4KV on PCB (Esd Test)

Trust me, that PCB would have fried chips long before that spark gap
voltage would ever get reached.

CMOS can get killed with as little as a few volts, and typically get
killed by less than 30V.

Just raising your arms in the air in a dry lab with no ESD smock on
can generate that much differential.

I trust You,
but this only a test for verify the discharge of high energy before the
protection device
(against the destruction of transil and varistor)

In Telecom PCB, we use primary protection and secondary protection,
the PCB acute (tips) are only an additionally protection

That would probably work better sticking a carburettor on the end of the
hose.

Is that what people do with broadband,
waste Internet bandwidth
mean while my 56K dial up is getting slower and slower

HOLY SHIT!!!!!!!

That is absolutely AMAZING!!!!!!

Burned enough power in that one run to power a town.

YouBOOB is lame. That clip was longer, and every time some tard
uploads it, it gets snipped back further and further.

No, it didn't "burn power" Whatever load was on the load side of
that switch still got fed while the plasma was arcing.

It burned power in the sense that all that flash and bang dissipated
dozens of kilowatts exciting our rods 'n' cones and eardrums, which
therefore _weren't_ available to be dissipated in the load. Something
still got "burned" at the source to produce them. What I find more
impressive is the fact that the plasma carried the load part of the
power silently! Since that was likely much more than the flash/bang
part, I'm pretty sure the latter's not enough to power a "town"
though. ;>)

Part that bugs me most is the primal yell at the end that usually
gets cut off. Took the, um, "word" right outta my mouth!

Some months or years ago, someone gave a detailed description of what
exactly happened - there are actually two switches there, and you can
actually see the thing just to the right of the arc terminal burn up;
this contributed to the big arc - I don't remember exactly what that
first failed part was - some kind of arc quencher that failed, I think.
I'd look it up, but google groups search is way broken, so it's not even
worth the bother.

Maybe somebody else remembers.

Thanks,
Rich

I seem to remember that it was a three phase switch, and all three
were supposed to open, and only one did.

The grid banging transformer fire/explosion was a pretty good video
too. Wouldn't want to be within a hundred feet of that one...

Post the links again, and I'll give you a pretty detailed description.
I think I've seen both of these.

Thanks for that, Bert.

A snippet from the site:

"As impressive as this huge arc may be, the air break switch was
really NOT disconnecting a real load. This arc was "only" carrying the
relatively low (about 100 amps) magnetizing current associated with
the line reactor. The 94 mile long transmission line associated with
the above circuit normally carries over 1,000 megawatts (MW) of power
between Boulder City, Nevada (from the generators at Hoover Dam) to
the Lugo substation near Los Angeles, California."

OK, so there wasn't a "real load", just 100 amps keeping the reactor
magnetized. So was the arc "burning power", or not?

Aw hell, I dunno. Still fun to watch!

Hey. I offered to help. You told me to piss off. Goodbye.

No. I told you to read the thread. How hard can it be, and how is
that my fault that you cannot?
