Abstract

The present invention relates to a fault location system (10) for localization of a fault in a submarine power cable (1). The fault location system (10) comprises a pulse generating device (20) for generating an electric pulse signal and a signal analyzing device (30) 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 (20) comprises a HV DC signal generator (22), a power cable (25) connected between the signal generator (22) and an output terminal (21a) of the device 20, and a switch (28) controlled by a control circuit. The control circuit (29) is configured to:- turn the switch (28) off in order to charge the power cable (25) with power from the HV DC generator (22);- turn the switch (28) on in order to discharge the power of the power cable (25) into the submarine power cable (1).
