Electric fence question

I've had electric fences all my life but I don't know the answer to this one. A cow out yesterday got me to thinking.

When I go out to check the fence I unhook it in case I need to work on anything. Could I ground it out instead? I was thinking of taking a rod and attaching an insulated wire and clamp like on a set of jumper cables. If I stick that rod in the ground and then clamp onto the fence won't it kill the fence even though it is still hooked up? I would think so. Except that would mean that when a cow hit it anywhere on the line the whole thing would be dead. Granted, only for a second.

I have a tester and was going to rig something up but I honestly don't trust the tester. The fence here at home is bionic - my goal everyday is not to get bitten by it and I never have. It literally killed a snapping turtle the other day that got hung up under it - one that was bigger than dinner plate size. I'm afraid that tester would read "0" but there would still be some stray or something.

It would just save lots of trips to the shed to kill the charger.
 
Earth grounding will "MOSTLY" kill it, but Id bet you "may" still get a tingle if you touched it.

It depends on soil moisture and mineral content and how good the ground is and how deep the ground rod and how good the connections are etc etc etc etc , A LOT OF VARIABLES

Try it and touch it is all I can say!!!!!!!!!!!! Or maybe have the wife try it first BUT WARNING you only get one shot at that so use it sparingly and ONLY if you really really need to know lol lol

Can you imagine???? I'd be washing my own britches until the cows come home (which would likely happen when the hot wire was grounded out).
 
Danofarming,
Years ago when we had a big garden on a lake, no kids around, we built a electric fence using a 10,000 volt transformer from a oil furnace. Took care of coons,but when a skunk hit it, it woke me from a dead sleep, it sprayed all over the place. We had trouble with a black bear,so we set a trap in the corn patch, it got the bear,but kinda pizzed him off, he tore the whole corn patch down and left a nice steaming calling card in his tracks, he kept the trap. Like I said it was years ago when no one lived around us, wouldn't try it now days,too much of a chance of a child or anything else getting hurt or killed by it. So we use a electric fence charger from Farm and Fleet to guard the garden.

I've had the same idea, but also never trusted it. I think John T has it right- it would probably get rid of MOST of the charge, but you'd probably still get a little of it. So I always just turn off the fence.

Did make a rig like you're talking about when we had our first place- it had a high tension power line running right through it, and the stray power was enough to charge the fence even with the charger unplugged. So to work on the fence, I'd unplug the charger, then go to the work area and clamp the ground wire on. Just for fun, I'd often stick the spike into the ground first, then see if I got a spark when I went to put the alligator clip on the fence. Generally did, especially if it was a dry day. I had to use that lash-up even on non-electrified woven wire or barbed wire fences, during the summer when the wood posts were dry.
 
(quoted from post at 12:41:42 06/12/14) Anyone here ever build their own fence charger?
ore than one. Other than one that was line operated & I wouldn't really use because of safety concerns, the problem I found was the lack of a good low impedance output transformer. For a few hundred feet, an ignition coil will do, but it won't drive long fence lines like the commercial units. Commercial units output impedance is low Ohms, where ign coil is in 5,000 to 10,000 Ohm range.
 

I have some hook and eye connectors. The hook side is dead, no power when disconnected, so I unhook the connector and throw it anywhere. On one connector to the garden fence the hook side has to be live, so I have a piece of plastic twine with a loop in it tied to a post off to one side and I put the live hook in it. The rest of the fence is on but where I want to work is dead.

Knife switches can be arranged to do the same thing.

We had an electric fence on my parent's farm when I was growing up, funny thing is people seemed to get bit more than the animals, seems the animals were smart enough to leave it alone after it bit once or twice. People on the other hand thought we were smarter than the fence. Funniest one I had happen to me was one spring we were fixing fence getting it ready to turn the stock out. My Dad had this big idea to wear his rubber boots (Yooper speak "Swampers"), I was wearing my normal work boots which at that time consisted of a pair of genuine Vietnam era Marine Corp issue jungle boots, a gift from an uncle who gave them to me 'cause he wore them enough in Nam and didn't care to take a trip down memory lane with them on. All went fine until after most of the day my feet were wet, dad's still dry, and yes he'd walk up to the fence and grab a hold of it, I'd cringe, he'd splice the fence, replace insulators and do a multitude of things one does when they're fixing fence. Comes down to the end and dad's short about three feet of wire to finish the job, without thinking he asks me to hand him a piece of wire....about three feet long please. I did, you can guess what happened, yep he starts YELLING at me cause HE got shocked.

Flat out funniest one I ever saw was we had a Paso Fino Stallion, we found out there wasn't much market for 1/2 Paso foals so we decided to only let him cover the Paso Fino mares we had and let the grade mares stay open for the year. To convince the stallion we were serious we ran a hot fence all they way around the top of his pen. One of the grade mares came into heat, she backed up to the gate on his pen, he thought the only gentlemanly thing to do would be to oblige her through the gate, one of them made contact with the electric fence. He squealed like I've never heard a horse squeal, sounded almost like a hog, the mare shot out from under him like a race horse leaving the gate. He ended up falling all the way over on his back, four hovvies in the air. Once he got up he walked around to the other side of his paddock, around the corner of the barn where he couldn't see any of the other horses, stood there all afternoon shaking his head back and forth.

After college I took a job with a dairy herd out in western Oklahoma. I learned different areas of the country have different practices. A common practice in Oklahoma was to run miles of electric fence around your wheat fields and run cattle on them through the winter, if you didn't have cattle you hired some out. Electric fences were almost like community property, we had wheat that was on sections where we had no buildings or power, but it was okay to hook onto the neighbor's fence. Part of cattle check was to test the fence. If it wasn't working you had to fix it. The standard procedure was each of the farm trucks had a steel post in it with a porcelain insulator, you'd use this to ground the fence out to allow you to fix it when you found something. The other hired hand and I spent one morning trying to find a problem with a fence, we figured out it was dead before where we hooked on. We stopped in and told the neighbors about it, they agreed to go one way, we started out the other down a common fence between their pasture and our field, found a few small things but nothing that fixed our problem. Eventually we worked our way around the quarter section. We ran into one of the owners, it was just before dinner, he stopped to find out how we were doing, we explained we weren't having much luck. About that time he cocked his head and said "did you hear that?" He reaches over and grabs a fence post, does a little jig and yells "I found it", seems the neighbors found the big problem that restored power to the section we were hooked on and at that moment we found that last little ground but forgot to lean the grounding post against the fence before touching it. The owner hopped in the truck and said "let's go and check the rest of the fence before dinner" Good thing he was driving cause we found a pretty big wash and since we were all looking at the fence seems no one was paying much attention to where the truck was going. Luckily some one noticed and yelled stop, the front bumper was hanging over the wash out, good thing we didn't run into it or we would of needed a front end alignment and maybe a new front 6" of Chevy truck.

Another Dairy I worked at had a owner that was an inspired amateur electrician, Bubba didn't have anything on him. One of his techniques was to run 220 Volt motors and such on a separate circuit that used porcelain receptacles that were normal 15 amp fixtures (two wire at that). I forgot that or didn't hear when he explained it. One day for some reason I had to unplug one of the fence chargers, when done I plugged it back into the nearest outlet...the porcelain. I really hated feeding stock in the back lot for the next week or so, every time I'd grab that stupid hot fence gate handle I'd get poked. Eventually the fencer burned out, some one figured out what happened and I got yelled at. With in a year I was in the Air Force, playing with bombs and explosives was safer than that darn electric fence.
 


You say a human gets a shock worse than an animal? I have gotten shocked with Dads fencer more than once and it didn't hurt near as bad as it did when I got hit riding bareback on a horse
 
I used to ground the fence to work on it, and sometimes it would still shock me a little. Now in this age of cell phones, I phone the wife and ask her to kill the fence for me. I've got a piece of orange ribbon tied to the breaker in the shop that feeds the barn where the fencer plugs in. She flips it off, and usually hangs around for a few minutes to flip it back on for me after I've fixed the damaged insulator.
