Abstract

La présente invention concerne un dispositif de mesure de la rupture d'un diélectrique en présence d'une tension élevée, et permettant de mesurer par exemple la production d'ozone dans un générateur d'ozone fonctionnant suivant le principe de décharge corona. Le procédé consiste à détecter par effet capacitif les impulsions de décharge corona dans un générateur d'ozone. Un filtre permet d'éliminer les basses fréquences du signal détecté. Le bruit électrique issu des circuits du transformateur est isolé par un coupleur optique dont l'alimentation électrique en courant continu est isolée. Après filtrage, le signal est amplifié et transformé en tension à courant continu. Après étalonnage de la quantité d'ozone effectivement produite, la sortie de courant continu, qu'il est possible de rapporter directement à la quantité d'ozone produite dans le générateur, peut servir pour afficher et/ou réguler la production d'ozone.
