Electrical Earthing System Design & Soil Resistivity Testing
Here is a collection of Soil Resistivity 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 resistivity survey. [Read more…] about Soil Resistivity & Soil Resistivity Testing Methods – A few short Videos
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?
Soil Resistivity Testing in the wet particularly saturated ground. Has the potential for many problems.
Here are some ninja tricks to help you spot the enemy lurking in the damp…
Soil Resistivity Testing is the absolute starting point for pretty much everything to do with design for Earthing, grounding and lightning protection. (click link to flow chart) This is chiefly because all these type of systems are connected to earth and rely on the quality of this interface. Therefore, understanding the soil resistivity and what the representative ‘Soil Model’ will look like is without doubt the single most important foundation to all subsequent safety calculations.

Soil resistivity is a measure of how much the soil resists the flow of electricity. It is a critical factor in design of systems that rely on passing current through the Earth’s surface. An understanding of the soil resistivity and how it varies with depth in the soil is necessary to design the electrical earthing system in an electrical substation, or for lightning conductors.
