I believe that I have a three phase delta to single phase transformer 1Kva with input 415 v three phase and output 230 Vac single phase. ( Someone help me to identify what kind of transformer is this?)
I would like to test the transformer. What would happen if inject a 230 vac from a socket directly to the secondary of the transformer? Would I damage the transformer or it's perfectly fine and I would get the 415 v ac at the primary end. I'm just worried the sudden surge of voltage to the terminal may effect the transformer wingdings.
Below is the sample picture what I'm trying to do: (please ignore the immature wiring connection and the exposed fuse)
Some part of me saying this is a bad idea. What would happen and why is the question now?
Edit: Primary connections: Secondary Connection:
