A system for measuring a voltage differential in a current-carrying pipe (102)using a propulsion vehicle (108) for conveying the system inside the pipe (102), the system comprising a first contact (116) for maintaining electrical contact with the pipe (102) as the vehicle (108) moves through the pipe (102), a second contact (118) positioned in a spaced apart relationship from said first contact (116) for maintaining electrical contact with the pipe (102) as the vehicle (108) moves through the pipe (102), and a voltage reading device (212) connected to said first contact (116) and said second contact (116) for measuring the voltage between said first contact (116) and said second contact (118) as the vehicle moves through the pipe.

L'invention porte sur un système de mesure d'un différentiel de tension dans une canalisation sous tension (102), au moyen d'un véhicule à propulsion (108) afin d'acheminer le système à l'intérieur de la canalisation (102), ce système comprenant un premier contact (116) permettant de maintenir un contact électrique avec la canalisation (102) pendant que le véhicule (108) se déplace à travers la canalisation (102), un second contact (118) positionné dans une relation espacée dudit premier contact (116) afin de maintenir un contact électrique avec la canalisation (102) pendant que le véhicule (118) se déplace à travers le conduit (102), et un dispositif de lecture de tension (212) relié au premier contact (116) et audit second contact (118) afin de mesurer la tension entre le premier contact (116) et le second contact (118) pendant que le véhicule se déplace à travers la canalisation.
