Abstract
A wind turbine blade is described having a lightning protection system wherein a lightning down conductor is conductively coupled to at least one blade root bushing provided at the root end of the blade. The use of the blade root bushing as part of the conductive path of the lightning protection system allows for a structurally sound and reliable connection of an internal down conductor to an external lightning protection system and/or to a suitable ground connection at the blade root end.
