What does this piece of switchgear do?

[Flanders]

Is it a toaster for giants?

 

[tazz]

At a guess, I would say a generator syncro.....when gennie gets up to speed, this switches the gennie into the building supply.

Big clue:

I'll go along with my first choice a wound rotor speed control, resister bank, OR a load bank for a gen-set which would be my second choice.

 

[tazz]

Second photo does look like a 3 phase wire wound variable resistor

 

[SJD]

Some kind of stage lighting controller / dimmer, but no idea exactly what?

 

[Lucien Nunes]

There are three wiirewound rheostats, yes, and they operate in 'phases' of a sort, but not phases of the supply.

Ive looked at it hard and long and


nothings come into my head. Its a conundrum....

 

[ian.settle1]

Load test bank by any chance

Is it a variac

I keep looking at the pic, no idea.? Bike chain made up rig I take it.?

 

[tazz]

If the electric motor is constantly running, the arms would be changing the output voltage constantly, or its waveform. So next guess is converting voltage & frequency...?

I thought it was phase converter or Automatic regulator of some sort, but then Lucien said what ever it does takes a minute, and that it is SP in/ SP out.

I was thinking along similar lines. Is there a pony motor connected to the chains which allows the user to speed up/slow down the main motor.

Combine my clue in post #23 with SJD's post #26...
