Power transformer thermal analysis by using an advanced coupled 3D heat transfer and fluid flow FEM model

►Advanced 3D FEM transformer model for the coupled solution of CFD-heat flow equations. ► Integrated tool for transformer thermal simulation. ►No need to predefine convection at the interfaces between the active part and oil. ►Automated design process, increased model accuracy and small computational effort. ►Predict thermal distribution without prior knowledge of thermal nodal properties.
