Stuff talking about is arcing- 6o cycles should
have little to do with it. Also, had friend with
lamps going super bright , he got electrician to
go thru his power panel, and outlets- several 100$
later, got hold of power company, and they kept
stalling him (no problem found). after it also
ate several appliances, told him to keep checking.
As I suspicioned, on the power pole, they found
where a lightning strike had annealed the Neutral,
at it's connection to his service, and ground
wire! Point being lots of these services haven't
been looked at in years, and drying out/ vibration
on these can cause a lot of greif! Jim NN7K

Is the noise a 60 cycle hum ? or just noise in general? qrn or qrm?
I still think that it is a grounding problem .

I could be wrong but it sounds like thw same problem I had untill I
expanded my ground system and tied it to my utility (meterbase ground)
Then all the noise, vanished....
My 2 cents

Another reason is that as things dry out, the
connections to the pole Losen up , as the pole
shrinks, relative to the hardware. and- induction
to , say Crossarm Braces , can cause arcing ,
between those braces ! A way to check for this is
to give a pole a swift hit with a hammer. If the
noise goes away, or is changed, probably is loose
hardware on the pole . A thought for your
consideration- Jim NN7K

news What is it about general "noise" that makes it go way down during rainy
weather?
