Measuring ground resistivity is a method of assessing the condition of grounding systems. Ideally, the ground rod should have a low resistance path with the soil. However, when the soil loses moisture or the ground connection is faulty, the resistance may increase and impair the ground’s effectiveness. Bad ground connections can cause erratic operation of equipment and serious damage to the electrical system.
Megger offers a line of ground testers that can help with maintenance and troubleshooting. The Megger DET family of ground testers offers a comprehensive testing solution for ground rod and soil resistivity diagnostics.
