Electrical Earthing System Design & Soil Resistivity Testing
Here’s the 30-min webinar on Soil Resistivity Testing
What you’ll get from this is:
Who is this for?
Anyone who is responsible for carrying out or coordinating Soil Resistivity testing
Soil Resistivity Testing Methods a popular post. Originally published in 2013 and now updated in 2020.
Wenner 4 Probe test is one of the most common soil resistivity testing methods. It is also part 3 in a series of short posts on Soil Resistivity Testing Methods. Part 1 & Part 3. Together with, the common mistakes encountered. And also, practical advice on how to avoid the Soil Resistivity Testing 10 Common Mistakes.
So soil resistivity testing can be carried out using different methods. Therefore, below describes the Wenner 4 Probe Test Method. Also, its one of the three most popular soil resistivity methods employed, to perform a soil resistivity test:

Here’s Ian of Greymatters (not feeling 100%) carrying out a field soil resistance survey.
Understanding Soil Resistivity is critical to Electrical Earthing System Design.
Soil resistivity is a measure of how much the soil resists the flow of electricity. So an understanding of the soil resistivity and how it varies with depth in the soil is necessary to design the grounding – earthing system in an electrical installation.

Before installing an electrical earthing system design, there are a couple of other essential tasks to tackle. One of these tasks is the ‘Soil Resistivity Desktop Study.’ This study illustrated in the Soil Resistivity Table below.
Historically installation companies may have offered to drive a single earth rod into the ground and take a range of readings from it at various depths as it is driven deeper. This approached is now considered totally unacceptable for anything other than the most basic of designs, e.g. a generator earth. [Read more…] about What Exactly is a Soil Resistivity Desktop Study?
