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.

energy consult Prüfgesellschaft trusts in the innovative solution from TOPseven

Die innovative TOPseven-Technologie ermöglicht der energy consult Prüfgesellschaft effiziente und hochqualitative drohnenbasierte visuelle Inspektionen und Blitzschutzprüfungen an den Rotorblättern von Windenergieanlagen. Dies erfolgt mit eigener Drohne und eigenem Personal, da bei der Lösung von TOPseven erstmals keine spezialisierten Piloten mehr erforderlich sind: Vor dem Inspektionsflug wird mittels patentierter Technologie eine exakte Flugroute berechnet, so dass die Drohne die Anlage autonom abfliegt.

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.

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.
