Abstract

L'invention concerne un testeur de rigidité diélectrique à sec de la gaine isolante d'un câble électrique, comportant une source de haute tension alternative, appliquée entre l'âme du câble reliée à la masse et la surface extérieure de la gaine. Le contact électrique avec la gaine est assuré uniquement par un tube entourant le câble et rempli d'une atmosphère ionisée, la tension nécessaire à l'ionisation étant fournie par un générateur indépendant du circuit de mesure.
