Abstract:
Disclosed is a wind turbine blade comprising a first blade section and a second blade section connected to the first blade section. The wind turbine blade comprises a first down conductor for conducting lightning current to ground. The blade further comprises one or more lightning receptors at or in proximity of an external surface of the wind turbine blade. A smallest distance from a first lightning receptor of the one or more lightning receptors to an interface between the first blade section and the second blade section may be less than or equal to a chord length of a chord of the wind turbine blade at the interface between the first blade section and the second blade section.
