Abstract

The paper presents a numerical method based on the finite elements to model the electromagnetic phenomena in two different special transformers. 2D FEMM model of existing resistance welding transformer will be verified with experimental test results. The combined instrument transformer will be modeled and calculated with original FEM-3D program developed at the Faculty of Electrical Engineering and Information Technologies - Skopje. The FEM results will be coupled with originally developed transformer transient model. The test results obtained for the real resistance welding transformer will be used to verify the performance of the developed transient model. Next, the verified model will be used for metrological analysis of the combined instrument transformer..
