How do I know my 1950’s earthing arrangements are still keeping my workforce safe?

Are Vintage Earthing Arrangements Safe?

I thought I’d continue from my last blog piece talking about heavy current injection earth testing. By talking about a key application where it can potentially deliver much better results than the modern CDEGS approach. Therefore, on your earthing arrangements.

Many industrial sites built in the 1950s and 60s as industrialisation grew. This, in line with the expansion of the electrical grid. Led to a huge program of electrical substation construction around the world. What this means is that some of us own the responsibility of managing sites with ageing transformers, assets and equipment. Thus the design to obsolete standards? Therefore to know what hazard this presents today, is simply unknown.

November 2018 – Earthing Standards update (Rail)

earthing standards update for rail

Earthing Standards Update. For the past few years. 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).

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?

What is Standard BS7430

Ian on-site working to Earthing Standard bs7430

BS7430 2015 is the latest amendment to the code of practice for protective earthing of electrical installations.

BS7430 Overview

This standard is an amendment to BS7430 2011 the code of practice for protective earthing of electrical installations. It provides recommendations and guidance on meeting the requirements for earthing land-based electrical installations in and around buildings in the UK.
