500 kV HVDC TPI & Power Cable Monitoring
AP Sensing’s Distributed Acoustic Sensing (DAS) technology was recently deployed by Korean Electric Power Corporation (KEPCO) to monitor the power cable link. The asset is a 500 kV HVDC transmission line, approximately 35 km in length. KEPCO decided to deploy AP Sensing’s DAS to monitor the asset and receive alerts in case of Third Party Interference (TPI) activities.

Third Party Intrusion & Power Cable Monitoring
AP Sensing’s technology was deployed by RTE to monitor a 225 kV underground power cable link located in the west of France. The link is approximately 39 km long and monitored for Third Party Intrusion (TPI) activities plus cable faults using our Distributed Acoustic Sensing (DAS) system, as well as hotspots using our Distributed Temperature Sensing (DTS) system. The power link installation is surrounded by frequent agricultural activities that pose no harm to the cable. To mitigate the risk of increased false alarms from these activities, similar events were simulated to test the system based on soil mixing and harvesting agricultural machines.

Power Cable Fault Detection & Location Analysis
For large power cable assets such as subsea cables, windfarm export cables or HV onshore transmission cables, finding cable faults rapidly is crucial to minimizing downtimes caused by these faults. Fiber optic Distributed Acoustic Sensing (DAS) is a key enabler for this task, as it pinpoints the exact location of an occurring cable fault if permanently installed or post-fault during thumping/flashover generation campaigns. The following examples summarize AP Sensing’s recent experience providing fault-finding services (both online and offline) with our DAS system.
