2 классификационное напряжение ОПН
классификационное напряжение ОПН
Uкл
Максимальное (амплитудное) значение напряжения промышленной частоты, деленное на √2, которое должно быть приложено к ОПН для получения классификационного тока. Классификационное напряжение многоэлементного ОПН определяется как сумма классификационных напряжений отдельных элементов.
[ ГОСТ Р 52725-2007]EN
reference voltage of an arrester, Uref
peak value of power-frequency voltage divided by √2 which is applied to the arrester to obtain the reference current
NOTE 1 The reference voltage of a multi-unit arrester is the sum of the reference voltages of the individual units.
NOTE 2 Measurement of the reference voltage is necessary for the selection of a correct test sample in the operating duty test.

tension de référence d'un parafoudre, Uref
valeur de crête divisée par √2 de la tension à fréquence industrielle qui est appliquée aux bornes du parafoudre pour que celui-ci soit parcouru par le courant de référence.
NOTE 1 La tension de référence d'un parafoudre à plusieurs éléments est la somme des tensions de référence des éléments séparés.
NOTE 2 La mesure de la tension de référence est nécessaire au choix d'un échantillon d'essai convenable dans l'essai de fonctionnement.
