Abstract

L'invention concerne un procédé permettant de déterminer l'intensité d'un courant exceptionnellement fort dans un conducteur (4), lequel procédé consiste à mesurer l'angle de rotation d'une lumière polarisée (6, 7, 8) émanant d'une source lumineuse (1, 2) dans un champ magnétique créé par le courant, à l'aide d'un détecteur (3) à fibre de verre composé de verre fluoré caractérisé par une faible constante de Verdet et un coefficient photoélastique ne dépassant pas 0,25 (nm/cm)/(kg/cm?2¿) environ.
