Good grounding protects people and equipment, and improves the performance of sensitive electronic equipment. The bonding to the ground system is also a critical part of the system. Testing the quality of grounds and bonding should be an active part of any electrical maintenance strategy. Ground testing is done to determine the effectiveness of the ground system and connections to protect personnel and equipment and ensure optimal equipment performance. Clamp-on ground testing first appeared in the 1980s and has gained in popularity and acceptance in the years since its introduction. This booklet will focus on the clamp-on method of ground testing and is designed to give the reader a better understanding of the test method and where it can and cannot be used. Factors that a technician may want to consider when selecting a clamp-on ground tester will also be addressed.
