The arcing that causes RFI is usually not from the power lines
themselves, but various pieces of poorly bonded hardware NEAR the power
lines.

Lew,
That's in direct conflict with everything I've seen from RFI
engineers. Over the years, I've seen plenty of reports of hardware in
the power system failing in a mode that causes it to arc. See
http://www.arrl.org/power-line-noise for a great discussion of all
sorts of RF noise, including power line noise. At least 10 years ago,
I bought and read "AC Power Interference Handbook" by Marv Loftness,
a field engineer who specialized in that work. He said that virtually
all power line noise is caused by SOMETHING arcing.

Drawing from a decade of experience working as head of the PR
department for a major electric utility (a long time ago), I’d like
to suggest that arcing per se should not be a problem at any time
with any power line if it is functioning properly. The individual
transmission wires are spaced far enough apart that arcing shouldn’t
be possible.
