Abstract

The purpose of this study is to validate an already designed three phase power transformer with some advanced ANSYS modules, such ANSYS Maxwell 2D and ANSYS Mechanical, for three types of charging (minus tap position - rated parameters, medium tap position - 50% and maxim tap position - 100%). On the same time, it can be seen the 2D magnetic nonlinear behaviour of this three phase power transformer and thermal effects for the ferromagnetic core. Also it can be found the magnitude of B field, the regions with problems and the value of the total core losses for the same transformer. It has used the latest versions from ANSYS, Workbench 14.5, ANSYS Mechanical and Maxwell 2D v.16.
