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...
This scientific paper presents a survey of soil resistivity changes and the results of grounding resistance measurements. Adequate grounding systems for telecommunications, electronic and electrical equipment, power lines and lightning arresters of steel towers and high buildings are of extreme importance. Good grounding systems safeguard personnel and equipment during fault conditions. They are also...
This scientific paper presents a survey of soil resistivity and how its value varies due to geological and meteorological factors. Soil resistivity is not only a useful measurement that reflects subsurface structure, but also a basic parameter of the design of effective grounding and lightening prevention/protection systems. The most significant variations occur from such parameters of soil resistivity...
