The thermal performance of transformers is an essential criterion for their
optimal design and operation and it is of paramount importance to evaluate
the temperatures reached by the transformer core and its windings during
the design process.
Currently, at HPE, a split-core transformer for a particle accelerator is under
investigation as shown on the left of the figure above. This transformer
experiences pulses with a length of 5 μs and a nominal voltage of 700 kV
at the high voltage side. For the design of such transformers, optimisation
procedures are developed at HPE. In order to take into consideration the
thermal aspects inside the optimisation procedures, a fast and accurate
analytical thermal model is required. Hence, in this project, you will develop
an analytical thermal model of such a transformer. In a next step,
you will verify the analytical model with 2D/3D FEM simulations. Already
developed basic models will be provided as a starting point.
