Abstract

Procédé et installation pour la mesure à un poste de l'intensité d'un courant électrique circulant dans un circuit distant dudit poste et susceptible d'être à un potentiel très différent de ce dernier. On adjoint audit circuit un tube à décharge lumineuse et un circuit associé dont les caractéristiques sont choisies pour que le tube fournisse des impulsions lumineuses par relaxation à partir du courant à mesurer, un conducteur de lumière étant interposé entre ledit tube et une photodiode ou analogue que comporte le poste de mesure. Application à la mesure du courant d'ionisation résultant d'un effet de pointe ou effet corona.
