For those who want to skip it, this is not product safety, just a
digression from the electric shock topic.
As for why the chest thumping works, take the heel of your hand and
whack yourself on the side of the head. You'll notice the effect as
quite a few cells depolarize. That's the general
To answer the below -- KT has had the equipment for about 10 years.
For rental -- call Transient Specialists at 866-364-7368.
For robustness -- need to know the load. Large in-rush currents are
generally no problem.
I agree about the Pacific Power units -- we evaluated them here some years
ago --
True, but did KT have this equipment 4yrs ago?
Does anyone you know of rent this equipment?
We also have a Schaffner tap switcher, but it eats itself under heavy loads.
Is the KT stuff more robust under heavy startup loads?
The Pacific Power equipment I use has never broke down. Worth the
Seems to me this is the hard way to do it.
KeyTek has a product that is a tap switcher for the required levels and will
pass the in-rush currents required. It's a much smaller package.
Also, other manufacturers have systems that are basically software
controlled switches -- bring in the

Hi William,
I dont know about renting equipment for the tests.
You can probably find it.
For the -4-11 (dip/dropout) test;
Depending on your load, your site wiring has to be up to snuff.
The power sources for doing the dip and dropout test are hefty stuff.

Hi all,
John Crabb asked me about my previous response (see below). He brings
up some points that I don't have experience with. I wasn't sure how to
answer it. I was hoping that someone else could address his concern.
For our AC powered equipment, we have never needed to add varistors,
Robert,
Thanks for this very interesting piece of data. I've often wonder what
atrioventricular fibrillation is, you provide some insight on that as well.
If it is a reset of sorts then how did the thumping of the chest ever
work? I suppose it can also fall into the category of just being
excellent - now if you'll go through the PQRST complex
also...

You are all making some excellent points.
It would seem that many of us share commonality. Perhaps that is one of the
underlying purposes of the quality organizations. When followed, the
effects are positive and things move correctly, and in synch, but when
exceptions are present...
In my case,
I also have not encountered the theory about chest compression
controlling fibrillation. Since defibrillation is also controlled during
open heart surgery by paddles directly applied to the heart and through
the use of wire catheters from implantable defibrillators, it is not the
only means.

Hi Group,
Could anyone tell me a little more about the safety implications/standards
for the use of EL wire/sheet. Specifically when powered from a battery
source,i.e. battery-inverter-EL, and the EL wire/sheet outer insulation
is exposed.
Thank you in advance,

Actually, Vilfredo Pareto (1848-1923) was an Italian economist.
He observed that 80% of the economy was driven by 20% of the

turnover.

Didn't see a response to your question. Got lots to do today, so I'll

Hello KC Chan,
In Thailand the bands 26.960 - 27.410 MHz, 77.9875 - 79 MHz and 244.9875 -
246 MHz are
designated as Citizens Band (CB). The bands 79 - 79.9875 MHz and 246 - 247
MHz are
reserved for similar purposes.

I think the point raised by Gary re: where the Compliance group fits into
the organisation structure is more important than procedures/process,
although I disagree with him about where that should be. Let me explain.
Having a good working relationship with Engineering is indeed critical,

Dear all,
I guess I should have known better than to open a can of worms and then
have the audacity to take a day off!! I returned today ( Tuesday) to find my

Hi
I got an enquiry about the walkie-talkie in Thailand. Does anyone know the
frequency band for this purpose in Thailand, and where I can get more
information about this.
Thank You

Hi Tania,
I just finished writing a procedure on agency certifications for a client
(prompted by their ISO 9000 audit). It became partly glossary partly
encyclopedia so sales, marketing, etc could find definitions and explanations
of what the agencies are and why we need the certifications.
