Avaliação do desempenho do sistema de aterramento de uma subestação (SE) em diferentes tipos de resistividade de solo.

Abstract

This report presents reviews of grounding systems in different configurations soil. The simulations were performed in the environment TecAtPlus 5.2, verifying the potential step and touch the surface of the same against a short-circuit situation. It was also shown improvements in grounding systems to reduce its strength and potential in it. With the results obtained by the simulation concluded that the same grounding system in different types of soil configuration, is not suitable to Brazilian standards.
