The project of these transformers is implemented by providing the most severe situations that may be submitted in place intended for installation and should be able to withstand the diverse nature that may be exposed. Despite the extreme care taken in the design phase of these devices, the practice has shown a number of significant failures occur. Among the just causes include mechanical stress or effort observed in the internal structures of the devices due to the additional effort caused by the transient inrush currents. The investigation of these harmful effects caused by the phenomena mentioned thus becomes imperative. From this perspective, this paper aims to describe and analyze the different effects such as tension and compression that is subject to external and internal coil under the action of radial and axial forces involving the coils of the transformer depending on the severity of the disorder, may compromise the physical integrity of the device causing loss of efficiency of the machine or even lead to disuse. Therefore, for this purpose will be used a computer modeling based on finite element method, which allows the simulation of phenomena of transitional and permanent besides enabling access to the quantities in electromechanical transformer windings.Acesso AbertoTransformadores elétricosCorrentes elétricasEsforços mecânicosDeformações e tensõesCNPQ::ENGENHARIAS::ENGENHARIA MECANICAAnálise de esforços mecânicos nos enrolamentos de transformadores ocasionados por correntes de energização utilizando método de elementos finitosTrabalho de Curso - Graduação - Monografia
