Re education - 24hourcampfire

The next one thats leans on the fence is going to get lit up.

Lightning must have taken out the other one and they figured it out and started trying to get through the fence.

Some fences you really don't want to pee on (this one was a 240 watt, 3 phase).

Oh mama!

Um, what am i looking at?

Well done.

Lets just say his love life will be minimal from now on.

Holy S**t! Unbelievable.

Pat85's fence isn't going to that, thank goodness. My question is why anyone would put up a livestock fence that powerful. Keeping cows in isn't the same as barbecuing them.

This is from a livestock fence?

That's what the caption with the photo said. It's hard to believe that anyone who valued their animals would use one that powerful, though. It would take out a horse in a split second.
Pat85's fence is more than enough for any kind of livestock.

Trump's fence? Looks doable.

One of those two got the reeducation. The hay they knock under the fence with their nose wasn't cleaned up like before. Have to keep them out of the pasture at least another month to let the grass catch up or they will have it scalped to the point it won't recover before summer.

We run the 200 mile version from Zareba for goats, horses use the same pastures when we rotate but they don't need near that much juice. I think it is around 16 joules output. I can say it's caused more than a few choice words to come out of my mouth when I wasn't paying attention and got hammered....

If you get many lighting storms you may want to have a backup. Ours have been hit several times so we have a second one waiting in reserve....free range goats ain't a good thing. Within the warranty they will fix it for free but you have to ship it off. The place that we've used to fix ours has mentioned that Zareba has little protection from lightning and if it gets hit it usually has to be sent off.

I used to know a rancher near here who had lightning hit his fence and start 3 mile long range fire. It can be nasty.

Are you saying goats are hard to keep in?

I have one now with a full length cast on a front leg to fix a cracked bone. The vet said to keep him in a small pen while it healed. I built a pen but he got over a 5' panel fence with the cast on. I figured he'd hurt it less out in the pasture than doing stuff like that.

This new one came with some sort of surge protector that mounts between the box and fence.

FWIW, fencer makers advertise joules because it looks good but actually they're meaningless when it comes to fences. J is dependent on the length of the pulse as much as the wattage. A joule is the energy needed to produce 1 watt for 1 second. A fencer that puts out 5000V in a .01 second pulse will produce the same # of joules as a 10,000V fence (assuming equal amps) that has a .005 second pulse. Fencer makers can crank the joule rating way up simply by making the pulse a little longer.
Wattage (volts x amps) is what gets the job done.

Here's a good read on how it works: FENCE POWER
an except from the article:

watts x seconds joules
As can be seen by these equations, the
higher the volts and amps that an
energizer can deliver, the higher the
watts. And the higher the watts
delivered in the same pulse time, the
higher the joules. These equations are
important to understand when
comparing energizers.
For Example:
- Unit A is listed as a 4.5 Joule energizer
which can maintain 5000 volts under
low weed pressure. If Unit A's pulse
time, the time the fence is on, is 0.0003
seconds than we can make the
following calculations by reversing the
above equations to see how much
electricity the energizer is delivering:
4.5 joules/0.0003 sec. = 15000 watts
15000 watts/5000 volts = 3 amps
- Unit B also claims to be a 4.5 joule
energizer that can maintain 5000 volts,
but was rated using a 0.0006 second
pulse time. Using these numbers in our
calculation we find that:
4.5 joules/0.0006 sec. = 7500 watts
7500 watts/5000 volts = 1.5 amps
Unit B is actually delivering half the
amount of electricity of Unit A. If we
compare them equally then Unit B
would actually only be a 2.25 joule
energizer.
There are currently no standards in
effect to assure consumers that the
manufacturers and distributors of
electric fence energizers are fairly and
equally comparing the electrical
attributes of their products to their
competitors.

I'm not sure what the pulse time is on the version we use. I do know that the voltage is greater than any of the other chargers we've used according to our fence tester.

I haven't seen one that does give the pulse time. I have one with 16000V that will definitely stop the goats. It might be hard on horses, though. If the voltage is enough, it doesn't take much pulse time. It usually runs a lot lower than that. The 16k is a maximum with almost no fence length.

The one we use is listed at 15,400 with no load. Running at least 3 wires over 4 different pastures, some with cross fencing, at the longest distance from the charger we usually have 7,000+ volts. Vegetation and dampness of the ground have some effect but as long as it stays above 7,000 in the worst case I consider it good. We've not had any goats escape with this charger unless the fence has been grounded. At shorter distances, when we've turned off some of the extra pastures, and/or have a clean fence, the readings are above 10,000.

Cussed goats. I learned my lesson about goats with horns. They'd stick their heads under the wires than get shocked. When they jumped back, they'd hook the horns under the wires and rip them off the insulators.

the really high output fences are generally meant for animals with little respect for fences like bison.

dad had a customer sell his bison, then the daughter wanted a horse so they used the same fencer, horse got his foot caught in the fence somehow. it resulted in the whole hoof capsule being pulled off and the fence all but cauterized the bleeding.... not a good outcome although better outcome than the poor guy that peed on the fence
