A high voltage electric fence. At some point even standing in front of the thing is enough.
At approx 3kV/mm, you would have to be pretty close to a 10kV fence.
Humidity plays a big role as does the frequency that the fence is running on. But you would be pretty safe standing a meter away, on that dry sunny day in the picture.
Also above a point, the high voltage causes the conductors to buzz.
If I'm not mistaking the buzz is because it's AC hence the buzz frequency is the same as the AC's.
Certainly it makes sense that the high voltage would be generated from mains power using a big fat transformer since that's probably the simplest way to do it.
Yep.
The highest DC voltage I have been near is around 1000V, it didn't buzz, but 1000V AC also doesn't buzz....
