2 kHz

IEC TR 61000-1-4:2022 is available as IEC TR 61000-1-4:2022 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC TR 61000-1-4:2022 which is a technical report, reviews the sources and effects of power frequency conducted harmonic current emissions in the frequency range up to 2 kHz on the public electricity supply, and gives an account of the reasoning and calculations leading to the existing emission limits for equipment in the editions of IEC 61000-3-2, up to and including the fifth edition (2018) with Amendment 1 (2020), and in the second edition of IEC 61000-3-12. The history is traced from the first supra-national standard on low-frequency conducted emissions into the public electricity supply, EN 50006:1975 and its evolution through IEC (60)555-2 to IEC 61000-3-2, IEC TR 61000-3-4 and IEC 61000-3-12. To give a full picture of the history, that of the standard for the measuring instrument IEC 61000-4-7 is mentioned as well. NOTE All IEC standards were renumbered starting from 60000 from 1998-01-01. To indicate the references of standards withdrawn before, or not reprinted after, that date, the “60x” prefix is here enclosed in parentheses. Hence “IEC (60)555-2”. Some concepts in this document apply to all low voltage AC systems, but the numerical values apply specifically to the European 230 V/400 V 50 Hz system. This second edition cancels and replaces the first edition published in 2005. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- relation between compatibility levels, emission limits and immunity requirements clarified;
- sharing of emission levels between LV, MV and HV clarified;
- new historical information added.

IEC TR 61000-1-8:2019(Main)
Electromagnetic compatibility - Part 1-8: Phase angles of harmonic current emissions and voltages in the public supply networks - Future expectations

IEC TR 61000-1-8:2019, which is a technical report, provides information about the current conditions, and project future developments, of prevailing phase angles, predominantly for the 3rd and 5th harmonic currents, on public supply networks. This objective is accomplished by monitoring a number of networks, and efforts to forecast the effects of changes in technologies. This document presents information to guide the discussion about the effectiveness of potential mitigation techniques and the generalisation of effects of the prevailing angle positions of selected current harmonics. This document mainly deals with the phase angles of the 3rd and 5th harmonic currents, but also contains information about other harmonics.
Keywords: 3rd and 5th harmonic currents, phase angles

Electromagnetic compatibility (EMC) - Part 3-2: Limits - Limits for harmonic current emissions (equipment input current ≤16 A per phase)

IEC 61000-3-2:2018 est disponible sous forme de IEC 61000-3-2:2018 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.  L’IEC 61000-3-2:2018 traite de la limitation des courants harmoniques injectés dans le réseau public d’alimentation. Elle définit les limites des harmoniques du courant d’entrée qui peuvent être produits par les matériels soumis à l’essai dans des conditions spécifiées. La présente partie de l’IEC 61000 est applicable aux appareils électriques et électroniques ayant un courant d’entrée assigné dont la valeur est inférieure ou égale à 16 A par phase et qui sont destinés à être raccordés à des réseaux publics de distribution à basse tension. Le matériel de soudage à l'arc qui n’est pas du matériel professionnel, dont le courant d’entrée assigné est inférieur ou égal à 16 A par phase, relève du présent document. Le matériel de soudage à l'arc destiné à un usage professionnel, tel que spécifié dans l’IEC 60974-1, est exclu du domaine d'application du présent document et peut être sujet à des restrictions d'installation comme indiqué dans l'IEC 61000-3-12. Les essais effectués conformément au présent document sont des essais de type. Les limites applicables aux réseaux dont la tension nominale est strictement inférieure à 220 V (entre phase et neutre) n'ont pas encore été envisagées. Cette cinquième édition annule et remplace la quatrième édition parue en 2014. Cette édition constitute une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) une mise à jour des limites d’émission pour les appareils d'éclairage ayant une puissance assignée ≤ 25 W afin de tenir compte des nouveaux types d’appareils d'éclairage; b) l’ajout d'un seuil de 5 W en dessous duquel aucune limite d’émission ne s’applique à l’ensemble des appareils d'éclairage; c) la modification des exigences qui s’appliquent aux variateurs de lumière lorsqu'ils font fonctionner des lampes qui ne sont pas à incandescence; d) l’ajout de conditions d'essai applicables aux dispositifs de commande d'éclairage par transmission numérique côté charge; e) la suppression de l'emploi de lampes de référence et de ballasts de référence pour les essais des appareils d'éclairage; f) la simplification et la clarification de la terminologie employée pour les appareils d'éclairage; g) la classification en classe A des luminaires professionnels pour l'éclairage des scènes de théâtre et pour les studios; h) une clarification de la classification des appareils d'éclairage de secours; i) une clarification pour les appareils d'éclairage comportant un module de commande ayant une puissance active d’entrée ≤ 2 W; j) une mise à jour des conditions d’essai des récepteurs de télévision; k) une mise à jour des conditions d’essai des tables de cuisson à induction, tenant compte également des autres types d’appareils de cuisson; l) en cohérence avec l’IEC 61000-3-12, une modification du domaine d’application de l’IEC 61000-3-2, qui couvrait les appareils ayant un courant d’entrée ≤ 16 A, et qui couvre maintenant les appareils ayant un courant d’entrée assigné ≤ 16 A.

Electromagnetic compatibility (EMC) - Part 3-2: Limits - Limits for harmonic current emissions (equipment input current ≤ 16 A per phase)

IEC 61000-3-2:2014 deals with the limitation of harmonic currents injected into the public supply system. It specifies limits of harmonic components of the input current which may be produced by equipment tested under specified conditions. It is applicable to electrical and electronic equipment having an input current up to and including 16 A per phase, and intended to be connected to public low voltage distribution systems. Arc welding equipment which is not professional equipment, with input current up to and including 16 A per phase, is included in this standard. Arc welding equipment intended for professional use, as specified in IEC 60974-1, is excluded from this standard and may be subject to installation restrictions as indicated in IEC/TR 61000-3-4 or IEC 61000-3-12. The tests according to this standard are type tests. Test conditions for particular equipment are given in Annex C. For systems with nominal voltages less than 220 V (line-to-neutral), the limits have not yet been considered.
