Electrical Earthing System Design & Soil Resistivity Testing
Earthing/grounding design is a safety-critical component of the HV power system. It is often one of the most misunderstood topics or specialisms. In this series, “Earthing Design”, we take the lid off the design process from start to finish, to demystify and bust a few of the common myths and misconceptions.

I have a confession to make…
Earlier this year I found myself in the Southern Ocean at 45deg Lattitude barrelling along at 20-30 knots on a 70 foot (23m) surfboard otherwise known as a sailboat called Black Betty in 45kts winds and 10-12m swells. In those conditions, it’s all one can do, but to think about the here and immediate ‘now’. But, outside the times of sheer panic, and during the time of reflection, the thoughts of superpowers surfaces.

Also, the reasons to invest in the top 1% of tools, knowledge and consultants. But once you’ve invested in building the model to understand what earthing is required, what are the other things you can do with this model. Additionally, answer other questions you might have?

Therefore, in all of these examples, we have completed and verified the earthing design for these sites and found good agreement between the modelled results and the post-installation measurements. On this basis, we can say that XGSLab matches CDEGS for accuracy, and both tools have good agreement with the real-world measurements.
[Read more…] about Comparison between XGSLab and CDEGSSo, the question I poised “Why XGSLab Software And Not CDEGS” And Why Now? Well, that’s a big question and an even bigger decision. In this post, I explain the logic of my decision and the “why” of my decision.
Since 2013, Greymatters prime purpose is to protect life. More personally, my goal is explicitly to save at least one life before I head off to the pearly gates and return into space dust.
Knowing we’re focused on saving lives through the work we do. It makes sense that everything we do supports this goal, i.e. using the top 1% software tools, with top 1% equipment by top 1% engineering talent. So that mistakes are avoided, errors eliminated, and the best chance of surviving electrocution is built-in to all our work.
