Bulk feed bin energized

[MJMJ]

Not sure what you’re asking, but in reply 3 he says it stops when he unplugged the charger. I think he means he suspects the voltage is coming through the saturated earth, from the charged fence due to foliage contacting it around the perimeter. You are proposing to disconnect the charger from the fence and operate it disconnected to see if it still causes a problem? I wonder if silo stave material would be conductive or not? Should just be some form of cement

If I understood him, he was theorizing it was coming from the fence, through the weeds and into the saturated soil and over to the bin. Thats really easy to check by unhooking the fence from the charger.
But now I wonder if I misunderstood. I have no idea what a call to the fencer company can accomplish. They aren’t there to troubleshoot, which is the only way to find the source of the voltage.

Everyone's ideas are valid. I am sure it has to do with the excess moisture. we have had fencers on several farms for my entire life and have not run into this. The ground rods are closer than 50 feet, I have never seen the 50 ft deal before and other than remote battery install have probably all been that close. The water piping is all plastic. I too have had fences that run under a 345 Kva line that will become charged if the the fence is very clean with new insulators and no grass. I know Stray voltage is a real thing and have been on several hunts for it in the past. I use a Gallagher fault finder meter on the fence. The digital meters(Fluke) don't pick up the voltage as well as the old sweep arm ones (Amprobe) do, like the one I borrowed to someone I don't remember. Water seems to be seeping out everywhere, last year couldn't buy a rain. The pulsing has gone away since I grounded the tank but still doesn't mean it isn't there. I am watching the cows closely on water but with water in every dip it's hard to tell. I think this too shall pass.

Yippeee! Radio system now off the Air. Jim

Ok but you can still get stray current from the house or barn through the water inside the plastic pipe but that may not be your problem here. A loose neutral somewhere may result on current through the water.

I was putting the door in my feed bin after cleaning it for new feed. Should mention we are super saturated here. I thought Had one of those little finger twinges you get sometimes but it kept repeating(I'm slow) realized it was the fencer very slight. there is no hot wire within 20 feet the 3 ground rods are close by. I checked the feed bin getting between 200 and 500 volts, nothing on ground rods. Fence had 2.7K grass and feed are really dragging it down. the feed bin is on silo staves on crushed rock. should I ground the tank back to the ground rods. But still don't understand why the feed tank should be pulsing like that.

Ground rods usually have dozens to hundreds of ohms resistance to earth .
Not usual to drive a 10ft ground rod and connect it to a 15amp breaker on 120V . Breaker does not trip but the earth worms soon rise to the surface .
Every ground rod should have #6 or #2 bare copper burrows between them and connecting every utility ground rod together

B&D, the 3 ground rods are for an electric fencer. Your replies would have more relevance if you read all the replies by others and what the OP has added.

start with the easiest first

Check the grounds on all the electrical panels and make sure the sub panels split the ground from the neutral bus

Then turn everything off and test one at a time until you find the offending device

Frayed cords, including barn wiring or misswired connections could be the problem.

If it’s a fence charger try moving the location of the unit further away

Good hunting
