Abstract: A wind turbine blade comprising a lightning protection system, which is at least partly disposed in an inboard portion of the blade. The lightning protection system comprises a down conductor cable portion and a supporting component to hold the cable portion in free space in a position near or on a camber line of the blade aerofoil section, so that the cable portion is spaced apart from at least one electrically conductive structural component. The lightning protection system may comprise a plurality of inboard down conductor cables and a diverging electrical junction; and/or a down conductor cable having root and tip portions having insulation with different electrical breakdown voltages.

Abstract: The present invention provides a wind turbine comprising a lightning protection system for providing an electrical conduction path suitable for conducting lightning from the rotor to electrical ground. The lightning protection system comprises a shroud which is electrically coupled to a wind turbine bearing housing and a wind turbine hub and/or the front end of the main shaft. The shroud forms part of the electrical conduction path so to electrically couple a wind turbine rotor to the bearing housing via a short circuit path that bypasses the bearing arrangement.

Abstract: A wind turbine rotor blade having a blade shell with a generally chordwise layup of fibre plies and a generally spanwise spar cap. A lightning conductor extends over the spar cap, and the spar cap includes conductive material. An equipotential bonding element electrically bonds the lightning conductor to the spar cap. The equipotential bonding element extends between an outboard edge of one stack of the fibre plies and an inboard edge of an adjacent stack of the fibre plies, which overlap to define an overlapping edge region.
