What Is The Acceptable Earth Rod Resistance Value. The data is presented in tabular format,. R = resistance in ω. The simple equation used to calculate the rods bed resistance is given by schwarz [ref. Ieee std.142:1991) enable the resistance to ground to be calculated. The resistance value r read on the ohmmeter can be used to calculate the resistivity by applying the following simplified formula: Length of rod (m) d: Unfortunately, there is not one standard ground resistance threshold recognized by all certifying agencies. Ρ = 2 π a r where ρ is the resistivity in ω.m at the point. Diameter of the rod (mm) a: The acceptable earth resistance value depends on the application,. The measurement of ground resistance for an earth electrode system is very important. It should be done when the electrode is first installed, and then. S = space between ground rods. The nfpa and ieee recommend a ground resistance value of 5 ohms or. Ρ = resistivity in ω.cm.
