1 ожидаемый ток включения (для полюса коммутационного аппарата)
ожидаемый ток включения (для полюса коммутационного аппарата) Ожидаемый ток, возникающий в установленных условиях. Примечание. Установленные условия могут касаться способа возникновения, например при применении идеального коммутационного аппарата, или момента возникновения, например обусловливающего максимальный ожидаемый пиковый ток в цепи переменного тока, или максимальной скорости нарастания.
Условия уточняются в стандартах на соответствующие аппараты.

prospective making current (for a pole of a switching device) the prospective current when initiated under specified conditions
NOTE The specified conditions may relate to the method of initiation, e.g. by an ideal switching device, or to the instant of initiation, e.g. leading to the maximum prospective peak current in an a.c. circuit, or to the highest rate of rise. The specification of these conditions is found in the relevant publications.

courant établi présumé (d’un appareil de connexion) courant présumé lorsqu’il est établi dans des conditions spécifiées
NOTE Les conditions spécifiées peuvent se rapporter à la méthode d’établissement, par exemple par un appareil de connexion idéal, ou à l’instant d’établissement, par exemple conduisant à la valeur maximale de crête ou à la vitesse maximale d’accroissement. La spécification de ces conditions est donnée dans les publications particulières.

2 номинальное напряжение ОПН
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).
