I found a link the the OPPD site.

It covers Phone line, Cable and powerlines coming into the house, I think
its around $6 a month to have it.   Installation I think was $50.

They cover up to $50,000 in damages.  Again, I think you have to jump
through a few hoops to porve lightning fried the equipment though.

Maybe this could be a OLUG meeting subject?  I don't mind discussing it at
the next meeting...(did I just volunteer?)

One thing to remember about Surge Supression is that the supressor you
buy is only as good as the power runs in your house.  A prerequisite
for a Surge Supresser is a properly gounded three-prong outlet.  For about
$5 to $7 bucks, you can pick up an outlet tester at Menards.  This is a
standard item in my toolkit.  Very useful for Lan Parties.

Plug it into the outlet you plan to put your UPS/Supressor on - there is
usually three lights on the end, with instructions on how to read the
lights printed on the side.  If the outlet tests anything beyond normal,
don't use it, you may be sorry (most likely No Ground, or Hot Neutral).
Also, Two-prong outlets are not considered safe.  These are non-grounded
plugs, don't trust an adapter.  Also, if you have a house with a mix of
two-prong and three-prong, chances are the three-prong outlets were
installed to avoid the use of a three-prong to two-prong adapter.  Best
bet, always test your outlets.

Putting Surge Supression on an AC power line is only part of the picture.
Telephone, Cat-5, and RG-6 (coax cable) all need protection, as any one of
them plugs directly into your PC.  These are often overlooked items. The
APC BackUPS Office has Phone/Cat5 protection.  Having Surge Supression on
your cable/satellite coax lines is essential if you have a Home theatre
system, which often has more investment values than some PC setups.

I do not remember if the Whole-House surge supression covers Telephone,
CAT5, Coax runs.  Spending a little money in these areas will save you
later.  Does anyone have whole-house suppression from OPPD?  What fee do
you pay per month for the service?  Installation?

A good habit to get into is to check your surge supressors after each
electrical storm.  You never know if any of them have been hit.  Check the
LED status.  A medium to high-end supressors, you will usually have a
"Protection" status LED - if this is not on, replace the supressor, as it
has done it's duty.

Surge Supressors with higher Joules ratings are always better.

Underground wiring will help with some surge situations.  I moved last
December to a subdivision that has underground wiring -
we lost power around 4 AM on Sunday May 4th.  I saw
the light from a few OPPD trucks inspecting the above-ground lines in my
area (120th and Military) - power was back on about 30 minutes later.
I know it was May 4th because I had to re-program my VCR to record the
F1 race at 6:30 AM.

I have several APC UPS units at home.  My main unit, APC SmartUPS 900, is
a bit older, but still works great.  I followed the directions from the NUT
site to build my own APC cable using a couple DB-9 plugs and a Cat-5
cable.  Using PowerChute, I can have my PC shut down automatically after a
given amount of time.  I have a small APC BackUPS 300 for my cable modem
and router.  The smaller current draw allows the 300 to stay up longer.

NUT is the Network UPS Tools.  I believe you can have one host monitor the
UPS through the signal cable, and notify other hosts on the same UPS to
shut down.  Very handy for multi-host environments on one UPS.
