Abstract: A method for detecting soft faults in a transmission line includes the following steps: acquiring a measurement, called time-domain reflectogram, of a signal characteristic of the reflection of a reference signal previously injected into the line, determining the difference between the time-domain reflectogram and a time-domain reflectogram measured previously for the same line or an identical line of similar characteristics, in order to obtain a corrected time-domain reflectogram, applying a plurality of independent transformations to the corrected time-domain reflectogram in order to obtain a plurality of independent transformed reflectograms, converting the transformed reflectograms into a plurality of mutually independent probabilities of occurrence of a fault, applying a data merging method to the probabilities of occurrence of a fault to deduce therefrom a unified value of the probability of occurrence of a fault.

Abstract: A method for detecting soft faults in a transmission line includes the steps of: acquiring a time-domain reflectogram, calculating the integral of the time-domain reflectogram, selecting, in the integral, three samples P1, P2, P3, calculating a first distance equal to the difference in absolute value between the value of the second sample P2 and the value of the first sample P1 or of the third sample P3, calculating a second distance equal to the difference in absolute value between the value of the first sample P1 and of the third sample P3, performing a first comparison of the first distance to the second distance weighted by a weighting coefficient ?, deducing from the result of the first comparison information on the existence of a soft fault.
