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.

The Finite Element Method is a well-known technique, being extensively applied in different areas. Studies using the Finite Element Method (FEM) are targeted to improve cardiac ablation procedures. For such simulations, the finite element meshes should consider the size and histological features of the target structures. However, it is possible to verify that some methods or tools used to generate meshes of human body structures are still limited, due to nondetailed models, nontrivial preprocessing, or mainly limitation in the use condition. In this paper, alternatives are demonstrated to solid modeling and automatic generation of highly refined tetrahedral meshes, with quality compatible with other studies focused on mesh generation. The innovations presented here are strategies to integrate Open Source Software (OSS). The chosen techniques and strategies are presented and discussed, considering cardiac structures as a first application context.
