HOW TO HANDLE THOUSANDS OF INSPECTION IMAGES WITHOUT LEAVING YOUR OFFICE

Energinet.dk is a non-profit organization under the Danish Ministry of Energy, operating 6,800 kilometres of electricity supply grid in Denmark and ensuring that the electricity supply is kept operational both in the short term and in the long run. In recent years, Energinet.dk has come to rely increasingly on drone inspections for the maintenance of power lines, and the Scopito software platform has proven to be a valuable tool for this kind of work.

Mads Lykke Pedersen, who is in charge of inspecting all power lines in Jutland, explains: “Drone inspections are a clever, safe and cost-effective way of doing power line inspections, but they tend to generate vast numbers of images. In fact, once you’re done with an inspection run, you can have thousands of images on your drive. This is not very useful unless you can somehow tag and sort these images in a useful way. We use Scopito for this.”

In the case of the power lines crossing the Limfjord in Northern Jutland, the power of the Scopito platform became evident. Using drones, Energinet.dk managed to capture thousands of images of power lines crossing the water at a height of almost 100 meters without the need for cranes or for interruptions to the power supply.

“For instance, we found damage from lightning strikes that we could inspect at our leisure using the images captured by the drones,” says Mads Lykke Pedersen. “And because the images were GPS-tagged, we could pinpoint precisely where the problems were, which will make it much easier and more cost-effective to perform the necessary repairs when we have to.”

Let the experts stay in their office
Energinet.dk also found evidence of wear on the conductor wires of a kind that hadn’t been noticed before. “We found that the conductors had a surface that seemed almost to have been sand blasted,” says Mads Lykke Pedersen. “For that we needed outside experts to take a look at the damage – specifically, an expert placed in Canada. But where we would have had to fly him in back in the old days, now we could just email a web link to him and ask him to take a look at the images on his monitor in his own office. This saved a lot on travel and fees and cut down the time for the diagnosis quite significantly.”

Scopito as a tool for traditional inspection images
But the strengths of the platform are not confined to drone images, however. Energinet.dk often uses traditional helicopter inspections and ground-based photo shoots to document the condition of power lines, and Scopito is ideal for storing and sharing this type of inspection data.
“We perform more and more drone inspections, but we also still take images using helicopter runs and photography from the ground. After that it’s just a question of uploading the GPS-tagged images to the Scopito platform. That way we can keep full control of our inspection data and share them with colleagues and repair crews.”
