Earth grid injection testing
WebFirst, the earth electrode of interest must be disconnected from its connection to the site. Second, the tester is connected to the 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 meters (65 feet) is sufficient. WebEstablishing injection testing traverse locations, this includes: a) A remote current injection point for the testing, placed at a distance far enough away to be considered at remote earth. b) A voltage traverse for measuring …
