Right up front, I am requesting that we don't get in to a discussion about ground systems or the technical aspects in this thread please.
The situation: I have a customer who requested that we test their grounding system. When I asked "How?" they sent me a test report from the electrical contractor in another State from another site. I don't know much about grounding, but I do know that doing a 3 point fall of potential test on a 2/0 wire cadwelded to the building and a buried ground ring tells you nothing.
My question: Since I don't believe the average Electrical Engineer know any more about ground rings and ground testing than a good electrician, does anyone know of a reputable contact who can develop a proper yearly testing plan for a site ground system?
One other option I see here is, for one of you who is expert to tell me I am barking up the wrong tree and a physical/visual inspection and a single fall of potential test point at the service is adequate.
