Electrical Earthing System Design & Soil Resistivity Testing
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.
[Read more…] about Soil Resistivity Testing Method – Driven RodClients often ask us why we use CDEGS HIFREQ instead of XGSLab or, any of the other packages available in the market. And our usual response is simply. “It’s the market leading product (Top 1%)”. So, I thought it might be useful to quantify exactly why it is the leading product and also why it commands a leading price. In addition, to demonstrate how some of the less capable products leave you and your staff exposed to unquantified risks.

This is a series of short posts on Soil Resistivity Testing. And the common mistakes encountered, with practical advice on how to avoid common mistakes. Part 10 – Soil Resistivity Testing Erratic Readings.
So, when carrying out soil resistivity testing. Erratic readings can occur due to poor connections. Also, through high contact resistance. And background noise at a frequency similar to that used by the measurement equipment. Nearby buried metallic structures, equipment failure, operator error, and other factors.

Soil Resistivity Testing Background Noise – Due to nearby sources of 50 Hz (or 60 Hz) current and its harmonics, electrical noise at these frequencies is expected in the measurements, particularly for the larger electrode spacings. [Read more…] about Soil Resistivity Testing Background Noise

A Soil Resistivity Testing weak signal can result from a low-power source, a low-voltage source, or a high contact resistance of one or both of the current injection electrodes. [Read more…] about Soil Resistivity Testing Weak Signal
