WebIn contrast, the moderate-resistivity samples (40–100 Ω-m) had moisture content values of 36.67–56.33% by weight but had higher resistive material fractions of 47.77–60.20%. These moderate-resistivity samples represent wet, resistive materials, in agreement with the findings of Balia (2024). WebBecause soil resistivity is influenced by a variety of factors, such as moisture content, electrolyte content, and temperature, resistivity measurements are an essential step in the construction of any grounding electrode. To accurately calculate soil resistivity, ATS employs the Wenner four-pin method according to ASTM G57.
