They say that it is good be grounded. The structures that is properly grounded systems of electric are crucial in case of safety for the equipment and people, it would give current from utility overvoltage or lightning strike. The complex or the simple grounding systems would require the ground testing in ensuring the readiness.
Those that ensure the installation meets the required specification and the people that would make sure it would meet the grounding standards. The electrical system would need low impedance way in grounding for protection of people and the equipment. And the second is because of deteriorate and that it does their performance.
In testing the level grounds in the system, you have to measure its resistance that is between the ground connection and the earth. That would not be straightforward at it looks like. The results would be approximation even though one would be dealing it with the precise measurements. Those variables which affect measurements could and would do in changing the readings.
The driving electrode grounded deeper is very effective path in lowering ground resistance. The soil should not be consistent in resistivity and could unpredictable. Resistance level could generally reduce via additional forty percent and doubling length of the ground electrode, sometimes it is impossible in driving the rods deeper especially in areas that has lots of rock.
The intermittent failures would also create issues from the random shocks on equipment failures which difficult in locating. That equipment is blamed on failure when it really is lacking solid ground. When the random shocks would be experienced in a station shower place, it would be determined in after the extensive testing which portion of building were operating.
The grounding is what should be done when one has to connect the system to the earth. The bonding is connecting the components into grounding system. Both, one would be useless with the other. It means that one could acquire the effective grounding. The absence of it would be lack in effective lower impedance way over that short circuit could flow in ground. That would leave unsafe equipment, enclosures and metal raceway.
Correct equipment and methods should used in producing right data to the system. Clamp on exam or the stake less method would enable the testing in easier and faster way. But it must never be used in measuring the resistance of the soil. That technique is not recommended in complex systems of grounding that has metallic loop.
During last decade, new technology has appeared in market, in form of clamp on tester. That devices were developed for improving the convenience and speed of the exam. Fall in potential exam could labor time and labor intensive consuming. The expedient methods would still require one in straining drive and leads probes. You just have to clamp over ground rod then take the reading. That convenience both be drawback and advantage.
Clamp in tester ground could be indispensable tool. However, its simplicity could also lead in trouble. A lot of end users have tended in clamping around convenient point then take away reading without any question. The outcome is becoming unwelcome in some industry. The user must test the equipment in principle of the operation in where it would not and will work.
