Yeah I know

Just reading through some of these older threads while it's heavy raining and stormy outside.

A 33 kV pole fell over outside our depot and knocked all power out this morning with a large humm from the substation transformer.

Taking the brake magnet out will make the meter go faster.

I collect older electromechanical kWh meters and when I was younger I liked to see the dials move faster too to watch numbers click over to 1000 or 10000 etc, so by removing the magnet and put the low load adjuster to + or fast the meter will creep even with no load at all.

Can anyone send pictures of these lamps? I really like the idea of that it must look really cool! I would like to build something like that actually!
A.D

the "A" base meters make nicer lamps. they have a built in terminal board unlike the "S" type which are designed for socket mounting.check out ebay under WATTHOUR.there usually a couple listed.or ClASSIC METERS .COM they have some really nice ones already made.you can use everything from a GE I-14-A to an I-50-A. the best one to get is a 5 or10 amp meter.usualy found in the above models.occasionally a CA westinghouse shows up but mostly 15 amp versions.

"Got it working. I took off the magnets and now it spins about 4 RPM no load and about 44 RPM with a 100 W bulb."

For the "authentic" look, get the magnet demagnetized and re-attach it. Or install a magnetic shunt across it so that the flux fields are bypassed around the disk rather than through it.

"so, if removing the magnets makes it go faster than adding magnets must .... never mind, but i'm guessing you don't need those magnets anymore, so you can send them to me. I'll put them to good use "

Right! But adding magnets the wrong way can subtract from the damping magnet and make it run faster.

The lower the Kh on the nameplate, the better. The Kh is the amount of energy required to turn the disk one revolution. So, for a given load, a Kh of 3.6 will turn twice as fast as a Kh of 7.2.

Kinda on the same topic, I have an electronic ABB meter on my sound system rack to monitor usage.

Following specs:

Type A1D+
Form 2S
CL200
KH 1.2
P/R 24
TA 30A
120-480v, 3w, 60Hz

Can anyone tell me how to, or point out a website, showing how to re-program this meter? So far I've had no luck in finding out anything about this meter.

I would like to reset the grand total usage, program in my kwh/h rate and reset Kh to 1.0 or maybe even 0.5

And to any poco guys wondering, it won't work on my apartment's service, we have the old "A" type hardwired meters.

Not that I'm in any way challenging honesty, but nobody (POCO's or manufactureres) wants anyone getting the programming for the very reasons you're stating.

Nice job Rabbit.
