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.
Having nothing solidly system could result in loss in expensive equipment, the human lives and even the critical data. That equipment without the adequate grounding would experience the damaging voltage surges or spikes. Loss in ground would cause some sensitive equipment process that incorrectly or losing data.
One could have several methods in doing it. And all of those used least of two reference in current source and ground points. Testing device would circulate the current throughout ground for test. Those testers that was used bridge method is common. The use currents on order in milliamps. And some in high end that use over one hundred a.
The simple systems in grounding that is consist of single electrode driven in ground. Use of single electrode is most common style of grounding. The complex systems of grounding would consist of variety grounds rods, mesh, grid networks, ground loops and ground plates.
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.
