Computation of Self- and Mutual Inductances of Open-core Transformers Using a 3D Integral Equations Approach

In this paper computation of self and mutual inductances of open-core transformers is presented. Influence of ferromagnetic core is described with magnetostatic integral equations and quadrilateral 3D elements. Magnetization is assumed constant over quadrilateral element. Non-linear behavior of the ferromagnetic material is modelled employing iterative procedure. Results of the computation of inductances of open core instrument transformer based on 3D integral equations is benchmarked against commercial software Ansys Maxwell.
