Hi all,

Power line conductors need to be above a certain diameter to avoid
power-robbing corona discharge. I have noticed that under certain
conditions, there will be a little bit of discharge evident as a
buzzing sound in the power lines. Other times, it's not buzzing.

I assume that for a given metal surface, the threshold voltage varies
depending on humidity, temperature and air pressure.

If you beam energy (microwaves or UHF) through power lines, would that
increase the likelyhood of corona discharge? Does sunlight have an
effect?

Can the corona discharge phenomenon be used as a radiation detector? I
mean, a general purpose detector that works with ionizing,
non-ionizing and EM radiation?

Brad
