| description | System for monitoring high-tension cables (1) in air stretches as well as a use of the same. The system comprises at least one optic fibre (3) fastened to the high-tension cable (1), said optic fibre comprising at least one Bragg grating (4) with known reflection characteristics, a light source (6) for emitting light within a known range of wavelengths into the optic fibre, and measuring devices (7) for detection of light reflected from the Bragg gratings (4) in the fibre (3) and for recognizing light reflected from each Bragg grating (4) based on their known reflection characteristics.
L'invention porte sur un système de surveillance de câbles (1) haute tension, aériens, ainsi que sur leur utilisation. Ce système comprend au moins une fibre optique (3) fixée au câble haute tension (1) et constituée d'au moins un réseau de Bragg (4) présentant des caractéristiques de réflexion connues, une source lumineuse (6) émettant de la lumière dans la fibre optique dans une plage connue de longueurs d'onde, et des dispositifs de mesure (7) détectant la lumière renvoyée dans la fibre (3) par le réseau de Bragg (4) et identifiant la lumière renvoyée par chaque réseau de Bragg (4) sur la base de leurs caractéristiques de réflexion connues. |
