new guy here with an, judging fromt the other posts i have read, easy question.
My electrical history is limited. I worked on the electrical systems of the huey and cobra helicopter in the marines but now i am working as a PLC tech in the modern industry and i am somewhat the quasi electrician here. I am comfortable with household wiring, installing 480V motors and vfd's among other things. The ground i have yet to tread is transformers. I am installing a 3 phase transformer. 480V in and 120/240 out. i will get some more information for you momentarily but where can i start as far as connections go? From what i am told, i need a single leg of 240V out.
Back with the new info. It is an ACME Transformer Cat. No. T-3-53341-1S
I found this diagram as well. Is this correct?
I am thinking it should be wired like this.
Then X1, X2, and X3 are my three phases of 240? Each one will give me 240 to ground?
To take this even further, I am going into a VFD after the transformer to give me 220V 50Hz. The VFD accepts single or three phase 240. I am guessing thats 2 or 3 legs of 120?
