Abstract :
A model is given and a periodic boundary condition is adopted to analyze magnetic fields of a delta type shunt reactor. An approximate three-dimensional finite-element method that combines some axisymmetric fields and a two-dimensional field is then applied. It is found that the flux in the yoke concentrates on the part that is near the legs. The flux density heightens as the legs is approached, and rotational magnetic flux occurs in the parts joined by a leg and the yoke. All flux density waveforms contain mainly third harmonics. It is found that there is rotating flux in the yoke, which causes increased core losses
