Starting in 2023, Enertrag Operation will offers its drone inspection service in France as well. Together with the Swiss company Sulzer & Schmid Laboratories, Enertrag Operation has combined rotor blade inspection and LPS measurement in a procedure using a drone.
While a drone automatically flies along the rotor blades of the wind turbine, two processes are carried out simultaneously: A high-resolution camera takes pictures of the rotor blades and a field strength meter measures a realistic voltage along the blade applied to the lightning protection of the blade root by means of a high-voltage generator. With both methods, it is possible to identify and precisely localise damaged areas on the blade and/or LPS.
