20100211338 | METHOD AND DEVICE FOR ANALYZING ELECTRIC CABLE NETWORKS USING PSEUDO-RANDOM SEQUENCES - The invention relates to a method and a device for analyzing electric cable networks in order to detect and locate defects in the cables comprising at least one branch connection from which N secondary sections extend. The method involves injecting into the network, at a plurality of injection points E, pseudo-random sequences of digital signals PNi(t) that are de-correlated from each other, and collecting, at one or more observation points Sj, composite time signals Rj(t) generated by the circulation of the output sequences and the reflections thereof in the impedance discontinuities of the network. The correlation between the composite signals and the time-offset pseudo-random sequences is then computed, and the positions of correlation peaks are sought to deduce therefrom the positions of defects in the network by taking into account the signal propagation speed in the network. | 08-19-2010 |
20110015882 | METHOD FOR IMPROVING FAULT DETECTION AND POSITIONING PRECISION USING REFLECTOMETRY IN A WIRED ELECTRICAL NETWORK - 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: | 01-20-2011 |
20150025820 | METHOD OF MEASURING THE AGING OF ELECTRICAL CABLES - A method comprises: injecting at an instant a reference signal at an injection point of said assembly, the reference signal having been obtained beforehand by injecting an initial signal at the injection point at an instant, by a measurement of the reflected signal resulting from this injection, and by the time reversal of the measured signal; measuring a reflected signal resulting from the propagation of the signal in the assembly of at least one cable; and determining the aging of the assembly of at least one cable between the instant and the instant, the aging being deduced from the measurement of the reflected signal. | 01-22-2015 |
