Electrical Earthing System Design & Soil Resistivity Testing
We take a look at soil resistivity and provide practical advice on what is ground soil resistivity, why we measure it and these common mistakes when Soil Resistivity Testing:
Soil Resistivity Testing Methods a popular post. Originally published in 2013 and now updated.
A Wenner probe test is a geotechnical investigation method used to determine the electrical resistivity of the soil.
Soil resistivity testing can be carried out using different methods. The Wenner 4 Probe test is one of the most common soil resistivity testing methods. Also, its one of the three most popular soil resistivity methods employed, to perform a soil resistivity test. Therefore, this piece describes how to carry out the Wenner 4 Probe Test Method.

This is similar to the Wenner probe test, but it uses multiple current electrodes rather than just two. This allows for a more detailed and accurate measurement of soil resistivity.
Soil resistivity testing carried out using different methods, this is another of the three popular approaches to perform soil resistivity testing:

The Soil resistivity is determined using different Soil Resistivity Testing methods. However the Driven Rod, described below is the last of the three most popular Soil Resistivity Testing methods we use to measure the soil resistivity.

Ian: Hello and welcome.
How many times have we faced with the install team, or you are doing tests on site. You come back, and the readings are high, far higher than expected, and you are scratching your head wondering what is going on.
My name is Ian Griffiths, I am the Principal Consultant here at GreyMatters. In today’s webinar, we will take a step back, and we are going to revisit a webinar that was a piece done by Hugh a couple of years ago now, but it has come up is very topical. It is something that we get asked a lot of questions on. So that is the plan for today, let us dive in.
