Transformer Bank in an Alley

It's all in the details.

Wonder if I should snip the secondary center taps...? I’ll bet MikeCT could tell me! Just thought I’d use them since they were on there. Northbrook Edison could give them a lighting transformer in the basement instead. Hmm.

Very nice work. period correct too.

as always your work is exceptional

Outstanding build Norm.

Terrific work.  Didn't even need to look at the poster's name to know.

The only thing missing is the hmmmmm

Thx guys. We have a lot of machines to run! I have another batch to paint up too.

Old, Delta/Delta transformer banks were usually, 3 wires High voltage, and 3 wires Low voltage. There was no common neutral connection, noted,  Y Primary, Y Secondary, transformer bank wiring, common today.  Secondary, One from each transformer, 240 volt three phase, 3 wire, purpose was three phase motor loads.  You might see a fourth wire from one of the transformer secondaries, as a center neutral tap for 120 volts.  This 4 wire power feed, in a three phase panel, was usually marked, only two of the three phase wires would yield 120 volts.  The third, (high leg), was a much higher, and unpredictable voltage, plus or minus 185.  

Excellent, thanks a lot Mike! I knew you would know! 

I thought your third pic was of a full scale scene until I spotted the third rail.  Very nice work.

Norm - I like it a lot!

Nice!

Very nice work Norm, thanks for sharing, I really like the details.

Impressive, as usual.

Thx guys. Dave, the transformers and the spool insulators are Keil Line parts (item #48-133). They were sold as a set of two transformers along with the insulators and a bunch of assorted hardware. Scale City is selling the transformers now but I’m not sure they have them as part of the set Keil used to offer. The raw build photo on my bench is the most comprehensive one I have, the other ones show incorrect wiring on the primaries, oops. The rest of the materials came out of my scrap bins.

Sorry Dave I totally spaced that out. I’m not sure who made the majority of those white metal castings. I believe I got those from Ed Rappe on eBay. Here’s another batch I’m working on from eBay:

Very impressive!

Norm,

Details, Details, Awesomeness...

Looks fantastic Norm. What book did you use as a reference?

One of the books I got from the shop you took me to in St. Paul:

Nice to hear from you Brother!

This really looks great Norm. That book is a great reference.

Thx guys. Someday I'll model this:

Anyone recognize it?

Sure...  It's next to where we use to park our RV adjacent to the Blue Hall!...York, PA!!!

Sigh!

Is there one down there too? This one is over by Orange Hall. I always wanted to model it!
