ABSTRACT:
A lightning protection device which is capable of avoiding electrical current, which is being induced in the blades of wind turbine, from being passed to parts of the wind turbine that may be damaged or destroyed by the electrical current. The electrical current is passed along by electrical conductors extending from the blades to a stationary part of the wind turbine. A flange for mounting the hub of the wind turbine to the main shaft is provided where the electrical conductors lead either through or past the mounting flange.
