A few years ago I visited a power station. I swear that I felt something
as
I drove under the HT wires. I don't know what I felt. However, I was
left
with the feeling that I could tell when I was under the HT lines with a
blindfold on.

The voltages were 400k, and I only felt the effect 30ft either side of the
wires.

No doubts Donal. I worked in a nuclear generating station for two years. On
most days I'd get a static shock when I touched my vehicle, which was parked
directly beneath the 225KV lines.
