What are the Common Tests for Grounding Systems?

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 insi...
