I'm going through a list of 12 transformers and trying to determine if they are wye or delta. The schematics I have come across are for power engineering and don't go into too much detail other than the following:
The transformers step down ~400V 60Hz AC (three-phase) to ~120V 60Hz AC (single or three-phase) with one of the two schematic configurations:
1 - http://s8.postimage.org/66olvudat/transformer.png
2 - http://s8.postimage.org/edglnf3dh/transformer_4.png
I'm familiar with the first schematic drawing with two circles however this is my first time seeing four circles to represent a transformer; any ideas?
Thanks!
