Fault location on long submarine cables, pinpointing on long cables

Abstract: the present invention relates to a fault location system () for localization of a fault in a submarine power cable (). the fault location system () comprises a pulse generating device () for generating an electric pulse signal and a signal analyzing device () configured to determine the localization of the fault by analyzing a reflection signal resulting from the electric pulse signal being reflected from the submarine power cable. the pulse generating device () comprises a hv dc signal generator (), a power cable () connected between the signal generator () and an output terminal () of the device , and a switch () controlled by a control circuit. the control circuit () is configured to:
