 ```Jim: As you can see from the patent app, it's been over twenty years since I worked on this system. My memory is ...., uh.... hmmm.... what was I saying? I'm afraid I can't give you quantitative answers (How long a barbed wire fence do I need to induce X volts in it?) The answer depends on the geometry of the two wires (how far apart are they?) and the operating voltage of the line itself and, I think, on the load actually carried by the HV line. We did the calcs back in the power company based on the specific spatial configuration of the wires in the transmission line. As I recall, for our 230 kV line at PP&L, we needed at least three 600-foot long spans of ground wire, separated from the main conductors by thirty feet or so (the average separation at that voltage) and insulated from the tower itself with procelain insulators, to pick off a couple kiloWatts of energy at a couple thousand volts. We included a pole pig (pole mounted transformer) in our design to reduce the couplakilovolts down to 240 VAC for use in our invention. BOTTOM LINE: If the line is long enough and close enough to a power line that's hot enough voltagewise, at a minimum you could get a nasty bite from the fence. 73 de Gene Smar AD3F ----- Original Message ----- From: "Jim Miller" To: "Gene Smar" ; Sent: Sunday, January 25, 2004 4:32 PM Subject: Re: [TowerTalk] New power line phenomena problem > Interesting, > > 1.
