Abstract
A method for detecting and locating a fault affecting an electrical cable includes the steps of (a) placing a first sensor and a second sensor along the cable, the second sensor being an acoustic sensor; (b) detecting the occurrence of the fault with the first sensor at a first time, and with the second sensor at a second time; (c) taking into account a propagation speed of an acoustic wave generated by the fault; (d) estimating a position of the fault depending on the first time and on the second time, on the basis of the propagation speed resulting from step (c); (e) determining a reference propagation speed depending on the position resulting from step (d) of the fault, and comparing said reference propagation speed with the propagation speed taken into account in step (c); and, (f) depending on the comparison, validating the position resulting from step (d) or reiterating steps (c) to (f) while adjusting, in step (c), the propagation speed taken into account.
