Soil Resistivity Testing Method – The Wenner 4 Probe Test

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.

Soil Resistivity Testing Method -The Schlumberger Array

The Schlumberger array is a geotechnical investigation method which determines the electrical resistivity of the soil. 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:

Soil Resistivity Testing Method – Driven Rod

The driven rod test is a geotechnical investigation method which determines the resistance of soil to the penetration of a rod or other penetrometer. 

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.

An EFW Plant Case Study: Examining Low and High Voltage Earthing Protection

In the context of electrical earthing or grounding. Earthing Protection defined as the Protective Earthing of electrical installations at low voltage, i.e. <1,000V AC as described in Electrical Earthing Standards BS 7430.

So, in this case, study. We take a look at a few challenges we came across while designing the HV Earthing and Lightning Protection Systems. For a 9MW Energy from Waste Plant in Europe.

Earthing Calculations for Safe System Design

Earthing Calculations regarding your safety – you’re overdue an update!

If 1-ohm is still in circulation on your documentation then this section applies to you.

Even though the Earthing Calculations for determining a safe System Earth (Ground) has shifted away from an arbitrary resistance figure, usually <1 ohm.  It’s still all too common to see this outdated measure of installed success appear on client/employer requirement specifications(ER’s). As part of the Earthing Calculations Design Safety brief.
