A method of determining the magnitude of an exceptionally large current in a conductor (4) which comprises measuring the angle of rotation of polarized light (6, 7, 8) from a light source (1, 2) in a magnetic field created by the current with a glass fiber (3) sensor composed of a fluoride glass having a low Verdet constant and a photoelastic coefficient not over about 0.25 (nm/cm)/(kg/cm2).
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.
