| Zusammenfassung: | The invention relates to a device (1) for measuring a voltage comprising first and second conducting terminals (2, 4) between which the voltage is measured; an isolator (6) separating the first and second terminals; an optical sensor (16) measuring the electric field at a location between the first and second terminals, the optical sensor comprising an isotropic electrooptical crystal (30) between the first and second terminals; and a detector (18) determining the voltage on the basis of the electric field measured.
L'invention concerne un dispositif (1) de mesure d'une tension comprenant des première et seconde bornes conductrices (2, 4) entre lesquelles la tension est mesurée; un isolateur (6) séparant les première et seconde bornes; un capteur optique (16) mesurant le champ électrique en un emplacement entre les première et seconde bornes, le capteur optique comprenant un cristal électro-optique (30) isotrope entre les première et seconde bornes; et un détecteur (18) déterminant la tension à partir du champ électrique mesuré. |
