Análise dos métodos de cálculo de resistência e potenciais de aterramentos elétricos

Abstract

This work presents the resistance and grounding potential calculations for homogeneous and heterogeneous soils of two horizontal layers, both of constant resistivity. For any grounding system, conventional methods for these calculations are presented. An alternative calculation method is proposed, which uses a smaller number of equations to solve. The advantages and disadvantages of each method are presented and justified. The physical conceptualization is widely used, taking advantage of the numerical results obtained through the presented methods. For both grounding resistance and ground potential calculations, theoretical-experimental comparisons are made.
