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.
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.
The rod is for lacking in bonding to rest of system and was irrelevant. Those assumptions were two hundred fifty feet or so in soil that is between the system and the machine rod that provide the low impedance. The test would show the need of bonding jumpers and other changes.
Several organizations and agencies that issue some guidelines, standards and recommendations for safety testing ground. Whatever one would follow, key components would be the same such as stakes and connections. Those must be carefully be inspected annually for issues that could increase that resistance, static electricity would be building up and without the proper bond, those electricity would discharged.
In attempting in calculation in possible short circuit current on power plants then other current situations or high voltage would determine complex of the grounding impedance really is important since impedance would be madding up the capacitive and inductive elements. Because of resistivity and inductivity are known to be the cases, the actual situation could determine using the complex computation which will be useful for later data computation.
