WebFeb 6, 2024 · R loop = 10 + 2. Rloop = 12 Ω. 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.
WebAny loop test is measuring the small difference in voltage between a loaded and un-loaded condition. The loop test can be susceptible to errors from; 1, Changes in the load or switching on the supply This can influence supply voltage during the test sequence. 2, Supply harmonics These can affect general performance.
