The invention provides a wind turbine comprising a nacelle a rotor comprising at least one blade attached to a hub and an electrical supply structure for supplying electrical power from the nacelle to the rotor. The rotor is rotatably connected to the nacelle about an axis of rotation. The supply structure comprises a switch which has a connected mode in which the nacelle and the rotor are electrically connected and a disconnected mode in which the nacelle and the rotor are electrically disconnected. Furthermore the switch is adapted to change from the disconnected mode to the connected mode when the rotor does not rotate. |
