摘要： Wind turbine blade comprising a lightning protection system, said lightning protection system comprising a first lightning receptor mounted near the tip of the blade and an electrical conductor electrically connecting the first lightning receptor and the base of the wind turbine blade. The lightning protection system further comprises a first aerodynamic fence attached to the wind turbine blade between the lightning receptor and the tip of the blade. In this way, a zone of smoother airflow is provided which makes a more effective target for lightning to strike, thereby avoiding damage to other parts of the blade.

摘要： A method for testing a lightning protection system in a wind turbine rotor blade is provided. The lightning protection system is contacted in the region of a rotor blade root. A measuring line having an electrically conductive tip is positioned in the interior of the rotor blade or outside on the rotor blade until the conductive tip is in contact with an element of the lightning protection system. A signal is fed via the measuring line and the signal arriving at the lightning protection system in the region of the rotor blade root is measured in order to check the mode of operation of the lightning protection system in the rotor blade.
