Patent ID: 8620605

Claim:
A method for detecting and determining a position of faults using reflectometry in a wired electrical network comprising: injecting a test signal e(t) into a cable in the electrical network, a timing of successive injections being controlled by a synchronization module that generates an emission clock signal and a reception clock signal; retrieving a reflected signal on said cable; sampling the reflected signal at a frequency Fe=1/Te, where Te is a sampling period; counting a number of samples obtained for the reflected signal and comparing the number of samples obtained with a number n predefined as a function of a length of the cable or the electrical network to be diagnosed, where n is an integer; repeating the injecting, the sampling, and the counting steps N times; reconstituting the reflected signal from n*N samples obtained, analyzing the reflected signal to detect a fault, wherein, the successive injections of a test signal into a cable of said network are desynchronized from the sampling period Te by a duration Î´ 1 , and a first sample of the reflected signal for each injecting signal is retrieved and desynchronized by a duration Î´ 2 from the duration Î´ 1 , the following samples of said reflected signal being retrieved with a constant delay that is a multiple of the sampling period Te relative to said first sample.
