The field and power losses computation in structural components of HV power transformer

The paper presents the discrete model of the structural components HV transformer. Transformer model is created as 3D geometry. The paper presents the methodology of the model generation for the full geometry of the transformer flat bars and flat bars connectors. The electromagnetic field analysis leads to the identification of the points with high dense losses of the structural components of 3D transformer geometry. The field and power losses distribution computation is essential for further investigations leading to the design of structural components. Proper designing procedure of the elements it is so important and show the strong influence on the total transformer power losses terms.
