    A basic formula is P=IE*1.73.

    P= Power
    I= Amperage
    E= Voltage
    1.73= 3 phase constant

    Once you arrive at the actual total 3 phase power, increase by 25 % to size the transformer.

    What exactly are you trying to do?

    Distribution transformer??
    How are you going to convert single phase into 3-phase using a transformer?

    Besides, this is FAR beyond the scope of DIY work. If you have to ask questions like this you should NOT be working on such things.
