No argument about the utility keeping their museum piece, Dave...one less thing to deal with. They are likely hard up for spares.

On the label, it seems to list “250/500/?10?” for the secondary. Do you know what the “?10?” is?

One comment on the odd terminal layout...it may have allowed for easier {maybe drilled busbar} jumper/strapping for assorted voltages. Note the terminal dissymmetry on the high side too.

Look at all this Legacy Equipment!!!

Bulldog EXO Disconnect (Vac-U-Break), an old Square D EXO, An old (looks like) FPE EXO, and for jollies, a newer Square D EXO!

Last time I saw Multipole Knife Switches and Non-Deadfront gear was 1982! In the highrise area of Downtown Los Angeles, we were doing another "Active Branch Remodel" on a Great Western Savings branch that was located on the ground floor of an 11 story Building.
Building was near 4th and Hill in Downtown LA.
Must have been built between 1920's and early 1930's.

Had gear that looked exactly like the stuff shown in these images!!!

All Conductors were copper and had the same type R Insulation, all tied down with the cloth weaved thread lacing method. All live stuff exposed. system Voltage: 440 VAC 3Ø 3W.
Scary, but inspiring!

That Transformer should go to the Smithsonian Institute!!! G.E. circa 1902-1908!!! If it was a Westinghouse brand, I would say that Nik Tesla wound the thing himself!!!
Very interesting nameplate data, too!

Even that Transformer under the Disconnects is from the Jurassic Period! What's up with it, did it catch fire and burn other stuff, or did other stuff burn it?

There was a similar old Transformer around here, but a runaway Brontosaurus stepped on it and smashed it flat! Took the smashed Xformer to Mr. Slate's Gravel Quarry/Metal Recycle center and sold it for scrap. Fred Flinstone took most of the money, though!
< [Linked Image] >

On the serious side, that looks like one heck of a job just to demo out all the post Triassic equipment!

Good luck!

Hi Guys,

Not a clue! When I asked the POCO transformer guy, he said "Don't know".

The little transformer is still connected and in use until we replace it with the new one. As a matter of fact, the big one is still providing power to the complex through our temp service drop and switchgear.

I'll be willing to bet the POCO won't even touch the big one once we hook-up to the new pole mounted ones with the new service.

We will insist that they remove all load side wiring outside!

I darkened the contrast on my monitor and that transformer label looks like it says 3250/500/240. The 3 is faint compared to the 250.
