XL-CFL – BAUR cable fault location for long submarine & underground cables
Indispensable and robust, but sadly not indestructible: Long land and submarine cables for global power supply
Due to the growing demand for power and increasing dependence on renewable energy – more and
more of which is being generated offshore – submarine power cables are becoming indispensable for a reliable energy supply. Among experts, submarine cables are classified as critical infrastructure. Why critical? Firstly due to the harsh environment in which they are installed. Secondly – and this is also the most common cause of faults – submarine cables are exposed to mechanical stress, such as currents, fishing, or heavy ships' anchors, at irregular intervals and at all water depths, which can result in significant damage.

Security of supply as the top priority with your proven system for fast and efficient cable fault location
Since 2010, BAUR has been developing individual product solutions for fast and efficient fault location on long land and submarine cables. With the powerful systems and extensive expertise of BAUR specialists, critical cable faults on submarine cables have been located rapidly, efficiently, and precisely in recent years. You too can rely on BAUR expertise and the high-performance technologies that have been tried and tested worldwide.
Cable fault location outside the standard
What should you do when the favoured Time Domain Reflectometry method cannot be used?
The normal fault location methods Time Domain Reflectometry (TDR) in particular, but also the secondary/multiple impulse method (SIM/MIM) cannot always be used in very long cables (especially those with cross-bonding joints). One reason for this is that the measurement pulse or its reflection is too strongly damped over the long distance, making it very difficult to evaluate the pulse. Another possible cause is the high capacitance of the cable, which makes it difficult to achieve a usable pulse discharge with the SIM/MIM method because the capacitance of the surge capacitor should be significantly higher than that of the cable.

What is the technical article about?
The growing use of renewable energies and the transition to e-mobility are increasing the dependency on electrical energy. One source of renewable energy is offshore wind farms, which are connected to the mainland by long cables. However, such high-voltage direct current transmission (HVDC) cables are also used on land. Any faults occurring on these long lines have enormous consequences for a country's electrical infrastructure.
Keeping downtime to a minimum and quickly locating these cable faults requires effective measurement technology. This technology must be versatile, cover various fault location methods, and be capable of adapting to the cable length in order to facilitate reliable fault detection. But which device covers the various measurement methods and can be adapted to the cable length?
