Abstract

A method for automatically measuring physical characteristics of a cable, comprises at least the following steps: positioning on said cable of means for creating an artificial singularity; the injection, at a point of said cable, of an electrical test signal; acquisition of said signal reflected on the singularities that said cable includes so as to produce a first reflectogram; measurement, on said reflectogram, of the temporal position Δt of the peak of the signal derived from its reflection on said artificial singularity; determination of the propagation velocity vp=2x/Δt of the signal in said cable from the temporal position Δt and from the position x of said means for creating an artificial singularity on the cable.
