IEC 61000-4-34-ed.1.0

Annotation of standard text IEC 61000-4-34-ed.1.0 :

This part of IEC 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 exceeding 16 A per phase. It covers equipment installed in residential areas as well as industrial machinery, specifically voltage dips and short interruptions for equipment connected to either 50 Hz or 60 Hz a.c. networks, including 1-phase and 3-phase mains. 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. The test method documented in this part of IEC 61000 describes a consistent method to assess the immunity of equipment or a system against a defined phenomenon. It has the status of a Basic EMC Publication in accordance with IEC Guide 107. La presente partie de la CEI 61000 definit les methodes dessai dimmunite ainsi que la gamme des niveaux dessais preferes pour les materiels electriques et electroniques connectes a des reseaux dalimentation basse tension pour les creux de tension, les coupures breves et les variations de tension. La presente norme sapplique aux materiels electriques et electroniques dont le courant nominal dentree depasse 16 A par phase. Elle sapplique aux materiels installes dans des environnements residentiels de meme quaux materiels industriels, pour laspect creux de tension et coupures breves des equipements, monophases et triphases, relies a des reseaux electriques alternatif de 50 Hz ou 60 Hz. Le but de cette norme est detablir une reference commune pour levaluation de limmunite fonctionnelle des materiels electriques et electroniques soumis a des creux de tension, a des coupures breves et a des variations de tension. La methode dessai decrite dans la presente partie de la CEI 61000 detaille une methode sans faille pour estimer limmunite dun materiel ou dun systeme a un phenomene predefini. Elle a le statut de publication fondamentale en CEM conformement au Guide 107 de la CEI.
