Calculation of Power Transformer Losses by Finite Element Method

In this paper, simulation of three-dimensional power transformer and calculation of the losses will be completely reviewed. In this way, at first, the importance of the survey about transformer losses will be briefly discussed. After that, all of the losses in the transformer will be studied and a brief explanation for each one will be given.so, transformer losses will be calculated by three-dimensional finite element method. Analysis of element method, enable high precision without many conditions. At last, the no load and full load losses of the transformer will finite element method has calculated and the results will provide.

I. Introduction

Power transformers is one of the most expensive element in the power system. Hot spot Temperature of transformer is directly related to environment temperature and the load of transformer. In addition, transformer hot spot temperature is one of the most important parameters in determining the insulation life time. Therefore, it is necessary to have the thermal model of the transformer and to determine the temperature of its different points under different operating conditions. On the other hand, the losses of each electric vehicle are sources of heat production. As a result, in this paper, the types of losses of the transformer are investigated [1].
