Calculation of Current Transformers (CTs) magnetic and thermal properties are very complex due to the complexity of their construction, different properties of their materials and non-linearity of core B-H curve. Finite Element Methods (FEMs) are very capable and reliable methods for these problems solution, such as Ansys software. In this study Ansys software is applied in analysis of an 800-400/5-5 CT. These analyses consist of 2D static normal, open circuit and short circuit condition of CT. Magnetic and thermal analysis are made and the results will be discussed.
