Autonomous drone inspection: AI enables, for the first time, customers to perform independent automated drone inspections. An international patent-protected technology for visual inspection and contactless lightning protection measurement for on- and offshore wind turbines.

Drone License

With the new EU Drone Regulation the “small drone license” is required if the drone weighs more than 250g – regardless of whether the drone is used privately or commercially. This replaces the certificates of competence of the countries.

EU Drone Regulation

The new EU Drone Regulation EU Drone Regulation that forces in January 2021 defines basic rules for all EU countries. This replaces specific drone laws from single countries. There will be also in future state-specific requirements that must fulfilled in addition.

The future of drone technology

According to “airdronecraze“, a website of a partner advertising program of Amazon Services LLC, drone technology instead has seven potential generations – most of the current technology is in the fifth and sixth generation.

Contactless lightning protection measurement

Today, professional industrial climbers are checking the condition of the blades and lightning protection. The low-ohmic electrical resistance between the arresting devices in the blades and the ground connection lug at the base of the tower are measured.


Drone-based Inspection


Drones are increasingly being used as an alternative for the inspection of wind turbines. TOPseven’s AI takes the technology to the next level: The autonomous drone inspections document damages and identifies possible defects in the lightning protection system.


Independent use of fully autonomous drones by the customer, without specialized pilots.

Due to the independent monitoring via AI the customer doesn’t require a specialized pilot for the autonomous drone inspection. Thus, the customer needs a minimum training to get started.

Autonomous drone based inspection only requires a single stop of the wind turbine.

For the visual inspection of all blades and the tower, as well as the contactless measurement of the lightning protection, the wind turbine only needs to be stopped once.

Possible defects are being identified and located by special contactless sensors.

In only a few minutes the TOPseven drone checks the lightning protection of the system - contactless. Special sensors detect the defect and can exactly localize the interruption.
