About that 46-30 genset

Here is some read material that should help........

I'll be damned.....they loaded in the order I wanted them posted!!!!!!!!!!

Great timing for this question, 2 weeks ago I picked up a D311 genset I bought, I had a discusson with the seller about current quality with some of the lower quality generators as he was upgrading to a Modern unit. Little did I know he had a electronic background. After our discussion he hooked up a Scope to the old cat and took readings at light and moderate loads, then he did the same with his New generator and his public utility, He found the Old cat I bought had a cleaner sine wave than the other 2 sources and held the frequency closer than the New generator. lucky for me he was tired of difficult pony engines.

I worked an Allis like that 20 plus years ago, it had an electric stepper motor drive on the Rheostat to turn up the exciter voltage!

That Power-Tronics looks like a WEALTH of information on the Tech page!

I was digging around on the shelves in my shop the other day and found a Basler Voltage Regulator that I forgot I had?

My genset dosent look th same as the one posted by Old Magnet.
It does have the belt drive exciter on the top but I dont see any place on it for the other parts.
The main breaker has a date code of 1942 if I read it right.
Looks identical to the ones in the sales flyers from that time.
I will attempt pics and give the serial amd model numbers.
Thanks Chris

Didn't expect it to look the same (it is a later model) but ought to be similar in function, at least enough to determine how it works as per your question.

I forgot to mention that mine is set up as single phase 120/240.
Came with a 125 amp breaker and a 250 amp switch.
Was originally configured that way...ran a lighthouse from new.
Thanks Chris

A generator set ordered for a specific load like the lighthouse may have not needed much in the way of automatic voltage regulation. Consistent load, has to run reliably, every night, all night, so part count and failure modes would favor a simple voltage control system. Perhaps only a rheostat to change the resistance in the field circuit.

I have a 1944 model Buda set with both automatic (via a Reg-Ohm mechanical regulator) and manual via the rheostat. I don't think most folks had a lot of faith in the reliablity of the electrical controls at that time. With the D4600, if worse came to worst, a can of gasoline and a starting rope would get the lights on.
