High noise level except when raining, why?
I have a little experience with powerline noise here in semi-rural southern
Oklahoma. I can't claim any expertise but it seems to work like this; As dry weather dries the poles and hardware any arc sparking that occurs has to span greater arc lengths and gets louder. If w e get rain (not so common in the last year or so) the insulating factor of the dry poles and hardware is diminished, spark arcs are shorter and the noise is reduced. Not every electronic noisemaker is an outdoor iten, but if wet weather quiets'em down, they probably are.Last year I had 30 days of S9+ noise before the power companies "noise" crew could get to me and fix the problem. Turns out the pole with my power service connection had an arcing ground wire which they fixed in about 30 minutes. My background noise level dropped to a more tolerable S1 oor S2. My pole was an old one and the ground wire on the pole ran from the very top of the pole so it could act as a lightning rod as well as a regular ground wire (they said the newer poles aren't wired that way anymore). It, of neccessity,. ran close to insulator mounting hardware and that was my noise source. They cut the top couple of feet off the old ground wire, tightened the actual ground connections, and made my day.
