The power supply doesn't matter. An electric fence depends on high voltage to delver a (mostly) harmless low current but painful shock. It has to be carefully designed to limit the current and duration of the shock, and have other safety features.yeah i will use battery 12v
But it does.The power supply doesn't matter.
I was referring to the 12V battery comment, which I surmise the TS thought he might just apply to the fence.But it does.
A line powered fencer could develop a short between the mains and the fence, which could be lethal.
Such a short for a battery powered fencer would not.
I have not seen a do-it-yourself circuit for a battery powered fencer that is significantly dangerous.
They generate a short duration high voltage pulse using an ignition coil or similar which I don't see as being lethal, any more than that generated by commercial fencers.
I have never seen a warning that the spark from a vehicle ignition could be dangerous.
If you already have a fence the goat should already be confined. If you do not have a fence consider an "invisible fence" as used for dogs. This eliminates anyone else being a victim of shock. Just Google invisible fence. After a few shocks your goat will figure out the boundaries. Goats are remarkably smart.Hello guys, I need to make an electric fence for my goat. Can you please help me and give me an easy method to make it?
I fell comfortable suggesting the building of a typical ignition-coil, battery-powered fencer, as I don't see how that can be significantly dangerous.If you feel comfortable suggesting a person without knowledge about high voltage create an electric fence DIY
Every commecrcially sold fence charger that I have seen delivers short pulses of high voltage, not a steady charge. A constant voltage fence charger is designed to kill, not just deter. It would never be used for livestock, but rather as a lethal protection system. Even the "Black Max" anti carjacker system only delivered a fairly short shock, intended to knock a carjacker to the pavement.In may countries you must post signs on the fence that people can read and goats can not. lol
Also it is important to have the fence turn off for a short time to let people and animals get off the fence. People will grab the wire and can not let go when the power is on. It is important to turn the power on then off for 1 second. I can not find the law right now.
If you find the neighbor's child dead on your fence you will have bigger problems than a goat. (back to post #3)
Most of those use a special designed high-voltage coil which may not be readily available.Most that crossed my path had the schematic pasted inside the cover and they are all copies of one another. Also search the net, this is no proprietary information an it can easily be found.
Actually, for battery operated systems where isolation of the power supply is not a safety issue, the older type of automotive engine ignition coils that worked with a distributor would work quite well. And those should be available almost everywhere in the world.. A 2 millisecond pulse every two or three seconds should be enough to startle an animal investigating a wire. I am not sure how it would affect deer, though.Same, easy to find, coils as in furnace igniters.
