Avaliação do potencial em solo de duas camadas baseada no modelo do potencial constante.

Abstract

Grounding electrodes and soil models are studied and two of them presented : the constant potential electrode model and the two-layer soil model. The first consider the current in the soil to be non uniform, and the second has a relative simple and is appropriate to the majority of the Brazilian northeast soil. Two routines are implemented. They may be used to assist on the design of substation grounding mashes compatible with industrial needs. Simulations of the grounding systems are performed and the results are in agreement with previous works.
