Abstract: A method for locating a defect in an electric link includes measuring at least one part of components of an electromagnetic field in a vicinity of an estimated location of the defect at plural places along the link; deducing, via a processor, from the measuring an estimation of variation of at least the part of the components of the electromagnetic field along the electric link in a vicinity of the estimated location of the defect; and estimating, via the processor, a new location of the defect as a function of the estimated variation of at least the part of the components of the electromagnetic field.

Abstract: A method for detecting a defect in an electric link, which transmits, at a first moment, an electric signal having a predetermined propagation speed from an end of the electric link, and detects, at a second moment, reception of an echo of the electric signal. The method further establishes a model of the variation of the electric signal propagation speed in the electric link on the basis of the length of the link through which the signal flows, and estimates a first location of the defect based on the difference between the first and second moments, on the predetermined propagation speed at the start, and on the speed variation model in the link.
