I've heard of a tingle voltage filter but not knowing who makes them makes it hard to find one. Anyone use one of these before?

My personal experience is limited to backing onto a hot wire fence. LOL I dont recommend it to any one.

But seriously, if the cows are balking at the milking pen, have you checked your grounding and bonding?

I found an answer for the tingle affect. I guess what was happening is the cows were getting tingled from the water bin. There's a hot water tank fead from a sub panel. According to the gentleman I spoke with who happens to be a ferensic engineer on grounding. He said to drive a ground rod under the sub panel and drive a rod under the water bin. Attach with #6 at each location. Test it with a volt meter. PLace the setting on DC volts, run a lead from ground point at bin to sub ground and read if any stray voltage is present. It should be illiminated.

I'm not familiar with a "no fault" circuit, but there may be some info here
