In a method, impulse response information indicative of an impulse response is determined based on an impulse introduced into a lightning conductor and characterized by an electromagnetic wave. The impulse response information representing at least a waveform and a travel time determined after the introduction of the impulse based on reflection thereof. Evaluation information is specified based on the determined impulse response information. The impulse response information is analyzed at least with respect to the represented waveform and travel time of the introduced and reflected electromagnetic wave. The evaluation information is indicative of whether or not the lightning conductor is functional. The determined evaluation information is output. Also disclosed are a device for practicing this method, a rotor blade for a wind turbine that includes at least one lightning conductor and a device for practicing the method, and a system with one or more devices for practicing the method.

Checking lightning conductors for wind turbines

A wind turbine, in particular an offshore wind turbine includes at least one hollow structural element, at least one cable inlet arranged in a bottom region of the hollow structural element. A first platform is arranged inside the hollow structural element, above the bottom region. At least one flow opening is arranged in the shell surface of the hollow structural element and penetrating the shell surface. At least one active control element is flow-connected to the flow opening to affect a media exchange between the interior of the hollow structural element and the exterior of the hollow structural element.
