Typical Ground Resistance Values at Joyce Cope blog

Typical Ground Resistance Values. resistivity varies from less than 1 ω.m for sea water up to 109 ω.m for sandstone. Electrode resistance and resistance of its connection. But, there are four variables that. This paper captures the fundamental principles of ground electrode design, ground resistance and soil resistivity. the nfpa and ieee recommend a ground resistance value of 5 ohms or less while the nec has stated to “ make sure that system impedance to ground is less. the resistance between a grounding electrode and the earth is generally known as ground resistance. Resistivity varies not only with the type of soil but also with temperature, moisture,. in the case of grounding resistance, we will be dealing with known values for soil resistivity, rod diameter and desired system ground resistance. grounding resistance is comprised of the following elements:
