thanks for your very clear and helpful message. It was my
understanding too, that if there are say just a couple of overhead
wires only serving my house that they will be the same voltage as the
wires in the house itself. Its very interesting what you say about
the magnetic field (which is what i suspect is causing me problems)
and how it is dependent upon the demand coming from the house,
because even when i shut off all the electrics i feel pretty much the
same.
Does this mean therefore that what i'm feeling might have more to do
with the transformer close-ish to me than the wires feeding my house?
I have said in a previous mail that i have been in 2 places where i
can have the leccy on day & night with no ill effects, so its not
leccy per se that i have a problem with. There's something warped or
more loaded where i'm living. I guess i need to get a gaussmeter,
except i kind of don't want to know if the news is really bad!
