Importance of Soil Resistivity Testing for 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 […]

5 Reasons Why Hot-Sites Aren’t Dangerous: Myth Busted

hot site

What is ‘HOT-ZONE’ or ‘Hot-Site’? There are so many misconceptions surrounding the whole concept of a‘Hot-Site’ and ‘Hot-Zoning’ for Electrical Earthing Designs.  In this article, I attempt to simplify what ‘Hot Zone’ (or Hot Site) means in Power System terms AND crucially, explain what a ‘Hot Zone’ is not. By the end of this article, […]

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 […]
