Understanding the risks of EMF

Impressed voltages and interference from electromagnetic fields are increasingly becoming a hot topic for safety professionals and engineers alike. Hugh looks at understanding the risks of EMFs, when you need to do an EMF study and how XGSLab does the heavy lifting for you when doing EMF studies. Watch a replay of the webinar here.

Ian: Hello, and welcome.

Thank you all for coming here today. For those of you who don’t know me, my name is Ian Griffiths from GreyMatters, I am the principal consultant here. And I’d like to start things off with a quote or something that kind of resonated through the past week. One that came to mind was this, it was beautifully done. “Nearly everything awesome, takes longer than you think, get started now and don’t worry about the clock.” Think that’s a massive mantra to live by.

Why is a hot site a problem?

Hugh takes us on a deeper dive into hot sites and answers the question ‘Why is a hot site a problem?’ You can find the webinar replay here.

Hugh: Hello, everyone, thanks for joining our webinar this morning. This is a continuation from our previous session where Ian introduced the concept of a hot site and talked about how it came about. You can find a replay of the first webinar ‘Why am I getting a hot site?’ here.

And what we are going to do in today’s session is we are going to develop on from that and talk about what the problems associated with hot sites are. Talk a bit about some of the things you can do to fix hot sites when they come about as a problem.

CDEGS – Not Only Earthing Studies. Other things you never realised YOU could do!

We’ve written previously about why we use CDEGS HIFREQ and (X)GSA_FD for earthing studies. Also, the reasons to invest in the top 1% of tools, knowledge and consultants. But once you’ve invested in building the model to understand what earthing is required, what are the other things you can do with this model. Additionally, answer other questions you might have?

Comparison between XGSLab and CDEGS

In this blog, I’m going under to hood, so to speak. Comparing CDEGS with XGSLab to show you some real-world examples where CDEGS and XGSLab give almost identical results.

Therefore, in all of these examples, we have completed and verified the earthing design for these sites and found good agreement between the modelled results and the post-installation measurements. On this basis, we can say that XGSLab matches CDEGS for accuracy, and both tools have good agreement with the real-world measurements.

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