There are many operations done underground. For instance, you have the pretty common electrical grounding systems, which are utilized by most residential and commercial settings. However, this isnt something that is done without prerequisites. If you want to make it sustainable, then you must conduct an evaluation in the form of 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.
In this procedure, you would need good soil models. It is through that that you can get an accurate basis of testing and develop a good grounding design. When choosing a resistance meter, one should take utmost care and circumspection. That is because the electronics and devices involved are extremely specialized, most especially where signal filtering is concerned.
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.
That should be enough in itself to impress on anyone the indispensability of grounding systems. When it is successfully carried out, evaluated, and accordingly adopted, then that can be the basic potential when choosing other corollaries, from the building structure to the electrical conduits, power supply, instrumentation system, you name it. There are many dependent structures lie, say, stratification, electrode type and size, depth, and the properties of the soil itself.
Grounding is very much imperative because it is what puts a stopper on rogue currents when there are faults in the system. The earth serves well as a conduction path from the power outlet to the transmission facility. Theres a lot of nitty gritty here, such as in making sure that the ground impedance must not go beyond itself, and the same applies to the maximum voltage, which, when it goes overboard, can be quite detrimental to people and other living things.
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.
