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.
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.
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.
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.
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.
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.
