摘要
A method for analyzing faults affecting a transmission line network includes at least one line segment having a plurality of ends, the method comprising the steps of: acquiring, at at least two ends of the line network, a measurement of a signal being propagated in the network, applying a time reversal to each signal measurement, for each segment of the line network, constructing a cost function dependent on the time and the distance from a point of the segment to an end of the network, searching for at least one extremum of the cost function over all of the segments of the line network and retaining the coordinates of the extremum, deducing therefrom the presence of a fault at a position and an instant of occurrence that are given by the coordinates of the extremum.
