MAKING DRONES SMARTER: patented technology for contactless lightning protection measurement and visual inspection of wind turbines - validated and verified by TÜV SÜD.


TOPseven offers customers automated, drone-based visual inspection and contactless lightning protection measurement of onshore & offshore wind turbines. The patented process is validated and verified by TÜV SÜD. The user is enabled to use the technology independently.

The inspection of wind turbines reaches a new level with the patented TOPseven technology: automated, drone-based visual inspection including contactless lightning protection measurement for rotor blades and tower of onshore and offshore wind turbines. In the process, specialized personnel enable the user to apply the technology independently.

The TOPseven technology is unique on the market worldwide: validated and verified by TÜV SÜD and thus applicable as an alternative inspection method (according to BWE guideline).


The users are enabled by our experts in a short training to use the technology independently. After a short calibration flight, the exact flight route is calculated and the drone flies autonomously.


For visual inspection and contactless lightning protection measurement, the turbine only needs to be stopped once. This saves time and costs.


The drone provides gapless, high-resolution and reproducible images with consistent minimal overlap. Automated reporting is performed according to the industry standards.

Lightning protection measurement

Special sensors can detect the functionality of the contactless lightning protection system. In addition, exact localization of the damaged area is possible. Lightning protection measurement can thus be performed faster, more efficiently and more accurately.
