Humidity in the air makes that wayyy more dangerous because your skin will be highly conductive and the lower the resistance, the higher the current (which is what really hurts).
I’ve been a human grounding strap a couple times and don’t recommend it. I think the vibrating pain of AC (someone reenergized the outlet on me) is worse than the punch of high voltage (failing spark plug wire I grabbed with metal pliers while diagnosing a misfire).
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.
I have a 10KV electric fence. 5KV to 15KV is typical electric fence voltage in a farm or bear prevention fence. Can’t feel a thing unless you actually touch it.
They are also not lethal. Very low current, just very high voltage. So it only hurts like fuck, but won’t kill a human, cow, or any other mammal that touches it.
They can kill an animal (including a mammal) if they become entangled and give up out of suffering, though.
This is pretty rare, but can happen.
It’s virtually zero risk to a human, though, who can cognize things like getting their hand disentangled from a string (even in a panic situation), or to most mammals, which tend to jerk backwards on contact.
This is why you should never try to remove a tree from a power line yourself.
Electricity always takes the path of least resistance back to the source. A tree, and possibly your body, may end up being the “path of least resistance”.
You won’t know if YOU are the path of least resistance or it the line is even energized until it’s too late.
about 10kV per cm i believe. you’re only at risk of it arcing to your body if you’re within a centimeter of the wire. and that assumes your body to ground is a good conductor (it’s not)
A high voltage electric fence. At some point even standing in front of the thing is enough.
Air only has so much resistance itself. High enough voltage and the closest path to ground is where the charge will go.
Just like with Lightning

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.

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.
With enough voltage, everything is a conductor.

They can’t kill you, but I know from experience that they can knock you out for a bit if you get shocked through your head.

Yup, this is why I shoot fallen tree limbs with a shotgun.
Off of power lines, right?
Yup, nothin’ like a little buckshot in the mornin’.
Yeah for when the little plants and leaves and dandelion wisps fall near my deck I got some anti vermin shot rounds for the .38
At 10,000V and at sea level, you need to be at about 4mm from that fence for the air to arce.
A few posts above I was curious and actually went and checked it.
Also, a high voltage electric fence with indicator lights that he already knew were off.
