Did I miss something? Did this forum get renamed the home work help line?
Oh well what they heck, insomnia is a cruel mistris. First, I think you need more than one transformer. So your source is 380V, You ain't from round here are ya?.
I'll help you out with one of them to get you started and let the other guys in the forum answer the others (they get real jealous if you don't share). I'll start with #3, you need a 0 kva xfmr or a few pieces of wire to connect your load to your source.
