Earthing System Design Procedure A Probabilistic Approach

Earthing System Design A Probabilistic Approach

What are the procedures for creating an HV Earthing System Design? Also, how might these differ from an LV Earth design?

Firstly, although the principles underpinning HV and LV earthing are similar, the approaches are very different.

Probabilistic Approach

The first huge difference is the recognition that HV electrical earthing design is probabilistic in nature. Whereas LV earthing is far less so. 

What do I mean?

What is an Earthing System – A Definitive Guide to Earthing, Grounding Systems

Earthing System

In Electrical Engineering terms, earth or, grounding system is the point of reference in an electrical circuit from which the voltages are estimated. The earthing system or to our friends over the pond; grounding system also has the function of providing a common return path for electric current through a physical connection to the geology. In an electrical installation, an earthing system or grounding system electrode connects specific parts of that installation with the Earth’s conductive surface for safety and functional purposes.

Floating Roof Tank Earthing Strategies – Bypass conductors for lightning

Floating Roof Tank Fire

Floating Roof Tank Fires are Common

There are some 15 to 20 known Floating Roof Tank (FRT) fires per year. Floating Roof Tanks are especially vulnerable to the direct and indirect effects of lightning. Direct, or a nearby lightning strike can cause electrical current to flow across the tank shell and roof. When these lightning currents arc across the roof/shell interface, they can ignite any flammable vapours present with devastating effect.

Your Standard Earthing Design – Are They Valid Anymore?

Standard Earthing Design

A number of organisations across the UK recommend a standard earthing design when building smaller scale substations. The key driver behind these is one of cost. Nobody wants to pay more than they have to. For an HV connection using a templated approach to meet Earthing Standards compliance kind of makes sense – or does it?

So, the question is – does installing a standard earthing design meet your obligations under the Electricity at Work regulations?

Avoid Being Caught-out With The Wrong Trousers – Employ a CDEGS Certified User

Wrong Trousers

CDEGS Certified User – The Right Trousers

CDEGS – The Misconception

The term ‘CDEGS’ is loosely banded around a lot in our sector. To deliver safe Electrical Earthing System Design. When carrying out earth potential rise studies.  Therefore, the trouble is there’s a lot of confusion. Also, misinformation surrounding which version of CDEGS should be used. And for what application. As a result, A CDEGS Certified User has no doubt!

Generally, the misconception is that there’s only one CDEGS, wrong!
