Webthe earth electrode. Then, for the 3-pole Fall-of-Potential test, two earth stakes are placed in the soil in a direct line – away from the earth electrode. Normally, spacing of 20 m is sufficient. A known current is generated by the Fluke 1625 between the outer stake (auxiliary earth stake) and the earth electrode, Webthe test report. There may be more than one unit in a DB, in such case each needs to be tested accordingly. The unit must sustain a leakage current at 50 % and trip at 100 % of the rated earth leakage tripping current (rated residual current) / an. NOTE This test can be carried out only after power is available at the point of supply.

WebTo measure the soil resistivity start the Fluke 1625 and read the resistance value in ohms. In this case assume the resistance reading is 100 ohms. So, in this case we know: A = 3 meters, and. R = 100 ohms. Then the soil … WebElectrical Grounding. The following papers are being presented in either only PDF format or both HTML and PDF. Some of the papers were only available as hardcopy.
