A high voltage measuring device for measuring the voltage between two spaced- apart points has a poled optical fibre (7) extended between said points and subject to an electric field associated with said voltage. A control unit (15) has light emitting means, which transmits light into the fibre, and detecting means for receiving light transmitted through the fibre and for generating a signal (Sout) corresponding to a change in refractive index of the fibre caused by said electric field.
Dispositif de mesure de haute tension servant à mesurer la tension entre deux points espacés, qui est doté d'une fibre optique polarisée (7) reliant les deux points que l'on soumet à un champ électrique associé à ladite tension. Une unité de commande (15) est pourvue d'un émetteur de lumière qui transmet de la lumière à la fibre, et d'un détecteur servant à réceptionner la lumière acheminée à travers la fibre et à générer un signal (S¿sortie?) correspondant au changement de l'indice de réfraction de la fibre provoqué par ledit champ électrique.
