using well water for fence grounding
I am building a shack to enclose an old well. I will be trying to power the well pump using a home made windmill to charge a large bank of batteries and then use an inverter to convert to AC power.
Here is where the electric fence part comes in.... the paddocks that will be fed by the well are too far away from hydro to have a traditional plug in fencer. We tried 2 different brands of solar fencers, but just don't get the overall readings that we do out of the plug in type (we compared the two by running a generator and switching between them - the plug-in type kicked butt).
So, what I was thinking of doing was to put a plug in fencer in my well shack and run off a second inverter (1 - to separate the two loads and prevent brown-outs on the fencer, 2 - if the well pump fries the inverter I don't want the fence down to). Then I will bury an insulated power lead from the fencer to the fence (about 50-60').
My question is, Can I drop a ground rod into the well and use the contact of the water as an earth ground for the fence??
