Then he has a lot more understanding that I do as to which signal, the Wm or
the mW, is coming from that site :) . Every time there's a thunder storm,
and there's a quick power interruption, the darn thing reverses.
I'm still trying to come up with an effective way to kept the high power
surges, resulting from lightning hitting the power lines, from snapping
across the pump pressure switch and then finding a good ground at the
submersible pump, 210 ft down. Eventually there will be a failure of either
the pump motor or the pressure switch, maybe keeping the pump on all the
time and flooding the little cabin (built on a concrete slab and very
tightly constructed). Maybe there's some help out there?
Last week I was, again, startled by a loud pop from the direction of the
pressure switch. Approx a second later was the clap of thunder. This
computes to a quarter mile and indeed my friend a quarter of a mile away
reported seeing his utility pole receive a good bolt. There are ground wires
leading from the top conductor (the neutral of the 7200v line) on most of
the poles in that area but the ground conductivity is so poor that they
don't do a lot of good. Apparently it's a differential mode spike making its
way through the transformer, near the road, that steps down the 7200v line
to 120/120v because my new #8 ground wire running between the neutral line
at the breaker box and the well casing hasn't been effective. Was thinking
about adding a spark gap or a large MOV between both sides of the line and
the ground connection to the casing.
