Abstract
Une fuite dans une membrane au sommet d'un tablier de toit horizontal se détecte en appliquant des fils conducteurs sur la membrane sous l'agrégat dans un motif de grille. Un circuit de mesure et de commutation génère une tension ayant un pôle positif fixé au tablier de toit et un pôle négatif fixé aux fils. Le circuit possède un relais pour chaque fil qui peut être commuté entre un système de capteur de courant et le potentiel négatif. Le système de capteur est disposé pour identifier au niveau de chaque fil tour à tour le flux de courant du tablier de toit à travers toute fuite dans la membrane se ressentant sur le fil. Un microprocesseur effectue les relais tour à tour pour connecter tous les autres fils sur le pôle négatif agissant comme un bouclier pendant que chaque fil est sondé. partir de la sortie de la grille, les fluctuations du courant dans les directions x et y sont analysées pour localiser la fuite dans la membrane.
