Tips: Why do we need test the grounding system?

Good grounding is not only the guarantee for personal safety, but also to prevent plant and equipment from the damage. A good grounding system will improve the reliability of the equipment and reduce the possibility of damage caused by lightning or fault current.

Over time, high humidity, high salinity, and high temperature will change the properties of the soil, possibly increasing the corrosive proximity of the grounding rod and its connections. Thus, although the grounding system has a very low grounding resistance when initially installed, the resistance of the grounding system increases if the grounding rod is corroded. The ground resistance tester is a necessary troubleshooting tool to help you ensure the normal operation of the system. When a troublesome intermittent electrical fault occurs, the fault may be related to poor grounding or poor power quality. This is why it is strongly recommended that all grounding systems and grounding connections be inspected annually as part of predictive maintenance plans. If the measured resistance increases by more than 20% during regular inspection, the technician shall investigate the cause of the problem and reduce the resistance by replacing the grounding system or adding grounding rods to the grounding system.
