Abstract: A wind turbine blade comprising a main blade portion having a longitudinal axis that extends between a root end and a tip end, wherein a leading edge and a trailing edge extend between the root end and the tip end, and a conductive blade tip module mounted to the tip end of the main blade portion; wherein the tip end is truncated and has a blade tip interface that defines an outer edge, and wherein the blade tip module is configured to fit against the blade tip interface such that a lip of the blade tip module overlaps the outer edge of the blade tip interface. Since the blade tip module is configured to overlap the tip edge of the blade, this protects the junction between the two components from erosion due to weathering.

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 having root and tip portions having insulation with different electrical breakdown voltages. The lightning protection system may comprise 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; and/or a plurality of inboard down conductor cables and a diverging electrical junction.

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.
