Abstract
L'invention concerne un procédé de mesure directe du taux d'humidité dans un transformateur rempli d'huile (100) qui consiste à utiliser une fibre optique (130) qui comporte un capteur à réseau (140), tel qu'un réseau de Bragg pour fibre, délimité dans la fibre optique. Les divers conducteurs (enroulements) dans le transformateur sont isolés à l'aide d'un isolant tel que du papier et de l'huile isolante est remplie à l'intérieur du transformateur. L'humidité dans le transformateur est absorbée par le papier (120) qui entoure les enroulements (110). Un taux d'humidité en un emplacement spécifique peut être mesuré en plaçant la fibre optique avec le capteur à réseau directement au niveau de l'emplacement spécifique à mesurer. Un paramètre physique du papier qui a absorbé l'humidité varie au cours du temps, provoquant un changement dans le capteur à réseau de la fibre optique qui modifie la réponse spectrale de signaux optiques qui sont réfléchis par le capteur à réseau. Le procédé fournit un procédé précis de mesure de l'humidité à l'intérieur du transformateur au niveau de l'emplacement spécifique.
