Abstract: This paper presents a thermal models to simulate a thermal behaviour of different type of transformers. Heat disipated is always problem in transformers, esspecialy in large power transformers. Coupled physical and mathematical models would assist in the development of a system that was both accurate and simple to implement. Material proporties, the geometry of the model, heat transfer coefficients for each surfaces are introduced as the input values. For the accurate results of the temperature distributions, the exact values of heat transfer coefficients are required. However this can be managed by solving the flow field equation by using any means, i.e. numerical methods, analytical methods. The performances of the models are compared to the analytically determined performance of transformer or to the experimentally determined performance of transformer and the results obtained are in a good enough agreement with open literature. The thermal models based on fini!
te element analysis are shown to be more accurate then the model based on equivalent electrical circuit. Finite element software, as CAD tool or other application modes for fundamental physics provide several benefits: reduction of the costs for designing a new device, reduction of number of prototype, reduction of price, simplification of the manufacturing process, increase technical performance, ….
