lightning protection system Archives

Continuing the theme for lightning design. I was having a technical discussion with a delegate, during a seminar in Germany. The question popped up regarding Lightning design on an AD plant (AD = anaerobic digestion). This site, with long-buried cable-runs, between plant areas. The delegates question, “What about the buried cables?”

What do we do about Lightning protection for buried cables in Lightning design?”

The question was not aimed at surge protection, but at physical protection of the cables from a direct lightning strike. And, before you say what? Yes, buried cables are at risk from direct strike attachments.

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.
