Abstract

A nacelle (14) for a wind turbine (10) includes: an external surface (40) exposed to a magnetic flux induced by lightning, an electrical generator (15) rotating about a rotational axis (Y), the electrical generator (15) comprising a rotor (4), a stator (3), an airgap (5) separating the rotor (4) and the stator (3), and a plurality of electrical conductors (24) wound in the rotor (4) or the stator (3) adjacently to the airgap (5), a lightning protection arrangement (100) including at least one waveguide (110) between the rotor (4) and the stator (3) and interposed between the external surface (40) and the airgap (5) for providing a shielding to the electrical conductors (24) from the magnetic flux induced by lightning.
