Simulação de um quadro de Epstein empregando o método de elementos finitos

Abstract

The increasing consumption of electric energy leads to the need to increase its generation, which implies concerns about impacts on the environment. Renewable energies are ways to get around these facts. However, there is concern about the efficiency of the equipment used in the transportation and distribution of electricity to consumers, as is the case of transformers. The losses in the distribution of the Brazilian electrical system correspond to 70 %, of these, 33.3 % are losses in the transformer core. In this way, studies to increase the efficiency of transformers are necessary. In this work, a study was carried out on the Epstein Board, an equipment used to obtain the magnetic losses of a ferromagnetic material, for example the materials used in the core of the electric transformers. The study was carried out by means of computational tests and simulations using the Finite Element Method.
