Abstract
System and method for locating a fault on a line comprises a sampler that samples a pulse from the fault, the sampling being carried out at a predetermined sampling rate. A differentiator produces a differential or derivative of the pulse, and an analyzer obtains timing information from the derivative, from which it is possible to locate the fault knowing the total length of the line and the wave propagation rate.
