      Scope and object


      This part of IEC 61000 is a basic EMC (electromagnetic compatibility) publication. It considers immunity tests for electric and/or electronic equipment (apparatus and system) in its electromagnetic environment. Only conducted phenomena are considered, including immunity tests for equipment connected to public and industrial networks.


      The object of this standard is to establish a reference for evaluating the immunity of electrical and electronic equipment when subjected to unbalanced power supply voltage.


      This standard applies to 50 Hz/60 Hz three-phase powered electrical and/or electronic equipment with rated line current up to 16 A per phase.


      This standard does not apply to equipment with three-phase plus neutral connection if that equipment operates as a group of single-phase loads connected between phase and neutral.


      This standard does not apply to electrical and/or electronic equipment connected to a.c. 400 Hz distribution networks.


      This standard does not include tests for the zero-sequence unbalance factor.


      The immunity test levels required for a specific electromagnetic environment together with performance criteria are indicated in the product, product family or generic standards as applicable. This immunity test should be included in product, product family or generic standards when equipment is likely to show reduced performance or function when exposed to a supply voltage with voltage unbalance.


      The verification of the reliability of electrical components (capacitors, motors, etc.) and long- term effects (greater than a few minutes) is not considered in this standard.

      Domaine d'application et objet


      La présente partie de la CEI 61000 est une publication fondamentale en CEM (Compatibilité électromagnétique). Elle porte sur les essais d'immunité des équipements électriques et/ou électroniques (appareils et systèmes) dans leur environnement électromagnétique. Seuls les phénomènes conduits sont pris en compte, et notamment les essais d'immunité des équipements reliés aux réseaux publics et industriels.


      La présente norme a pour objet d'établir une référence pour évaluer l'immunité des équipements électriques et électroniques soumis à des déséquilibres de tension.


      Cette norme s'applique aux équipements triphasés électriques et/ou électroniques 50 Hz/ 60 Hz, absorbant un courant nominal inférieur ou égal à 16 A par phase.


      Cette norme ne s'applique pas aux équipements triphasés ayant un neutre s'ils fonctionnent comme un groupe de charges monophasées branchées entre phase et neutre.


      Cette norme ne s'applique pas aux équipements électriques et/ou électroniques raccordés aux réseaux de distribution en courant alternatif à 400 Hz.


      Les essais de cette norme ne comprennent pas les essais relatifs au facteur de déséquilibre homopolaire.


      Les niveaux d'immunité exigés pour un environnement électromagnétique particulier, ainsi que les critères de performances, sont indiqués dans les normes de produit, de famille de produits ou dans les normes génériques selon le cas. Cet essai d'immunité ne devrait être inclus dans les normes de produit, de famille de produits ou dans des normes génériques que si le matériel est susceptible de présenter une aptitude à la fonction ou un fonctionnement réduit lorsqu'il est soumis à une alimentation en tension comportant un déséquilibre.


      La vérification de la fiabilité des matériels électriques (condensateurs, moteurs, etc.) et les effets de longue durée (plus de quelques minutes) ne sont pas traités dans cette norme.
