Abstract:
A wind turbine including a hub to which the rotor blades are arrangeable, wherein the hub is rotatable around a rotating axis is provided. The wind turbine further includes a generator including a rotor arrangement and a stator arrangement, wherein the rotor arrangement and the stator arrangement are rotatable with respect to each other around the rotational axis. Further the rotor arrangement is coupled to the hub. The wind turbine further includes a grounding system which is fixable to a nacelle of the wind turbine, wherein the grounding system is configured for transferring lightning current between the rotor arrangement and the nacelle and for providing an EMF shielding of the generator, wherein the generator is arranged along the rotational axis of the hub between the hub and the grounding system.
