Abstract
The electric safety tends to be more important according to electric facilities's increase and its use in these days. This paper analyzes soil resistivity of two areas in the country using CDEGS(Current Distribution, Electromagnetic Interference, Grounding and Soil Structure, Canada). We designed rod and mesh grounding system and made a comparative study of ground resistance, GPR(Main Electrode Potential Rin), step voltage and touch voltage. Then we could analyz only the safety but also economical efficiency in elocution of grounding. As a result of simulation, ground resistance, GPR(Main Electrode Potential Rise), step voltage and touch voltage became higher in proportion to soil resistivity. Therefore we expect to estimate the propriety of grounding system design through accumulation and analysis of data in consideration of characteristics of soil.
