[RFI] Rain induced static

[Kelly Johnson]

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 MV
powerlines.  I've found a number of things talking about static caused
by rain hitting an antenna.  I'm not talking about this.  I'm talking
about rain hitting an HV or MV powerline?
