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.

Good grounding systems and proper wiring can help reduce power quality issues and reduce the risk of premature failure of the electrical system. Regular testing of the ground and the connections should be an active part of your preventive maintenance strategy. One of the time-saving and effective methods of testing grounding systems is by using a hand held clamp-on tester. These testers are used on multi-grounded electrical systems without disconnecting the ground.

An electrical ground serve as a return path for electricity and also protects exposed metal parts in an electrical system from having contact with dangerous voltages in case the insulation fails. It is vital for a ground connection to have good contact with the Earth to ensure proper operation. After a while, the earth connection may develop a high resistance with the Earth. This can lead to erratic operation of equipment and an increased electrical risk. Poor ground connection happens when the soil is too dry which makes the ground less conductive, pulled out ground stake or the terminals are corroded. It is important to routinely test the ground connection for problems.

When an earth connection is not properly connected to ground, the electrical system can become unstable or this may cause electrical hazards. To help spot faults in grounding systems, technicians measure the ground resistance. However, you cannot use an ordinary Ohmmeter for this because it will give you false test results. A digital ground resistance meter is the right tool for this application.

Ground connections serve as a return-path and also protect personnel from getting an electrical shock in case the insulator of the device fails. Ground resistance meters measure the resistance of the ground stake and the earth. A good connection should have minimal resistance. Loose connections and dry soil can cause poor contact which gives a high ground resistance reading.
