Grounding is important to do where electrical systems are utilized. However, one would have to take into account certain qualities and characters of the soil in which this procedure is done on. This assessment is called soil resistivity testing.
There are many methods employed in this regard. However, the considerations to take to account are pretty much the same. You should take into account cases of variability since soil is electrolytic and it can be easily influenced by many given factors. Therefore, conduction properties can really change on a whim.
Among others, you should take a good look at the soils moisture content, which can be a no brainer. And then you have the temperature, especially when above the centigrade freezing point. You have salt content to consider as well. The nub of the matter is that resistivity is not a quality that you can pin down. It is variable and changing, depending on circumstances that may not even be obvious off the bat.
There are certain standards on which you can base on, such as that of the IEC or the International Electrotechnical Commission. They require that seasonal variations be taken to account in all system design transmissions. For example, depending on the season like, say, when the temperatures are very cold, then resistivity can increase by an order of magnitude.
When you do away with resistivity tests, the resultant grounding will most likely be poor, and that can bring a lot of adverse developments down its wake. You have a waste of resources, effort, plus increased downtime. However, the greatest at stake here is your safety, since it can be dangerous to persons and other living things. If you want to think along the business line, then suffice it to say that it can surely result in equipment failure.
Soil resistivity is important to gauge. It is an evaluation regarding the soils ability to resist electrical flow. Needless to say, this is critical, and in fact definitive, in system designs that work to vamp up current passages. Therefore, its critical to have an understanding of what contributes to resistivity and how it is influenced by sundry factors, like soil depth and some such.
The applications are also many and sundry. Or instance, the information collated can be used in designing ground systems, electrical substations, lighting conductors, transmission systems, earth electrodes, and the measurement of moisture content. Some of these applications may sound too highfalutin for common use. However, it stands to reason that they are very much useful to the human enterprise, with uses in wiring systems and even agriculture.
This endeavor can be hard because there are lots of factors to toggle and juggle together. We have mentioned composition, temperature, moisture, et cetera, et cetera. And then theres the collation of factors. After all, nothing about this whole enterprise is homogeneous. You might think that you have the properties of soil down pat, but even with the alteration of an iota, the values can be greatly changed already. There is seasonal variability to take into account, plus the water table.
Some technicians proffer that for everything to be more stable, then the soil should be placed at significantly deeper strata, since factors like temperature and moisture are nearly fixed therein. When the ground rods are installed therein, you might be assured of greater sustainability and maintenance. As they say, for the system to be really effective, then you must design with the worse conditions in mind.
