Lightning Protection
(OP)
Anyone,
If I have AHU(For HVAC made from steel) on the flat roof of substation so please advise that we would need Air Terminal on the roof or we just use AHU instead and connect to bare copper directly to earth.
Thanks

RE: Lightning Protection
I'd fit a proper air terminal connected to a suitable earthing system, assuming you're not already in the area shadowed by another larger structure (e.g. a transmission tower or adjacent building).
