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.

Electrical earthing testing. We are asked frequently – How do you test an Earth in London?
Here’s the scenario. You’re faced with Electrical earthing testing a substation that is located right in the middle of a heavily built-up area. With hard surfaces everywhere together with congested buried infrastructure in every direction.
Any lead deployment is invariably obstructed by something, e.g. roads, cars, walls, buildings, etc. And, assuming the leads can be accommodated. A test is likely to suffer in-ground noise and/or interference from the city’s / town’s infrastructure. Not to mention the curious passers-by: who would like nothing more than to see you struggle for a laugh by stealing your test leads when you’re back is turned.

Electrical Earthing Science…
On a recent generation project, there was a need to connect a partially completed system to the network as part of a staged commissioning. This meant that the full electrical earthing system had not been fully installed. [Read more…] about When Electrical Earthing Science Actually Works
