This is scary!
How do you know if you are exposed to such trouble?I think in my small
property it would be unlikly to develope such a problem but with somebody
close to a power sub station or heavy industrial power supplies/supply
lines/tranformers it could be a real problem!
I know about a case where a powerline engineer was killed because of an
earting problem 1/2 a mile away, imagine the power
available to cook your core,excuse the pun. Tom, how do one check on this
potential problem?
