The measurement of the loop resistance is relatively close to the resistance of the ground electrode being tested. If there were 60 similar ground electrodes with a resistance of 10 Ω each, the measurement of the total loop resistance would be: Rloop = 10 Ω + 0.17 Ω = 10.17 Ω.
WebThe clamp-on methodology is based on Ohm’s Law (R=V/I). A known voltage is applied to a complete circuit and the resulting current flow is measured. The resistance of the circuit … WebAug 31, 2024 · The 25-amp test requires that the impedance be less than 0.1 ohm at the end of the test period. The 30-amp test requires that the voltage drop across the grounding circuit be less than 4 volts at the end of the test period (less than 0.13 ohm). (A derivation of the grounding impedance limit value, 0.1 ohm, is presented in Technically Speaking ...
