Unlocking the Power of CDEGS: Beyond Earthing Studies

Earthingg Studies done, but what else?

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 […]

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. […]

An EFW Plant Case Study: Examining Low and High Voltage Earthing Protection

High Voltage Earthing Protection – A Case Study at an EFW Plant

In the context of electrical earthing or grounding. Earthing Protection defined as the Protective Earthing of electrical installations at low voltage, i.e. <1,000V AC as described in Electrical Earthing Standards BS 7430. So, in this case, study. We take a look at a few challenges we came across while designing the HV Earthing and Lightning […]

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? […]
