Patent ID: 8554499

Claim:
A method for locating a defect in an electric link comprising: transmitting, at a first moment, an electric signal having a predetermined propagation speed at a start from an end of the electric link; detecting, at a second moment, reception of an echo of the electric signal; establishing a model of variation of the electric signal and its echo propagation speed in the electric link as a function of a length of electric link through which the transmitted electric signal and its echo have flowed; and estimating a location of the defect as a function of 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, wherein the model includes a plurality of propagation speeds of the transmitted electric signal and its echo, the plurality of propagation speeds corresponding to a plurality of lengths of the electric link through which the transmitted electric signal and its echo have flowed, and the plurality of lengths of the electric link including lengths of the electric link shorter than a total length of the electric link.
