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.
It really is recommended that the ground and ground connections should be checked annually as part of normal predictive plan. There should increase in resistance at more than twenty percent in measured during the periodic test, technician must investigate source of problem then make corrections to lower resistance via adding or replacing rods to ground system.
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.
Using variety of ground electrodes would provide another path in lowering the ground resistance. In more than electrode would driven in ground and then connected on parallel in lowering resistance. Additional electrodes in effectivity, spacing of the additional steel should least equal in depth of driven rod. Then increasing diameter of ground electrode very effect lowering resistance. You would double diameter of ground electrode and the resistance could decrease in ten percent.
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.
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.
