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.The invention relates to a method for instantaneous detection and localization of faults in distribution pipes characterized in that it is based on: • an electrical circuit incorporated in the sheath of the pipe comprising identical electrical resistors in parallel. • a generator which applies a voltage to the electric circuit at the time of the test • a measurement of the current which crosses the circuit and deduction of the equivalent resistance. This invention, based on a preventive control approach, makes it possible to anticipate damage in residential and industrial environments. The invention further relates to a device for implementing said method.
