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.

The future is electric

An important step in CO2 reduction is the use of electric mobility: emissions are reduced, the air we breathe becomes cleaner and the quality-of-life increases. Germany wants to be one of the pioneers in the field of electric cars and is making effort in achieving this through supporting programs. If the use of e-mobility is to be sustainable, energy from renewable resources must be used for the electricity required.

Patent grant contactless lightning protection measurement

TOPseven’s unique measuring method for contactless lightning protection measurement of wind turbines has not only been validated and verified by TÜV SÜD, but has also, 5 years after the application, been granted the European patent on July 21, 2021 (EP 3 596 570).

Wind energy in Germany

Why is Germany perfect for wind energy? To answer this question, we should first understand the fundamental rules of constructing the perfect wind farm and what conditions should be met.

TOPseven TUEV SUED Validated and Verified

Contactless lightning protection measurement

Validated and Verified by TÜV SÜD

TÜV SÜD’s independent validation and verification confirmed that the measurement system is suitable as an alternative test method for the section of a WT’s lightning protection system extending from the receptors (lightning arrestors) to the blade flanges of the rotor blades in accordance with the Technical Guideline of the German Wind Energy Association.


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.
