Abstract
A system for monitoring the state of a cable, includes a plurality of reflectometry devices able to inject a test signal at a point of injection into the cable and to measure a signal having propagated back through the cable to the point of injection into the cable, the reflectometry devices being intended to be positioned along the cable so as to divide the cable into successive segments, the system comprising a control unit that is able to communicate with the reflectometry devices and that is configured so as to carry out at least one reflectometry test consisting in injecting a test signal into the cable by means of a first reflectometry device and measuring the test signal, by means of the first reflectometry device, after it has propagated through the cable and been reflected from an impedance discontinuity, the system further comprising a post-processing unit able to communicate with the reflectometry devices and configured to analyze the measurement of the test signal with a view to detecting an amplitude peak corresponding to a fault.
