Ground System Resistance Testing: Site Compliance Testing
Many equipment manufacturers now require that the grounding system for their equipment must be 5-ohms or less and that resistance-to-ground tests be conducted on the grounding system in order to validate the warrantees on the equipment. The 3-point fall-of-potential method and/or the Clamp-on Induced Frequency Test are used to measure the resistance-to-ground of existing grounding systems.

Resistance-to-ground testing requires highly trained personnel to properly conduct the tests and ensure accurate results. In the past, many of these tests have been found to be invalid due to poorly trained technicians running the tests. Don’t let the warrantees on your equipment become “null and void” due to errors on the part of the people conducting those tests.
