Kirk,

Sounds like a leaky insulator, if the intensity varies between rain and 
dry spells, then that is a good possibility.
Notify the engineering department of your power provider of the noise.  
Leaky insulators are also waste energy and the power company does not 
get "paid" for the wasted energy.  They usually will come out with their 
own "sniffing" equipment, but try to be around and have your portable 
radio handy if they don't hear anything.

Good luck,

Jerry  -  K0HZI
