About This Episode
In this episode, E&S Grounding Solutions President David Stockin sits down to chat about the three-point fall-of-potential method for conducting a resistance to ground measurement. In this method, there is a particular location for a potential probe that will help produce a reasonably accurate result for the test. However, it is important to take readings at multiple locations to see if there are any problems with the test setup and site conditions. The fall-of-potential method has limitations to its applications because site conditions may not accommodate a good test setup. Still, engineers should learn how the concepts behind the fall-of-potential method can be useful when assessing the design or performance of a grounding system.
