The Smart Cable Guard solution continuously monitors and instantly detects the exact location of faults in medium-voltage (MV) power cable systems.
Real-time cable status information can shorten maintenance time, enhance the stability of medium-voltage power cable systems, and reduce overall service costs for utility and industrial asset owners.
DNV will unveil the latest technological advancements in its Smart Cable Guard solution at CEPSI (Asia Pacific Electric Power Industry Exhibition) in South Korea from October 26 to 30.
DNV GL, a leading global authority on energy consulting and testing, today announced the latest advancements in its Smart Cable Guard solution. In addition to its existing capabilities that enable system operators and industrial asset managers to detect and locate partial discharges online, Smart Cable Guard can now pinpoint the exact location of faults in medium-voltage cable systems with 1% accuracy, significantly reducing repair time. This real-time insight allows operators and asset managers to significantly reduce the time customers are affected by faults and, in certain situations, reduce the frequency of impacts, ultimately lowering overall system costs.
This solution reduces maintenance costs, minimizes power outages during daily use, mitigates negative publicity and claims, and enhances the operator's reputation for reliable and innovative grid management. Integrated into a single solution, Smart Cable Guard can detect and locate any fault and issue an immediate alert, even without a short-circuit current, and is unaffected by grid grounding or short-circuit cable levels. It also has the ability to instantly detect the location of intermittent and hidden faults.
Denny Harmsen, Senior Innovation Consultant at Alliander, one of the Netherlands' leading power grid utility companies, said: "Smart Cable Guard has proven to be an attractive solution for accurate and rapid online detection of power grid faults. Therefore, we are using DNV GL's solution to protect our circuits and will be adopting more solutions."
Dr. Fred Steennis, Chief Consultant and Power Cable Expert at DNV GL, stated, “In urban environments where power outage costs are high, medium-voltage power cables are the most important assets for utilities, while in environments owned by industrial asset owners, failures can lead to severe damage and economic losses. Off-grid monitoring of these cables is like a security camera taking pictures once a year, while Smart Cable Guard’s new real-time insights provide operators with continuous monitoring of their cable networks and give them the right information to take immediate action.”
DNV GL invests 5% of its revenue in research and innovation, such as developing joint venture industry projects with industry partners, of which Smart Cable Guard is one.
