[TowerTalk] grounding

[Chris BONDE]

If your ground is better than the power companies you are in for some smoke.

A fellow ham nearby put in a great ground, he was also on some low laying ground 
near to a creek.  The power company placed its pole on the road allowance, the 
road was built up, well above the low laying surrounding field.  Guess what, the 
ground in which the pole was planted dried up in the summer, so o   o the grounding 
part went right through his system.  He just lost some minor stuff but could have lost 
the house if the wiring became very hot.

     i'm an electrician in the surge capital of the world, Orlando (
     did 
lightning just hit that house?), Florida. the last three days were
spent devouring old towertalk threads on grounding, super informative!
well, surge protectors are pretty useless without a good ground and
armed with towertalk knowledge i was ready to give my customer's the
best ground their money could buy.
     then, a really sharp engineer at Intermatic dropped this little
bombshell. if your ground is a lot better than the utility's ground at
the transformer then all the neighborhood's surges are coming for a
visit. and you might think they're just coming to your ground, but, as
they travel the common they induce surges in the two hots. So, you may
have dodged the big surge, and bought yourself a whole lot of little
ones.
      is this significant? do i need to put a big horkin MOV on the
      neutral 
to the meter that'll add a couple dozen ohms and keep the
neighborhood's surges out? is there such a thing?
     all kidding aside, i'm guaranteeing all appliances and
     electronics to 
$10,000.00 or the homeowner's deductable (installing Intermatic 
IG1300-4T-2C). please help.
