Abstract :
A solution of magnetic fields for an amorphous core transformer has been tried using the homogenization technique. The technique, which is derived by applying asymptotic expansion to the standard finite element method, is helpful to analyze a joint part of an amorphous core transformer microscopically. A butt-lap-step joint type of lamination method is modeled and its equivalent reluctivity is calculated to analyze various quantities of the magnetic fields
