This invention relates to a method for detecting and determining the position of faults using reflectometry in a wired electrical network comprising the following steps: inject a test signal into a cable in said network, retrieve a reflected signal on said cable, sample said reflected signal at a frequency Fe=1/Te, repeat the previous steps N times, where N is an integer number, for each injected test signal, retrieve n samples from the corresponding reflected signal, where n is an integer number, analyse M=n*N retrieved samples to detect and locate a fault in the wired electrical network. The method is characterised in that the retrieved samples are compared with an adaptive threshold defined for each diagnostic as a function of the test signal injected in the tested cable.
