A hybrid method for determining the reluctivity tensor components of Goss textured ferromagnetic materials

摘要

For anisotropic materials, the magnetic field vector Hand the flux density vector B are parallel with each other only along a few distinct directions. When performing unidirectional measurements, only the component of B along the direction under consideration is measured. It is not possible to deduce the angle between B and H from unidirectional measurements alone. For ferromagnetic materials having a Goss-texture, as most transformer steels have, this paper demonstrates a way to compute this angle a posteriori, by the combination of measurements with a physical anisotropy model.
