One of my customers is cleaning their warehouse. They have a mint condition Allis-Chalmers 79.5 KVA dry transformer 450-480 Pri. 120-208 Y Sec. Since A-C went out of business in the early 1990, this must be 30-50 years old. Anyone know when they made dry transformers. Hate to see it go in the scrap pile but too big for me to store.
I am sure it said 79.5 ( I agree its not a standard value) I will try to photograph the nameplate Friday when I return. It has been installed. Clarify mint or maybe real good, no rust, good paint, little scratches or dents. Has a pigtail (Greenfield) hanging on it. It does have impedance on the nameplate. I assume copper, but will also check that. The primary has multiple taps (fixed Sec) The owner was not sure of its history, but the location of much of the other equipment (Printing) in the lot came out of a bldg that was formally a Home Depot. (One of the first in Houston) That was later a printing (Screen) plant.
IMHO, being 'used' will effect the value a lot for a reseller. KOs indicate 'used' a pigtail shout it.
'Used' and 'old' will really hurt.
I had a 300KVA, 4160 to 120/208, delta/y, dry, Challenger that was new, installed for 9 days, taken out of service, and it sat at my shop for 5 years! I still had the factory paperwork, bill of laden, etc. Could not get a dime for it.
It was Al windings, so the scrap value was squat; I wound up putting it in a dumpsterwhen I moved and started to close shop.
