The invention relates to an arrangement for measuring an electrical variable on a high voltage line. An electrically conductive hollow body that can be connected to an earth potential is connected to a hollow insulating body in such a way as to form a cavity through which an electrical conductor is guided, inside. A section of the insulating body at the hollow body-side end is surrounded on the outside by a shielding body. An electrical transformer surrounds the hollow body outside of the cavity. The arrangement is explosion- proof and can be produced comparatively economically.
L'invention concerne un dispositif permettant de mesurer une grandeur électrique d'une ligne haute tension. Un corps creux électroconducteur et connecté au potentiel du sol est assemblé à un corps isolant creux de telle façon qu'il y ait, à l'intérieur, une cavité par laquelle passe la ligne électrique. A cette occasion, une section du corps isolant est recouverte, à l'extrémité côté corps creux et à l'extérieur, d'un corps de blindage. Un transformateur électrique entoure le corps creux en dehors de la cavité. Le dispositif est à l'épreuve de l'explosion et sa fabrication est comparativement économique.
