Abstract
L’invention concerne un procédé de détection et localisation instantanées des défauts dans les tuyaux de distribution caractérisé en ce qu’il est basé sur : • un circuit électrique incorporé dans la gaine du tuyau comprenant des résistances électriques identiques en parallèle. • un générateur qui applique une tension au circuit électrique au moment du contrôle • une mesure du courant qui traverse le circuit et déduction de la résistance équivalente. Cette invention fondée sur une approche de contrôle préventif permet d’anticiper les dégâts en milieu résidentiel et industriel. L'invention concerne en outre un dispositif pour la mise en œuvre dudit procédé.
