A method for detecting a random transition in a conducting line, includes the steps of: making a first reference reflectometry measurement on the conducting line in order to deduce a reference time-domain reflectogram therefrom, identifying at least one characteristic of the reference time-domain reflectogram, making a second reflectometry measurement on the conducting line to obtain a second time-domain reflectogram, identifying the same at least one characteristic in the second time-domain reflectogram, and for each amplitude peak identified, determining a difference between the at least one characteristic measured on the reference time-domain reflectogram and the same characteristic measured on the second time-domain reflectogram, evaluating, from a plurality of successive measurements, whether the difference increases in absolute value, and, if this is the case, triggering a warning corresponding to the appearance of a random transition.
