WebJul 8, 2024 · When performing a test, ideally, you would like to see a resistance as close to zero as possible, since the efficiency of a grounding electrode is inversely proportional to the resistivity of the earth. The secret is in the soil (not the sauce, sorry). The soil is what makes or breaks a ground connection. When fault current travels through an ...

I. f the probes sit in a saturated layer of soil. The returning electrons will prefer to travel along the saturated layer or finite volume of soil instead of penetrating the ‘soil’. WebStakeless Measurement. The Fluke 1625 earth ground tester is able to measure earth ground loop resistances for multi-grounded systems using only current clamps. This test technique eliminates the dangerous, and time consuming activity of disconnecting parallel grounds, as well as the process of finding suitable locations. Grounding. sawyer robot youtube
