Abstract
The invention relates to an apparatus for locating faults on subsea telecommunications links by determining the resistance of a conductor of the cable having a fault not being insulated from the sea. The apparatus is provided with two terminals, one for connection to one of the conductors of the subsea link and the other for being connected to the sea or to ground, through which terminals it is capable of delivering or receiving electrical power. The apparatus, on its own or together with another apparatus of the invention, is capable of automatically performing current and voltage measurements and it is capable of processing them automatically while making use of data from one or more databases concerning notably the resistance per unit length of the cable in order to locate the fault.
