3 rated voltage of an arrester
номинальное напряжение
Uн
Действующее значение напряжения промышленной частоты, которое ограничитель может выдерживать в течение 10 с в процессе рабочих испытаний. Номинальное напряжение должно быть не менее 1,25 наибольшего длительно допустимого рабочего напряжения.

rated voltage of an arrester
Ur
maximum permissible r.m.s. value of power-frequency voltage between its terminals at which it is designed to operate correctly under temporary overvoltage conditions as established in the operating duty tests
NOTE 1 The rated voltage is used as a reference parameter for the specification of operating characteristics.
NOTE 2 The rated voltage as defined in this standard is the 10 s power-frequency voltage used in the operating duty test after high-current or long-duration impulses. Tests used to establish the voltage rating in IEC 60099-1, as well as some national standards, involve the application of repetitive impulses at nominal current with power-frequency voltage applied. Attention is drawn to the fact that these two methods used to established rating do not necessarily produce equivalent values (a resolution to this discrepancy is under consideration).

tension assignée d'un parafoudre
Ur
valeur maximale de la tension efficace à fréquence industrielle admissible entre ses bornes pour laquelle le parafoudre est prévu pour fonctionner correctement dans des conditions de surtension temporaires comme il est défini dans les essais de fonctionnement
NOTE 1 La tension assignée est utilisée comme paramètre de référence pour la spécification des caractéristiques de fonctionnement.
NOTE 2 La tension assignée comme définie dans la présente norme est la tension à fréquence industrielle de 10 s, utilisée pour vérifier la stabilité après application des chocs de courant de grande amplitude ou de longue durée lors de l'essai de fonctionnement. Les essais utilisés pour définir la tension assignée dans la CEI 60099-1, ainsi que dans certaines normes nationales, impliquent l'application de chocs répétés au courant nominal pendant que la tension à fréquence industrielle est appliquée. On attire l'attention sur le fait que ces deux méthodes utilisées pour définir les valeurs assignées ne produisent pas nécessairement des valeurs équivalentes (une résolution de cette différence est à l'étude).
