Come meet the poster presenters to ask them questions and discuss their work

We would like to invite you to come and see the posters at our upcoming conference. The posters will showcase a diverse range of research topics, and will give delegates an opportunity to engage with the authors and learn more about their work. Whether you are a seasoned researcher or simply curious about the latest developments in your field, we believe that the posters will offer something of interest to everyone. So please join us at the conference and take advantage of this opportunity to learn and engage with your peers in the academic community. We look forward to seeing you there!

PO297: Electric Fault Detection and Localization in Submarine Power Cables Using Distributed Acoustic Sensing

Simon De Rijcke, Project Lead, Marlinks


Detection and localization of electrical faults in power cables can be challenging in a submarine environment. We have conducted a series of tests to evaluate the effectiveness of Distributed Acoustic Sensing (DAS) for detecting and localizing electrical faults in a submarine cable. Two distinct types of defects were intentionally applied to a buried and submerged cable: a defect in the outer serving and a defect in the insulation. Subsequently, a cable thumper was connected to generate a short-circuit and arc at the fault location, thereby inducing acoustic emission in the cable. To capture these vibrations and acoustics, a DAS system was connected to the optical fibers embedded in the power cable. The DAS system successfully detected the acoustics caused by the arc-for both defects. Furthermore, at a high measuring frequency, we observed the resulting shockwave traveling through the cable, enabling accurate fault localization along the cable. The proposed method offers a non-intrusive solution for electrical fault detection and localization in electrical submarine cables.
