Electrical Earthing System Design & Soil Resistivity Testing
Firstly I’d like to take this opportunity to wish our Clients, friends, students and Blog subscribers SEASONAL GREETINGS and a very prosperous New Year.
I’m actually in Gibraltar writing this post completing a personal goal of mine. That’s topping up my sailing qualifications in preparation for my exciting challenge later next year to the Southern Ocean competing in the Clipper Round the World Race (more on that next year).

GreyMatters has been fortunate enough to support the rail electrification and upgrade programmes across the UK for Earthing Design. And maintaining a consistent approach. Across a building programme of this scale. Can be a massive engineering headache for all design teams concerned.
Especially, when Earthing Standards touches on so many disciplines along the way. From civils, OLE (Overhead line equipment), signals, EMC, 3rd parties, ecologies, geophysical. As well as the more obvious general E&B (earthing and bonding).

These are great questions and often asked. This post answers these questions together with the choice of conductor materials and jointing method within a high voltage earthing design project.
Assessing conductor size is entirely dependent on the electrical configuration and the load that the conductor must take. For example, an above-ground bonding conductor serves to transfer current with minimal voltage drop, from A to B. A directly buried conductor has an additional purpose, that of leaking the fault current or voltage into the local geology (as part of an electrode).

Also, we’re asked quite a bit about earthing and bonding in general. So, there’s an unusually large amount of confusion around the term Earthing and Bonding. Or, for our friends in the states; you might come across the term grounding and bonding.
Therefore, in this piece, I aim to clarify the difference between – what is Earthing and what is bonding and whether there is a difference.
Breaking things down into simple terms; Earthing – grounding can mean all things to all people. Hence, it is more realistic to think of Earthing as the ‘electrode’ itself. Also, known as the Earth Termination. This reference refers to the physical hardware, such as the copper conductors, rods, etc., that sits buried directly in the geology itself.

I don’t care how many tips and fixes there are out there on the info-web that claim to make boring training for earthing PowerPoint (PPT) slides less boring… THEY ARE STILL BORING!
But here’s the good news.
