In the present work, the zero sequence impedance, of a three column core type grounding Zig-Zag transformer of 9.959 MVA , 34.5 kV is calculated applying the finite element method. A magneto-dynamic analysis is performed to study the grounding transformer in the frequency domain. 2D and 3D models are built, which are solved through the formulations of vector and scalar potentials. Once the behavior of the magnetic field has been studied, the magnetic energy storage technique is used to calculate the value of the zero sequence impedance. The results obtained by the finite element method were experimentally validated in the laboratory. In recent years the classical design of these grounding transformers has not changed. Therefore, this work presents the solution of a problem posed by a Mexican manufacturer of transformers, which represents an excellent relationship between the university-company binomial.
