I would like to see a discussion of lightning protection (sharp pointy objects) on your roof, versus the devices SECO uses at some of their substations, these look like a large Dandelion bloom. I worked in this industry and these are designed to DISSIPATE the charge and avoid the lightning strike. Sharpe pointed objects then at ATTRACT lightning strikes. These are applied to ATTRACT the strike to the protective wiring and away from the roof. May point is why not have the devices that dissipate the charge installed?
Looking forward to an interesting discussion.
