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.
Dry? It was a carribean island, right? Probably humid as fuck.
Yes, but it isn't hosing down with rain.....
It was the night before.
That buzzing sound is terrifying, by the way, if you're close enough to a very high voltage.
In some way it is comforting, you know the power is where it is supposed to be... Walking around a 11kV switchyard that buzz is good.
An interesting way to hear this without endangering yourself is to be near transmission lines in a light rain. Some go over a local park near me, and it’s wild how well you can hear it sometimes.
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....
10/3 millimeters away, to be precise.
