Here is a collection of Soil Resistivity Survey Video(s). Some are from us, the team at Greymatters. And, others sourced from Youtube. Can you spot the real guys?
Here’s Ian of Greymatters (not feeling 100%) carrying out a field soil resistance survey.
What is Soil Resistivity
Soil resistivity is a measure of how much the soil resists the flow of electricity. Therefore, it is a critical factor in the design of systems that rely on passing current through the Earth’s surface. So, an understanding of the soil resistivity and how it varies with depth in the soil is necessary to design the grounding system in an electrical substation, or for lightning conductors. Also, needed for the design of grounding (earthing) electrodes for High-voltage direct current transmission systems. So, in single-wire earth return power transmission systems. The earth itself used as the path of conduction. Hence, from the end customers (the power consumers). And, back to the transmission facility.
Therefore, in general, there is some value above which the impedance of the earth connection must not rise. Also, some maximum step voltage not to exceed to avoid endangering people and livestock.
The soil resistivity value is subject to great variation, due to moisture, temperature and chemical content.
So, here’s a soil resistivity survey video from Autopedia (I think generated from Wikipedia)
Likewise, here’s Ian of Greymatters again Soil Resistivity Testing – In the mud, showing true commitment to the glamorous side of the job. Always, the true professional.
Finally a Soil Resistivity survey video on field testing. Or is the guy using his garden as a demo site?
Note he’s nothing to do with Greymatters Global – We are showing his video to contrast the various styles and methods used in Soil Resistivity survey & testing.
