Isolation transformer simulation in COMSOL.
Two models were created, one 2D Axis-symmetric and one symmetric 3D, the latter is the real representation, but the Axis-symmetric allows a good approach for optimization, reducing time.
Losses in the core due to Facault currents and in the windings due to the Joule effect are analyzed. Stray reactances are also analyzed for analytical comparison and total flux in each domain of the model.
