Electromagnetic compatibility (EMC) - Part 4-24: Testing and measurement techniques - Test methods for protective devices for HEMP conducted disturbance
IEC 61000-4-24:2015 deals with methods for testing protective devices for HEMP conducted disturbance. It includes two-terminal elements, such as gas discharge tubes, varistors, and two-port SPDs, such as HEMP combination filters. It covers testing of voltage breakdown and voltage-limiting characteristics but also methods to measure the residual voltage and/or the residual current, peak rate of rise and root action for the case of very fast changes of voltage and current as a function of time. It has the status of a basic EMC publication in accordance with IEC Guide 107. This second edition cancels and replaces the first edition published in 1997. This edition constitutes a technical revision.
Compatibilité électromagnétique (CEM) - Partie 4-24: Techniques d'essai et de mesure - Méthodes d'essai pour les dispositifs de protection pour perturbations conduites IEMN-HA
L'IEC 61000-4-24:2015 définit les méthodes d'essai concernant les dispositifs de protection IEMN-HA contre les perturbations conduites. Elle inclut les éléments à deux bornes, tels que les tubes à décharge, varistances et les parafoudres à deux accès, tels que les filtres combinés IEMN-HA. Elle couvre les essais de caractéristiques de tension de claquage et de limitation de la tension résiduelle incluant les méthodes de mesure de tension résiduelle et/ou de courant résiduel, de la valeur de crête du temps de montée et de l'action racine dans le cas de variations très rapides de tension et de courant en fonction du temps. Elle a le statut de publication CEM de base conformément au Guide 107 de l'IEC. Cette deuxième édition annule et remplace la première édition parue en 1997. Cette édition constitue une révision technique.
