High Voltage Earthing & Grounding System Design Protecting Lives

Published 21 Feb 2018


Special Thanks To Ian Griffiths - Earthing System Design HV

In this Guest Blog from Ian Griffiths (GreyMatters Principal Partner) we learn how and why GreyMatters are revolutionising earthing system design and changing the status quo to protect our homes, businesses and industries from the harmful effects of uncontrolled releases of High Voltage HV electrical system power, including lightning strikes.

Below Ian discusses the successes of the last year at GreyMatters.

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 High Voltage Earthing/Grounding Design.

“Saving Lives” Explained

Above is a 2-minute explanation video on how we get to the lives protected numbers.

By-the-way, all rail sector work is ignored as this would add millions to the figures – which is great, but, for the purposes of catching the underlying trend for less populous work, it is not so helpful.

It’s an interesting dilemma, given that personally, my goal is to know that somewhere out there our work in Earthing/Grounding Design, has saved at least one person’s life.

And based on the HSE.gov.uk’s statistics for the UK, the rate of fatal injury per 100,000 workers is at 0.4 (2017); 6% (8) of those who sadly died last year (137) was as a result of electrocution, which means statistically in our population of 498,500 workers, we have still have got work to do! Given, we’ve influenced just under 1/8 of a worker’s life during 2017, we need to reach a figure closer to 4.16m workers to claim our first life saved.

Cumulatively, since we’ve been recording lives-protected, GreyMatters has recorded 1.4m which equates to a little over 1/3 of a life saved (statistically speaking of course).

Without wanting to sound too GreyMatters-centric – we upgraded the business systems to full UKAS accreditation for ISO9001, 14001 and OHSAS 18001. This is pretty unique as it makes GreyMatters the only independent specialist Earthing/Grounding Design Consultancy to be fully UKAS accredited – part of being a Top 1% specialist consultancy.
