Abstract :
A power transformer operating in electric network is supplied by voltage source. When analyzing leakage flux and magnetic forces of the power transformer applied to windings, the field-circuit coupled 3D finite element method is needed because of the drawbacks of magnetic dipole model and 2D finite element method. The models were used for simulating and analyzing leakage flux and magnetic forces data sets. It is the base for further studying on magnetic flux leakage and magnetic forces inspection.
