Calculation of Magnetic Fields Generated by Traction Transformers and Busbars in Electric Locomotive Systems by Finite Element Method

The effects of the magnetic field intensity created around power system equipment on human health are examined by various organizations. Permissible limit values have been determined International Commission Non-Ionizing Radiation Protection (ICNIRP) when people exposed to generated at a low frequency. Accordingly, maximum allowable for public areas and working environments specified as 0.2mT 1mT, respectively. In this context, it is seen that components such traction transformer, busbar, driver, motor used provide in locomotives essential parameters. Therefore, recommended intensities these remain below limits passengers personnel. For reason, necessary determine during design phase locomotive systems. This study aimed calculate densities transformer sample busbar structure locomotives. purpose, geometric model simple casing, was three-dimensional coordinate transferred Ansys Electronics Suite finite element analysis software, studies were carried out. Finally, measurement planes according results values. Since change depending model, material parameters, operational status, necessity evaluating analyses stage has emphasized within scope study.
