классификационный ток ОПН
Iкл

reference current of an arrester
peak value (the higher peak value of the two polarities if the current is asymmetrical) of the resistive component of a power-frequency current used to determine the reference voltage of the arrester
NOTE 1 The reference current will be high enough to make the effects of stray capacitances at the measured reference voltage of the arrester units (with designed grading system) negligible and is to be specified by the manufacturer.
NOTE 2 Depending on the nominal discharge current and/or line discharge class of the arrester, the reference current will be typically in the range of 0,05 mA to 1,0 mA per square centimetre of disc area for single column arresters.

courant de référence d'un parafoudre
valeur de crête (la plus grande des deux polarités si le courant est dissymétrique) de la composante résistive du courant à fréquence industrielle utilisée pour déterminer la tension de référence d'un parafoudre.
NOTE 1 Il convient que le courant de référence soit suffisamment élevé pour rendre négligeables les effets des capacités parasites aux tensions de référence mesurées sur les éléments de parafoudre (avec leur système de répartition) et qu’il soit spécifié par le constructeur.
NOTE 2 Fonction du courant de décharge nominal et/ou de la classe de décharge de ligne du parafoudre, il convient que le courant de référence soit typiquement dans la gamme de 0,05 mA à 1,0 mA par centimètre carré de surface de disque pour les parafoudres à colonne unique
