Why Greymatters Consultants Use CDGEGS HIFREQ Earth Modelling Software

Soil Resistivity Testing

Clients 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.

Soil Resistivity Testing in the Wet – Ninja Tricks to Help You Spot the Enemy

Soil Resistivity Testing

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.

What is Soil Resistivity Testing & Why is it Important to Safe Electrical Earthing Design

What is Soil Resistivity Testing

What is Soil Resistivity?

Soil resistivity is a measure of how much the soil resists the flow of electricity. Soil Resistivity Testing is determining that measure. Therefore, is a critical factor in the 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 systems. In an electrical substation, or for lightning conductors. Also for the design of earthing electrodes for substations and high-voltage direct current transmission systems needs this measurement. Because most substations, use the earth to conduct all or, a significant portion of fault current when there are earthing faults on the system.

Electrical Earthing System Design Separation

Soil Resistivity Separation of Earths in Earthing Grounding Design

During a recent training event held by SES Technologies for CDEGS (Current Distribution, Electromagnetic Fields, Grounding and Soil Structure Analysis). A finite element analysis software suite for Electrical Earthing System Design, a number of issues were discussed. But one that crops up time and time again in the UK was that old chestnut in Electrical Earthing System Design Separation.

7 Deadly Sins … of Electrical Earthing … Part 3

7-deadly-sins-of-earthing

In our previous post, 7 Deadly Sins of Electrical Earthing… Part 2, we continued the 7 deadly sins of earthing/grounding, up to and including Sin # 5.  We now conclude with sins 6 – 7. [Read more…] about 7 Deadly Sins … of Electrical Earthing … Part 3
