Abstract

A mathematical model for leakage reactance calculation using magnetic field analysis is presented. An integral equation for the modeling of unbounded field problems, with constant magnetic permeability of the core, is derived. By the solution of the equation, a 3D quasistationary field has been analyzed and the reactance has been computed. A computer program has been worked out and implemented for a personal computer. Applications have been made for leakage field analysis in reactors with or without magnetic cores. Results of these calculations are presented and compared with measured values
