Hi Gangue,
Mike is absolutely right in his above mail. There is NO reliable
lightning protecction that can be guaranteed to work.
Those of you who know me will be aware I work for the electricity
supply company here in Scotland, and I am an "authorised person" in
terms of the UK Electricity Supply Acts up to 400Kv licensed. I am
also as Mike is a telecoms engineer.
At best, we hope to minimise damage in storm conditions by closing
down any un-used portions of the national network where possible, at
worst, we just have to repair when necessary.
Regards
Mel
