Lightning design for buried cables – really?

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 Strike Prevention

The most exciting concept to come out of the Lightning Protection sector for centuries is the idea of ‘Lightning Strike Prevention’. Now, preventing lightning itself is outside the scope of any working installation today.  And maybe something for the scientific communities to think over. However, preventing an STRIKE-attachment to a structure IS something that is here and now!

Lightning Risk – Looking ahead at future trend

EX zone protection

Lightning Risk. In a world increasingly driven by quantitative Risk Assessment (QRA) techniques. It’s important to understand what the predicted impacts are as a result of our current trajectory (as humans). For Example the direction of travel that the population of planet earth seems to be following – in terms of climate change: Increasing Lightning […]

Fear of Lightning Frequency Increase

Very few consider that they or their assets will be struck by lightning. People relegate the threat of lightning to chance and are confident it will not affect them. This is a mentality that may come back to haunt them if new scientific research is correct.
