Mid-September and the sun was shining in Baden-Württemberg near Zollhaus (Blumberg). A power line runs through the heavily forested area and has to be inspected regularly. Normally, helicopters have to go up in the air every two years to do this. On foot, surveyors are even in action annually at the overhead lines and have to “fight their way” on the ground to check lines and pylons.
The southern Baden electricity operator ED Netze is therefore already using drones for targeted inspections as a faster and cheaper alternative. The company deploys one of its eight trained drone pilots for this purpose. So now also at Zollhaus. In a joint project with FlyNex and Globe UAV, the use of drones for the inspection of power lines was tested.
The special thing here: The drone was to fly out of sight of the drone pilot (BVLOS), and the entire route automated. Over 25 km of overhead power lines and around 100 power poles were successfully inspected by drone and in BVLOS (Beyond Visual Line Of Sight) in a three-hour mission.
We are very happy about the success of this project. It shows how aerial inspections can be carried out more easily, efficiently, and sustainably with unmanned aerial vehicles.
