Resumen:
An efficient modelling of thermal-electrical problems, like in distribution transformers, re-quires complex multiphysics numerical analysis. The analysis can be done using one dedicated tool(software) with coupled multiphysics modelling, including the determination of power losses, heat gen-eration, temperature conduction and convection and the fluid dynamics. Another possibility is to usetwo different tools, each one of them dedicated to solve the specific physics. In the following paper theelectromagnetic simulation is taking place in Ansys EM solver and for CFD modeling Code_Saturneis used. The electromagnetic fields are calculated using transient simulation where the average powerlosses of the transformer are transferred after reaching quasi-steady state in order to reduce computationtime. A coupled thermal-electrical numerical analysis for a distribution transformer is carried out usingtwo separate tools with a interface created for this purpose. The thermal and electrical characteristics areanalyzed and discussed in the paper.
