Abstract

This paper describes possible procedures for computation of static self-inductances and static mutual inductances in nonlinear magnetic systems. The procedures are based on numerical calculation of magnetic field with finite element method. Previously mentioned calculations are carried out for various current excitations. Inductances are calculated with magnetic flux of coils and with magnetic field energy. Single-phase transformer is used as a test model for verification of inductance calculation procedures. Calculated results of inductance values, magnetic fluxes and magnetic field energy are estimated in regards to the measurements of the geometrically and physically identical realistic transformer.
