Fault location on long power cables
Findings and experience concerning the use of submarine cables for long connections
In a few years’ time, high-voltage cables hundreds of kilometres long and extending from one end of Germany to another will become part of the country’s critical infrastructure. Maximising the availability of these cables is crucial, so any faults need to be located swiftly and reliably and the cables repaired with minimum delay. This goes beyond the capability of conventional fault location technology but, fortunately, special solutions are available for extra-long cables based on technology partly derived from a field in which long cables are commonplace: submarine cables.
