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.
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.
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.
This be the most commonly use method for testing in newly installation of grounding systems. The soil got lots of layers that could cause resistance in varying greatly. The soil restively could test with resistance tester. There are lots of other factors which could affect the local resistivity, one should perform the resistivity test a bunch of times, with stakes that laid out on different directions. In ensuring the configuration, one should study those parts and develop the area profile.
