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 β, deducing from the result of the first comparison information on the existence of a soft fault.
