The Telaris Earth-Test can test the ability of soil and grounding connection to conduct electricity and provide an electrical reference point. Good soil conductivity is needed to limit static electricity charge in potentially flammable situations and minimize the voltage difference between power return and earth ground for personal safety. Resistance testing is done by 2 wire, 3 wire or 4 wire testing methods. |
