Method for marking bundles of power lines for diagnosis by reflectometry and corresponding kit

Résumé

Disclosed is a method for diagnosis by reflectometry of a bundle of power lines including an input point and a plurality of branches, including the following steps: inserting (S50) electric markers having different frequency characteristics onto the branches of the bundle; injecting (S52) a test signal into the bundle from the input point; receiving (S54) a set of reflected signals produced by reflections of the test signal in the branches; analyzing all the reflected signals by identifying the markers and by assigning (S56) each reflected signal to one of the branches according to the frequency characteristic of the marker inserted onto the branch; and identifying the presence/absence of a defect in the branch by comparing (S58) the reflected signal assigned to the branch with a reflected signal model obtained by modelling the reflection of the test signal in the branch in the absence of any defect in the branch.
