Electrical Earthing System Design & Soil Resistivity Testing
Ground testing is typically performed in two stages. The first is conducted during the construction of a building to ensure proper installation of the electrical system and the second stage involves routine ground testing to ensure the ‘actual’ arrangements perform as the ‘predicted’ ones at design stage to avoid costly and fatal errors.

Ever been caught in a project meeting and started to think -“what am I doing here?… I hope he/she doesn’t ask me a question. I wish I had found that training course in earthing!“
It’s a disconcerting feeling being ‘out of your depth’ or not even in the right ballpark. How are you going to save face?… I know, nod a few times in the right places and maybe ask an open question back, or better still, side-swipe it to a colleague; “what do you think, Stan?” – then run away and hope no-one notices. Did it work? Yes, phew! Great save… [Read more…] about Avoid death by PowerPoint | earthing system design demystified
Awareness of step and touch potential, caused by a rise of earth potential, is essential for anyone working on high-voltage power transmission and distribution systems above 1 kV.
A rise of earth potential is caused by electrical faults that occur at electrical substations, power plants, or high-voltage transmission lines. [Read more…] about Rise of Earth Potential (RoEP) | Know the Risks
We like to think electricity has been around for years, right? It certainly ‘feels’ like we should know all there is to know. But as an earthing designer. The scientific community tells us we humans are not good at time perspective that falls outside our immediate field of vision. No surprises here. But, [Read more…] about Putting electricity in perspective – a view from an earthing designer
Well, 2017 was an exciting year for the team GreyMatters. So, at the end of 2016, we set goals on what we wanted to achieve in 2017. The biggest success story which is probably closest to my heart is smashing the previous year’s lives-protected by HV Earthing/Grounding Design.
