- I've done some internet searches, but haven't found alot of useful information. Does anyone have some links to websites/pages that describe the phenomena of rain induced static due to rain on HV or M

- I don't know a great deal about static induced directly by rain hitting HV lines, but here in dusty, sooty, gritty, 10-inches-of-rain-or-less-per-year San Diego County, I do know that the first rain

- This is something different. I think I'm talking about corona, but I'll let others comment. I have some HV lines nearby. I get static on all bands whenever it rains. The static stops within a few min

- Mostly, corona is a fact of life - the voltage is higher than the damp air around the conductor can insulate. The following link sums it up: http://www.sciam.com/physics/article/id/what-causes-the-no

- Well I'd be interested to know why my power line noise (Low/ Medium voltage lines) seems to STOP when it rains. When the WX is dry it's very bad! What causes this? I'm in France. F5VJC ______________

- Yes that is how it normally works on lower voltage lines... the rain does 2 things right away - swells the wood so the hardware gets tight; and gets in between any nuts/washers and "bonds" them. Most

- Let me second Don's advice; I have a noisy pole about 400 meters from my antennas that is S9+ when dry and silent when it rains. In fact, that is one of the defining characteristics of low/medium vol

- Absolutely correct. Rain (or even dew, dampness, and sometime high humidity) will lessen or eliminate power line noise. It can be helpful to mention this to your utility, because if they come out whi

- Hey everybody and Happy Holidays, This is at the end of my awake hours but I'm going to attempt to do this and make sense. The power line systems constructed with wooden poles are built when the wood

- Hi Don. I think the problem lies with any liquid precip that is present; IIRC on past study of this subject air with higher relative humidty has a *higher* breakdown voltage (see the references below
