    Oh and and also if you comparing units, Gallagher measures itís units performance in stored energy and pel/strainrite measures in kj of output, both make good units

    Induced voltage.
    But should be low amperage.
    One of the reason you shouldn't run fences parallel to hv lines.

    I'm in pumice country, but get a good earth using the bottom wire of a 9 wire fence. Where the fence drops down into a wet gully (100m from the unit) I have three earthing pegs connected to the bottom wire, buried down in the bog.

    If you buy a unit that comes with a solar panel, take the panel off and wire the unit up to a cheap 150 watt solar panel. The solar panels that come with energisers are pathetic, and only work properly in the middle of summer. Take it off and wire it to the tractor, to keep the battery topped up!

    We have it on really long fences with outriggers, I just run a bit of number 8 down through all the wires into the ground at the strainer to sort it.
    Edit I have no idea if this is fact its just what I've put it down to over the years

    That would have something to do with electro magnetic fields then. Surely.

    @andyanimal31 on my deer fences I run a hot wire at the ninth from the ground and another hot on the back of the post at the same height. My conventional fences are nine wire with top and third down hot.
    I get about 2000 volts building up on the cold wires either side of the hot ones. It's on pretty much all of the fences. And it's not shorts.
    Is that a earth issue?
    Sorry to hijack your thread 40.
    Brads summed it up with that been called inductance.
    Yep anywhere you are running electric fence wires parallel with conventional fence you will get that.
    It's a pain at gates when they get hot.
    Just force some number 8 or similar as far down the side of the strainer that you can into the soil then staple that wire over the wires that are wrapped around the strainer and it will earth the induction.
    Induction doesn't affect the voltage of the fence as it is not a short.
