Grounding Resistance Testing Grounding and the Importance of Testing Grounding Grounding resistance testing is very important when grounding, a poor grounding will not only cause unnecessary downtime, but lack of a good grounding is also dangerous and increases the risk of equipment failure. Without an effective grounding system, there is a risk of electric shock, not to mention a range of possible intermittent woes that result from meter errors, harmonic distortion, power factor, and more. If fault currents are not properly designed, effectively maintained grounding systems are directed to ground, the consequences will be difficult to estimate at any time.

Ground Resistance Testing A good ground is not only for safety; it is also used to prevent damage to industrial equipment. A good grounding system will improve the reliability of the equipment and reduce the possibility of damage caused by lightning strikes or fault currents. In our country, tens of billions of electrical fires are lost every year. This does not take into account the associated litigation costs and loss of personal and business productivity.

Ground Resistance Testing Corrosive soils with high moisture content, high salt content, and high temperatures can corrode the ground rod and its connecting tissue over time. Therefore, although the ground system originally installed has a lower ground resistance value, if the ground rod is dried out, the resistance of the ground system will increase. This is why it is strongly recommended that all grounding and grounding connections be checked at least annually as part of a normal predictive maintenance program.

During these periodic inspections, if the measured resistance increases by more than 20%, the technician should investigate the source of the problem and make corrections to reduce the resistance by replacing or adding ground rods to the ground rod.
