Have you returned to constant current power distribution with 6 A
circuits ?

Arc lamps in the 1880's were specified by the number of amperes
(typically 6 A for street lighting). All lamps were series connected
and you could operate 20-25 of these in series from a 6 A DC generator
producing a 1000-1500 V DC loaded voltage. Thus, the voltage drop
across each arc lamp was about 55 V on average.

That's interesting. How would you strike an arc on series wired arc

lamps? Seems near impossible...?

When powered down, the electrodes touch each other.

When power is applied to the chain, the nominal loop current will flow
through the electromagnet and electrodes. The magnets starts pulling
the electrodes apart and when the electrodes in one lamp are separated
from each other, the loop is broken and the full generator open
circuit voltage (apparently 1-2 kV) is across the electrodes.
Apparently the inductance in the electromagnets also help create large
voltages peaks across the electrode gap, when the loop current is
interrupted, further helping in striking the arc.

When the arc and electrodes reaches normal operational temperatures,
the voltage drop across the arc is reduced, thus more voltage is
available across the other lamps to start them. I have no idea how
long it takes, before a string of 20 arc lamps will achieve a stable
condition.

Crickey, what is it made of?

Those Vishay Bulk Metal resistors:

are made of a proprietary variant of 75Ni-20Cr-3Al, which is roughly
an order of magnitude better than Shunt Manganin, and is the lowest
resistance tempco material known in the vicinity of room temperature.
One commercially available variant is known as Evanohm IIRC, available
as foil and wire in case you want to make your own resistors .

When comparing tempcos of different materials it is important also to
compare the specified temperature range or better yet look at the
resistance vs temp curve.

Low resistance TC metal alloys get their low TC the same way Invar
gets its low thermal expansion. Invar, at one specific temperature,
exactly cancels thermal expansion with a gradual phase change to a
lower volume phase. Low TC resistance alloys like Manganin and NiCrAl
exactly cancel tempco at one specific temperature with a gradual phase
change to a lower resistance phase. The further you get from the
temperature which is exactly compensated the worse the tempco in
either case. Specify TC very close to the compensated temp and you
can make it arbitrarily low .

Glen

Thanks. I appreciate it much better with the explanation of how it

Actually, they had a circuit that detected an "open" in the arc and

replaced it with a "short". The current increased slightly until the
failed lamp was repaired.

Incandescent street lamps were also used in series, with a similar
device to "short out" open filaments. These were on an AC supply from a
constant current transformer. See:

http://www.tpub.com/celec/5.htm

These usually ran at 6.6A, and close regulation was required, since the
life of an incandescent lamp is very dependent on the current.

Not the greatest up-close, but you can get some idea from the resistors
going into them. Made this class D tube amplifier a snap, plenty of pins
available.

Mine are flat, basically >1" wide strips of phenolic with lugs on there.
The advantage is that you get two lugs per contact so you don't have to
cram wires so much. The disadvantage is that you can't have multi-watt
resistors and stuff come too close or there will be a "burnt toast whiff".

Keystone still makes them:

http://www.keyelco.com/pdfs/M55p132.pdf

http://www.keyelco.com/pdfs/M55p133.pdf

Mine are double-lug style and with wider body, about 1-1/2", so that
stuff remains above the phenolic and can't sag towards the chassis.

600watt can be any form of voltage, it is a combined Voltage and AMP together to form a power of 600watt, you can't say it's fixed to 115V. 12VDC can light up a 600watt light bulb too.

All idiocy like this does is raise the bar further because everyone who

"presently" and what you did "years ago" are two different things. They
rely more on SAT scores now than they did before. The idiots are harder
to gauge now then ever before.

With the level of kids that have zero added education from their
parents, we'll be lucky if ANY of them actually learn the material.

It isn't college any more. It is advanced cheating classes. Half the
degreed assholes out there now do not really know the material.

One more reason why I do not get along well with "modern" youth.

The small stuff DOES MATTER.

Stop spitting everywhere. This isn't a baseball game, and you are not

Stop flicking your cigarette butt TRASH onto the world that belongs to

Stop throwing your fucking gum down on the ground, you fucking
