Electromagnetic compatibility (EMC) - Part 2-4: Environment - Compatibility levels in power distribution systems in industrial locations for low-frequency conducted disturbances

IEC 61000-2-4:2024 is available as IEC 61000-2-4:2024 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 61000-2-4:2024 is related to conducted disturbances in the frequency range from 0 kHz to 150 kHz. It gives compatibility levels in differential mode (L-L and L-N) for industrial locations, with a nominal voltage up to 35 kV and a nominal frequency of 50 Hz or 60 Hz.
NOTE 1 Industrial locations are defined in 3.1.8.
Power distribution systems on ships, aircraft, offshore platforms and railways are not included.
NOTE 2 See also Annex E. The compatibility levels specified in this document apply at the in-plant point of coupling (IPC). The level of the low-frequency disturbances at the terminals of equipment receiving its supply from the IPC is generally assumed to be similar to the disturbance level at the IPC itself. However, in some situations this is not the case, particularly when a long feeder is dedicated to the supply of a particular load, or when a disturbance is generated or amplified within the installation of which the equipment forms a part.
Compatibility levels are specified for the types of low-frequency electromagnetic disturbances expected at any in-plant point of coupling (IPC) within industrial locations, for guidance in the definition of:
a) limits for disturbance emissions in industrial power distribution systems (including the planning levels defined in 3.1.5);
NOTE 3 A very wide range of conditions is possible in the electromagnetic environments of industrial networks. These are approximated in this document by the three classes described in Clause 4. However, it is the responsibility of the operator of such a network to take account of the particular electromagnetic and economic conditions, including equipment characteristics, in setting the above-mentioned limits.
b) immunity levels for the equipment within these systems.
The disturbance phenomena considered are:
- voltage deviations;
- voltage dips and short interruptions;
- voltage imbalance;
- power-frequency variations;
- harmonics up to order 40;
- interharmonics up to the 40th harmonic;
- voltage components above the 40th harmonic up to 150 kHz;
- DC component;
- transient overvoltages.
The compatibility levels are given for different classes of environment determined by the characteristics of the supply network and loads.
NOTE 4 Compatibility levels at the point of common coupling (PCC) on public networks are specified in IEC 61000‑2‑2 for low-voltage networks and IEC 61000‑2‑12 for medium-voltage networks. IEC TR 61000‑3‑6 and IEC TR 61000‑3‑7 describe the approach of power distribution system operators to the limitation of emissions from installations and large loads.
This third edition cancels and replaces the second edition published in 2002. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) introduction of new classes 2a, 2b and 2L (former class 2);
b) modification of existing compatibility levels for class 3;
c) addition of compatibility levels in the frequency range 2 kHz to 150 kHz;
d) addition of compatibility levels using a new quantity: partial weighted harmonic distortion (PWHD).

Elektromagnetische Verträglichkeit (EMV) - Teil 2-4: Umgebungsbedingungen - Verträglichkeitspegel für niederfrequente leitungsgeführte Störgrößen in Industrieanlagen

Compatibilité électromagnétique (CEM) - Partie 2-4: Environnement - Niveaux de compatibilité dans les installations industrielles pour les perturbations conduites à basse fréquence

IEC 61000-2-4:2024 est disponible sous forme de IEC 61000-2-4:2024 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.

L'IEC 61000-2-4:2024 traite des perturbations conduites dans la plage de fréquences de 0 kHz à 150 kHz. Elle fournit les niveaux de compatibilité en mode différentiel (L-L et L-N) pour les sites industriels, avec une tension nominale jusqu'à 35 kV et une fréquence nominale de 50 Hz ou 60 Hz.
NOTE 1 Les sites industriels sont définis au 3.1.8.
Les réseaux de distribution d'électricité sur les navires, les aéronefs, les plateformes en mer et les réseaux ferroviaires sont exclus.
NOTE 2 Voir aussi l'Annexe E. Les niveaux de compatibilité spécifiés dans le présent document s'appliquent au point de couplage interne à l'installation (IPC). Le niveau des perturbations à basse fréquence aux bornes des équipements alimentés par l'IPC est par hypothèse généralement similaire au niveau de perturbation à l'emplacement de l'IPC. Toutefois, cela n'est pas le cas dans certaines situations, particulièrement avec un départ destiné à l'alimentation d'une charge spécifique par une ligne longue ou lorsqu'une perturbation est générée ou amplifiée dans l'installation dont les équipements font partie.
Les niveaux de compatibilité sont spécifiés pour les différents types de perturbations électromagnétiques à basse fréquence qui sont attendues en tout point de couplage interne à l'installation (IPC) dans des sites industriels, afin de fournir des recommandations pour définir:
a) les limites relatives aux émissions perturbatrices sur les réseaux de distribution d'électricité industriels (y compris les niveaux de planification définis au 3.1.5);
NOTE 3 Les conditions présentes dans les environnements électromagnétiques des réseaux industriels peuvent être très variées. Ces conditions sont représentées dans le présent document par les trois classes décrites à l'Article 4. Néanmoins, il est de la responsabilité de l'exploitant d'un tel réseau de prendre en compte les conditions électromagnétiques et économiques particulières, notamment les caractéristiques des équipements, pour établir les limites susmentionnées.
b) les niveaux d'immunité des équipements présents dans ces systèmes.
Les phénomènes perturbateurs suivants sont pris en compte:
- les écarts de tension;
- les creux de tension et les coupures brèves;
- les déséquilibres de tension;
- les variations de la fréquence du réseau d'alimentation;
- les harmoniques jusqu'au rang 40 inclus;
- les interharmoniques jusqu'au rang harmonique 40;
- les composantes de tension au-dessus du rang harmonique 40 jusqu'à 150 kHz;
- la composante continue;
- les surtensions transitoires.
Les niveaux de compatibilité sont donnés pour différentes classes d'environnement, qui sont déterminées par les caractéristiques du réseau d'alimentation et des charges associées.
NOTE 4 Les niveaux de compatibilité au point de couplage commun (PCC) sur les réseaux publics sont spécifiés dans l'IEC 61000‑2‑2 pour les réseaux basse tension et dans l'IEC 61000‑2‑12 pour les réseaux moyenne tension. L'IEC TR 61000‑3‑6 et l'IEC TR 61000‑3‑7 décrivent l'approche des exploitants de réseaux de distribut
