Abstract
A lightning protection system is provided for a wind turbine. The wind turbine has an electrically grounded structure part, a main shaft electrically and mechanically connected to the grounded structure part, a blade hub rotationally connected via a main bearing to the main shaft and blades connected to the blade hub. The lightning protection system includes a down-conductor attachable inside one of the blades and a high voltage conductor for guiding lightning current, wherein a first end of the high voltage conductor is in electrical communication with the down-conductor. The lightning protection system also includes a high voltage contact attachable inside the main shaft, wherein a second end of the high voltage conductor is in electrical communication with the high voltage contact. Lightning current is guided from the down-conductor via the high voltage conductor to the high voltage contact.
