Correlation Analysis between Grounding Resistance and Seasonal Variations of Upper Soil Resistivity of Two-Year Period in Balozhi, Latvia

This scientific paper presents a correlation analysis between grounding resistance and temperature, humidity, pressure, precipitation, snow cover, solar flux by using program STATISTICA 6. We are reporting the results of grounding resistance measurements of two-year period using a 3-point method. The measurements were conducted during selected periods: from March 1 to March 31 in 2010; from July 1 and July 31 in 2010; from October 1 and October 31 in 2010; from January 1 to January 31 in 2011; from March 1 to March 31 in 2011; from July 1 to July 31 in 2011; from October 1 to October 31 in 2011; from January 1 to January 31 in 2012, in Balozhi, Latvia using the 3-point method with ground resistivity tester type M416
