Magnetic-field-intensity and current-density distributions in transformer windings

One single-layer and two four-layer example winding structures are used to illustrate the impact of excitation frequency on the magnetic field intensity and current density distributions in transformer windings. By plotting the distributions as phasors in three-dimensional isometric plots, greater insight is gained into the origin and behavior of eddy currents. This insight enhances the design engineer´s ability to understand and evaluate the available design options
