Abstract
A wind turbine rotor blade has a spar cap including conductive material, and a lightning conductor extending over the spar cap. There is a non-conductive layer between the lightning conductor and the spar cap. An equipotential bonding element electrically bonds the lightning conductor to the spar cap. The non-conductive layer is discontinuous to define a gap, and the equipotential bonding element extends through the gap.
