About This Episode
In this episode, E&S Grounding Solutions President David Stockin chats about three tests commonly used to test a grounding system. A four-point test reveals properties about the soil surrounding the grounding system. A three-point test can be used to measure the resistance from one or more metal electrodes to the earth. A two-point test helps to confirm that an electrically continuous (very low impedance) path exists throughout the grounding system. The results of each test offer key insights into assessing the performance and safety of a grounding system.
