T1c = 3 phase Delta pri. to 3 ph 4 wire Wye secondary - shielded transformer.
Note white wires running into coils for shields.
I thought that everyone would enjoy some pictures I shot recently of some special duty transformers [just the cores/coils - no enclosures].
This one is a 200 KVA 3 phase Delta to 3 phase 4 wire Wye - with shielded windings, along with grounded core.
The small white wires run to the shields.
The large white wires on the fronts of the coils are the % voltage taps
