MÉTODO DE ESTRATIFICAÇÃO DE SOLO: DIMENSIONAMENTO DA MALHA DE ATERRAMENTO

Abstract

The present study addresses the process of proper design for electrical grounding systems, which are essential to ensure user safety and equipment protection against electrical shocks and failures caused by atmospheric discharges. The Wenner method was used to evaluate the apparent soil resistivity in an area near the laboratory of an educational institution located in Trindade-GO, Brazil. Measurements were performed with varying rod spacings, and the collected data were analyzed through a well-structured 12-step process. The results revealed a significant variation in soil resistivity depending on the spacing, underscoring the need for adjustments in the number and arrangement of rods to ensure the efficiency of the grounding system. The analysis also highlighted the importance of excluding data with high deviations from the mean to improve calculation accuracy. It was concluded that the proper design of the grounding mesh, considering soil stratification and resistivity, is critical to ensuring the safety and reliability of electrical systems. This study reinforces the importance of rigorous methodologies in the planning of grounding systems, contributing to safer and more efficient practices in electrical engineering.
