Abstract
A wind turbine blade is described having a lightning bypass system located at the root end of the blade. The lightning bypass system comprises a stay bolt formed from an electrically insulating material having a conductive core. The conductive core of the stay bolt provides a conductive path for a lightning down conductor system through the root end of a wind turbine blade to the turbine hub or nacelle, bypassing any sensitive root end components of the wind turbine blade.
