Get Grounded: Introducing ‘How-To’ Sessions in Earthing Design

How-to sessions in earthing design

If you’re an electrical engineer, you know how crucial it is to have a solid grounding system for your electrical installations. Proper earthing design protects against electrical shock, ensures electrical safety, and prolongs the lifespan of your equipment. But what happens when you encounter a complex grounding challenge that’s beyond your expertise? That’s where “how-to” sessions in earthing design come in.

Our how-to sessions provide a step-by-step approach to solving a specific problem or achieving a specific goal. In earthing design, how-to sessions provide a practical approach to complex grounding challenges. Enabling you to acquire new knowledge, improve your skills, and stay up-to-date with industry best practices.

Soil Resistivity Testing – Common Mistakes

Ian getting ready

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:

  1. Surface Layer Resolution
  2. Buried Interference
  3. Weak Signal
  4. Background Noise
  5. Erratic Readings

Soil Resistivity Testing Method – The Wenner 4 Probe Test

Soil Resistivity Testing Methods 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

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

Driven Rod Method

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.
