WebFeb 9, 2024 · Maintenance Testing – Grid Integrity. Basic testing of the ground mat employs the use of a high current DC power supply (300A continuous rating), calibrated digital voltmeter, and a DC clamp-on ammeter to perform Integrity (Point-to-Point) measurements. Testing can be performed while the substation is energized. 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.
