I have an unusual transformer (see picture) This is an Allis-Chalmers 150 KVA Dry Type transformer there are two visible coils and the drawing appeas to be a T. This is 3 phase 480 VAC to 208/120 VAC. There was an issue with the output voltage and just trying to get some information. Any help would be appreciated.
We plan to megger and TTR the transformer.
From what I see A and C are derived from one coil and the neutral and B phase from a sperate coil.
