Think anything like grounding as foundation of house that would hold all the electrical system. Without that, whole thing would come tumbling down. The ground testing could fall in two categories and that is one that ensure the installation shall meet the ground specifications and those that make sure that it would meet the specification.
Grounding path would provide low resistance way for the travel of electricity. The electrical power should travel from source throughout load then return to source through neutral connection. That connection would offer secondary path in safety. Those return paths should provide least resistance at current.
Grounding encompasses in two different objective the equipment and earth grounding. The earth grounding is intentional connection that comes from circuit conductor to grounds electrode in earth. The equipment would ensure which operating mechanism in structure be grounded properly.
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.
Fall potential of test method used in measuring ability of earth system in grounding or individual electrode in dissipate energy from site. Land electrode in interest should be disconnected. Tester then connected to earth electrode. Two earth rods are then placed in soil in very direct line mostly away from electrode for three poles of potential testing. The spacing of twenty meters normally be enough.
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.
