See full text

A wind turbine blade includes: a blade body; a down conductor extending along a longitudinal direction of the blade body; and at least a pair of magnetic field sensors disposed inside the blade body and at opposite positions across the down conductor, a pair of magnetic field sensors being configured to detect a local magnetic field at each of the positions. At least the pair of magnetic field sensors includes: a first sensor disposed on a first axis passing through an installation position of the down conductor in a cross section intersecting the longitudinal direction; and a second sensor disposed on a second axis passing through the installation position and being orthogonal to the first axis in the cross section.
