The AEMC 3711 measures ground rod and grid resistance in any environment without the use of auxiliary ground rods. Clamp-on ground resistance testers are used on multi-grounded systems without disconnecting the ground under test. The 3711 simply clamp around the ground conductor or rod and measures the resistance to ground fast and accurately.
By performing measurements on installed ground systems, the user also verifies the quality of the grounding connections and bonds. Resistance and continuity of grounding loops around pads and buildings may also be measured.
The 3711 includes a current measurement function. The probes high sensitivity enables measurement of leakage current flowing to ground or circulating in ground loops down to 1 mA as well as neutral and phase currents to 30 Arms. This feature provides additional information, which is vital in distribution ground networks carrying higher levels of noise and harmonics, that affect power quality.
