Abstract

L'invention concerne un procédé et un dispositif de localisation de défauts et de repérage d'une canalisation. Un générateur 10 émet deux fréquences, 400 et 1000 Hz, qu'on injecte à chacune des extrémités 3, 4 d'une ligne 1 pour y localiser un défaut 2. Une canne 24 comporte deux détecteurs 21, 22, à large bande passante, un système amplificateur 28 et un casque d'écoute 27. L'invention s'applique à la localisation des défauts et au repérage des canalisations.
