* *Where did I say HOW was protected? It was my second week at that
station, and the chief engineer took off on a long overdue vacation. If
you would learn to read, rather than just do mindless rants you wouldn't
look so stupid. *At that time the building had a UFER ground, and a
three phase protection system at the meter CTs. That didn't prevent the
damage, as you claim it should.

* Lightning created damage. *Since Michael Terrell says it had an Ufer
ground, that means grounding was properly installed and not
corrupted? *Therefore the resulting damage proves, "Woe is me.
Nothing can protect from lightning."? *Nonsense.

* *That's it, _wacko_. *Use more misdirection. *It is YOU who claims
that broadcast facilities sustain no damage from lightning strikes.

* Damage was created by a surge. *A responsible human locates the
defect in that protection system. *Michael Terrell was defeatist. *He
'knew' nothing can earthing lightning without damage.

* *More _wacko_ lies, as expected.

* Then Michael posts nonsense about other protectors so he need not
admit this fact: MOVs are not used on telephone lines. *Why discuss
fuses? *Fuses obviously are not for surge protection - when one has
basic electrical knowledge. * Effective protectors (even gas discharge
tubes - GDTs) earth direct lightning strikes and remain functional.

* So why is Michael now discussing GDTs and fuses?

* If you could read and comprehend you would know. *Sadly, you are too
ignorant to understand what you read.

*Michael has again
been caught posting in error. *MOVs are not used for telephone line
surge protection due to excessive capacitance.

* *Liar. *You keep telling this lie, even though I posted links to two
telephone cards using them, as well as the datasheets form one of many
OEMs who make MOVs for Telecom service. *The stated capacitance is 480
pF *Tell us how that affects the bandwidth, when the line to the
building has a higher capacitance.

*This has long been
common knowledge among those who post facts - not insults.

* *gee, stop posting lies and insults, and learn the truth.

*Nnoted and
finally admitted by Michael is a reasons why so little lightning in
the UK creates so much damage.

* *Another blatant lie. I never mentioned anything to do with protection
in the UK, _wacko_.

*Master sockets are not even earthed as
the equivlant NID is, routinely, in all North America.

* *You didn't even look at that Epcos link, did you? *You can't admit
that you are the biggest idiot and liar on USENET. *It doesn't really
matter, everyone sees through your pathetic attempts to distort the
truth. When that doesn't work, you fall back on lies and omissions to
smear anyone you don't agree with.

* Responsible people who suffer surge damage immediately search for
the human failure that made damage possible.

* *I did look. *What I found was large chunks of concrete blown away,
and pieces of burnt rebar from a direct strike.

*Search typically begins
by looking for defects in the single point earth ground system.

* *Now UFER is single point in a 10,000 Sq. Ft building?

*Those
who promote magic box plug-in protectors would not do this and must
assume lightning damage cannot be avoided - a defeatist attitude.

* *You are the one with an attitude. *Very little can be done to protect
from a direct strike. Some towers have had entire sections vaporized
from multiple strikes during a single storm, yet you continue to lie, by
stating it can't happen. No where did I claim that plug-in protection
was used. *This is another of your lies. *You ignored the fact that I
had never even seen most of the building, because I was just hired. I
was in the accounting office, right by the side door, and parking lot
where I filled out the application.

* *Here is the part you snipped, because you can't tell your ignorant
lies, and leave it in:
__________________________________________________ _________________________*_

* *Gee, _wacko_ you've never seen ANY modern business telephone
equipment? *Gas tubes are fragile and very expensive. The protection
isn't to save the privately owned telephones, it it to limit damage to
the building. *Even that mid '60s 1A2 system had every output of the
power supply fused to prevent a fire. Explain why an MOV's capacitance
is high enough to affect a phone line. Never mind. *I have a Nitsuko/NEC
DX2NA-32SYTEMEM KEY TELEPHONE SYSTEM in front of me, and every CO line
in it has a MOV across the line. *Once more, you're preaching lies and
using deceit to try to make others look bad.

is the Central Office line card for four telephone lines. See the black
MOVs to the right of each pair of fuses?

http://refurbishednitsuko.net/productInfo.aspx?productID=f5453e33-047....
is the card for four standard 2500 type telephones, or equivalent
equipment. See the pairs of black MOVs over the blue connectors at the
bottom of the screen? They are all japanese, with no brand markings.

http://www.epcos.com/web/generator/Web/Sections/Publications/PDF/SIOV...
is the Epcos MOV databook, with datasheets for Telecom applications.
page 213 list the TELECOM MOV data.

* *Every line into that studio building had a long distance call device
diverter in the line that had MOV across the phone line. Every one of
them survived the direct hit to the building and STL tower. That's more
than can be said of your ability to use reason, and learn new things.

* *You need to get your head out of 1920 and learn modern electronics.
The one thing we learned today is that you don't know any more about
Telecom that you do lightning protection, or reading comprehension.

LOL Haven't you seen W_ in action before? This is one of his
standard rants repeated many times. According to W_ any damage from
lightning or surges MUST be do to HUMAN failure.
