I am trying to locate parts to build a coil from a 1937 article I have.
Does anyone know where I can obtain an old pole transformer, 4400 V
to 120 V 5 KVA?
This was common for houses back then but impossible to find so far.
You might also find them as a "dry transformer" used in industrial
plants fed with 2400 or 4160 V to make 120V for lighting and light appliances.
For instance, at the bottom of this list
there's a 5 kVA 4160 to 240/120V single phase transformer.
I'd imagine there's tons of 4160 to 120V transformers around.. 4160
is a very common MV distribution voltage (at JPL, I think most of the
"substation" to "building" distribution is done at 4160) You'll see
120V secondaries because they use 3 in Wye to make 208/120 three phase.
I do not want a modern higher voltage transformer as I do not need
higher current, voltage or size.
