In this episode, E&S Grounding Solutions President David Stockin builds upon the previous episode’s discussion on testing the continuity of a grounding system, this time focusing on the clamp-on method. In this method, the clamp-on meter will induce a current on the system in two directions. The clamp-on meter can then determine the resistance. Normally, a low resistance reading will indicate that there is a good continuous loop between the grounded object under test and the larger grounding system. However, in the case of isolated grounds, the desired resistance measurement on the clamp-on meter would be extremely high (open) to indicate that current only traveled successfully in one direction. Then, a two-point test can be used to validate that there is a continuous path for the isolated ground. A clamp-on meter can provide key insights into possible issues such as leakage current and corrosion.
