ABSTRACT:
A method of detecting the presence of an electric cable, the electric cable including conductive armoring and a conductive core that is electrically insulated from the armoring. In the method, the armoring is connected to ground, and a current pulse is emitted over the armoring by way of a current injector device connected to ground so that the return of the pulse to the injector device takes place via ground. The presence of the electric cable is detected in the proximity of a reception point by detecting, at the point, a signal that is representative of the pulse, by way of a detector.
