Abstract
A lightning receptor arrangement for a wind turbine rotor blade arrangement includes a receptor element for receiving a lightning strike, a drainage channel extending from an interior cavity of the blade through the receptor element to an outside surface of the blade, and an electrically conductive connection to a down conductor of a grounding arrangement of the wind turbine. The receptor element is arranged at a point of origin of a vortex generated during rotation of the rotor blade.
