1. A nacelle for a wind turbine comprising:
a surface exposed to a magnetic flux induced by lightning;
an electrical generator rotating about a rotational axis, the electrical generator comprising a rotor, a stator, an airgap separating the rotor and the stator, and a plurality of electrical conductors wound in the rotor or the stator adjacently to the airgap; and
a lightning protection arrangement including at least one waveguide between the rotor and the stator and interposed between the surface and the electrical conductors for providing a shielding to the electrical conductors from the magnetic flux induced by lightning, wherein the at least one waveguide extends between a first plate connected to the stator and a second plate connected to the rotor that faces the first plate, wherein a distance between the first plate and the second plate defines a width of the at least one waveguide.
