Low Voltage & 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 Protection Systems. For a 9MW Energy from Waste Plant in Europe.

Earthing Calculations for Safe Earthing System Design

Earthing Calculations regarding your safety – you’re overdue an update!

If 1-ohm is still in circulation on your documentation then this section applies to you.

Even though the Earthing Calculations for determining a safe System Earth (Ground) has shifted away from an arbitrary Resistance figure, usually <1 ohm.  It’s still all too common to see this outdated measure of installed success appear on client/employer requirement specifications(ER’s) as part of the Earthing Calculations Design Safety.

BIM Earthing Design – What Does the Future Hold?

In a previous post, we introduced BIM earthing to Electrical Earthing Design and cleared up a few misconceptions. In this post, I’m going to suggest where I believe BIM might be going.

Where is BIM Earthing Design heading for Lightning & Earthing?

Currently, most projects operate at BIM level 2. Where each trade has its own 3D model, stored locally on various engineers’ computers, or perhaps on a network folder. This folder is accessible to all (authorised) staff within the organisation. In some organisations where BIM better developed, oven combining these models for the purpose of clash detection. This ensures that, for example, the Earthing contractor doesn’t intend to install BS7430 earth electrodes in the same place as a civils contractor’s ducting/drainage.  All of these exist only in 3 dimensions.

BIM Earthing Demystified… Cutting through the endless jargon

BIM earthing?

If like me, you’re a little confused about what BIM REALLY means. This article is for you. It covers some of the misconceptions and demystifies a few uncertainties – without the Governmental jargon!

Let’s start with the basics…

What is 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.
