No, the big generators at the power stations, and the big power lines
than connect them. Still, I remember studying them in third and fourth
year at university, something I believe that you missed out on.

In a AC power system the only energy storage you have is the spinning
mass of the turbine/generator.

** Not one - but as large number of them in unison.


** ???????


That is - on a high res frequency meter, the effective AC supply
frequency varies from say 50.1 to 49.9 over a couple of minutes then
drifts back again.

It can fall well below 49.9 for several minutes if there is a problem
with an alternator.

Shame how not even ONE of them meets the meaning of "well below".

Please explain what YOU mean by well below? I know you snipped them
because you can't stand being wrong, but I would 49.74 Hz well below
49.9Hz in the context of power system frequency control, and it stayed
below 49.85 for 458 seconds.

He says the alternators have rotation counts each day and are almost never
the same.
** All the alternators right across the Eastern half of Australia are
phase locked when in use.

The phase angle of each generator varies....

** But the rpm does not.

So "phase lock" is the case.

No, it not a "phase lock", as the phase between the alternators is not
locked,


** You cannot read - you sickening autistic prick.

Phase locked = no change in rpm between units.

No, Phase Locked = no change in the PHASE ANGLE between the units. As
there is a change in phase between alternators depending on the load,
they are not phase locked. Again, something you might have learned about
if you finished studying.

"T.T."

My new VHF antenna has an adaptor with two short insulated wires at one
end and a screw-on attachment for the co-ax at the other end. The two
wires are meant to be connected to the arms of the antenna, using the
wingnuts on the antenna, and the co-ax is connected to the other end of
the adaptor by a screw-on device that grips the shielding of the co-ax
with a threaded cylinder and screws to the adaptor with a threaded
hex-nut.

My question, before I caper around on the roof like a twenty-year-old, is
this: The resistance between the two wires, even without the co-ax or the
co-ax connector being connected, is zero. Unmeasurable. This cannot be
right? Can it?

** Yes it is right.

The tiny windings of small RF baluns have negligible DC resistance .

One needs pretty fancy RF test gear to measure the actual impedance in the
VHF or UHF bands.

** The Sydney based " Jands Electronics " used to manufacture a high
powered stereo amp for sound system use called the SR3000. The designer
employed by Jands was Doug Ford, whom I knew fairly well and is my
informant here.

The SR3000 amp used a system of four DC supply rails for the output stages:

The voltages were: +150 +75 0 -75 -150

Also, to save weight and cost, the heatsink assembly was divided into
separate sections and isolated from the case - so the output transistors
were not insulated from the heatsink.

Yep, the various sub heatsinks were "live" at the four DC supply
oltages - with heaps of current available.

Aware this just might be a hazard to service personnel, Doug made sure the
fact the heat were live was boldly marked on some clear plastic covers that
directed air from the fans through the assembly.

But this was not *before* a very nasty incident in the Jands factory:

One morning, a number of freshly finished SR3000s were sitting happily on a
large trolley under going "soak testing".

Then, the boss of Jands ( David Mulholland ) decided to honour the factory
with his presence and inspect progress with the new whiz bang amplifier that
has just be put into production.

What do you reckon was the very first thing the boss did ?

What words do you suspect he immediately uttered ??

His loyal tech staff were all convulsed with hysterics.

I was gunna opt out of this thread but I have to clarify a point or two.

The people under the bandstand were covered by the roof. Now it may have
been that the strike ionised the air all around, and inside, but I
guarantee that the wooden structure (mostly dry - it had a roof
remember) was also a path.

Have you ever seen a large tree split in half by lightning? What has
happened? Think about what forces are occurring in that tree to
literally blow it apart. What is it that has passed through the wood, to
cause, I assume, a large build up of gas?

I get the feeling that a few otherwise intelligent engineers, techs etc,
don't quite appreciate just how powerful lightning is...

Wood will conduct lightning!, what are you
worried about!!.

Actually, wood doesn't.

Put enough volts across it and it certainly will.

Its not the wood thats doing the conducting.

Yes it is.

It is if the wood is wet. Take a look at any photo of a lab strike
to a dry peice of timber. The lighning travels around the outside
of the timber. Put a piece of plastic next to the piece of wood,
and the plastic will also produce the same effect. I beleive the
term is called flashover. The same phenomena affects ceramic
insulators.

Wrong, as always.

Its an exact sector copy of the entire hard drive and

You claimed that an image file is always involved. You are wrong.

Nothing like what you originally pig ignorantly claimed.

Wrong, as always. There is no image file involved with a clone
of an almost full hard drive to a drive of the same size when using
Drive Image, Ghost, True Image, xxcopy, xxclone, etc etc etc.

You only use True Image ,

Wrong, as always.

sure its does on the fly cloning

So does Drive Image, Ghost, True Image, xxcopy, xxclone, etc etc etc.

but thats only one small option for cloning drives ,

Its the ONLY option possible when cloning an almost
full hard drive to a drive of the same size because
there is nowhere to put the image file, fuckwit.

there are 50 products out there

Duh.

and your speaking about 1 thats not used by the professionals .

Pity its also true of Drive Image, Ghost, True Image, xxcopy, xxclone,
etc etc etc when cloning an almost full drive to another of the same size.

Why take an image if its not a backup and repeatable on the deployment .

What matters is whether its FUNCTIONALLY identical.

There are significant downsides with sector by sector clones,
most obviously that the two physical drives need to be identical.
That is NOT the situation in which most cloning is done. Its MUCH
more often done when upgrading the boot drive to a new bigger
drive and a sector by sector clone wont work in that case
because the clone will be the same sized as the original, stupid.

Also a file is much easier to audit for backup
retrieval, rather than a physical drive.

Pity that the most common use of cloning doesnt need any audit.

This argument is typical homeboy stuff.

Couldnt bullshit its way out of a wet paper bag even
if its pathetic excuse for a 'life' depended on it.

I think your wrong in your conclusions .

Nope, as I proved with the example of an almost full hard drive being
cloned to the same sized drive, there is nowhere to put the image file.

Have another go on this most basic of topics .

Its you that need to do that.
