[Antennas] Ground rod questions (Ground currents)

I had the same symptom you have described here for your powe station at my 
house and a few years later our on our property in the country.  A 
significant load on one side wound lower that side to 80 or 90 volts and 
raise the other side to near 160 volts.  I finally figured out what was 
going on that the neutral was being "drug" over toward the heavier load side 
causing the rise in the other side.  At the house I was able to measure the 
problem coming into the breaker panel and called an electrician and he 
measured both sides of the meter and found the problem was there.  He pulled 
the meter and the connection for the ground wire behind the meter had to be 
replaced - fixed.  The farm was the same story but it was at the transformer 
hanging on the pole and the electric company fixed it.

Interesting problem,
73, de Jim KG0KP

My brain passed gas!


We had weird fluctuations whenever a load was put on one side, (120), of
the 240V drops to each building.  The one load side with the coffee pot, OR 
the side with the refrigerator that we traded for would kick in, that leg 
would drop to 80 - 90 VAC, while the OTHER leg would go WAY up to 160VAC or 
more.

That's what I should have finished.  It was all tied up in the lack of GOOD 
conductivity.  When the tide came up it would get well.  When the tide was 
out, those were the funny things we would observe with metering we installed 
at OUR service entrance.  (Scrounged from an old abandoned power plant.)
