Mature and proven, DNV’s Smart Cable Guard digital monitoring platform is trusted to protect medium-voltage cable networks in many different applications around the world.

Electricity distribution networks

Electricity systems are getter smarter. Yet they are still overwhelmingly based on ageing assets and passive cable networks. Smart Cable Guard is a first step towards digitalization and self-managed networks. It precisely locates faults and weak spots in cables, and supports decision making in routing and maintenance. As well as reducing customer minutes lost, it enables optimized, proactive maintenance strategies by providing real and fact-based cable health data so you can focus investment and resources on those cables that actually need repairing or replacing.

Large industrial facilities

Industrial facilities such as steel works, oil refineries and large factories depend on a reliable supply of electricity. Any interruptions in that supply mean production shutdowns that reduce productivity, revenues, damage your reputation and could eventually lead to cancelled contracts. Smart Cable Guard provides real-time, round-the-clock monitoring of feeder cable networks, allowing you to maximize efficiency, minimize downtime and operate at the top of your business potential for longer.

Public transport systems

For mass transit and metro rail systems, reliability is king. A single cable failure can disrupt your whole network – leaving thousands of upset passengers stranded in potentially dangerous conditions and looking for a more dependable option. Smart Cable Guard’s active digital power cable management is already helping keep numerous transit systems running around the world. By pinpointing faults and weak spots in power feeder cables, it helps these networks target maintenance and repairs to minimize the number and duration of service interruptions.

Onshore wind farms

The sensor-based Smart Cable Guard system has been optimized for over 20 years and the platform runs on a well-trained algorithm that accurately distinguishes weak spots from noise sources on feeder cables. Through continuous digital monitoring, revenue losses and costs of locating and repairing cable failures can be reduced significantly, enabling wind energy suppliers to come back online faster, maximizing performance and profitability. In addition to improving the levelized cost of energy (LCOE) for wind farms, the platform improves safety by providing insights about the health of the cables and reduced time in the field for engineers.
