Abstract
A rotor blade for a wind turbine includes a blade skin forming a suction surface and a pressure surface. An electric heating arrangement has a heating strip with a width-thickness relation configured to reduce bonding between ice and the blade skin by electrically heating a respective surface of the blade skin and to conduct lightning-strike currents of at least 10 kA. An energy transfer arrangement supplies electrical energy to the heating arrangement. An integrated lightning arrangement includes a lightning receptor mounted to a tip section of the blade and electrically connected to the heating strip such that the lightning strike is conducted from the lightning receptor to the heating strip. A grounding device is connected to a grounding arrangement of the wind turbine such that electrical energy of the lightning strike is conducted from the heating strip through the grounding device and into the grounding arrangement.
