Abstract |
The measurement of ground resistance is significantly affected by environmental conditions such as temperature, humidity, and structure of the ground that acting as an error in the ground system design and measurement value. In particular, changes in land resistivity due to seasonal fluctuations cause many changes at the time of design and measurement. This paper proposes a method for setting correction coefficients to reduce ground resistance measurement errors. First of all, in order to improve measurement errors, annual earth resistivity was measured by monthly and seasonal. The measurement results was analyzed and correction coefficients were derived using Group Statistics Technique. The results of this study are expected to solve the problem of changes in ground resistivity with seasonal ground resistance. |
