Three phase Y-Y connected systems

I have a question regarding determining values like line voltage, phase current etc for a three-phase Y-Y Connected system given a few parameters. Unfortunately I cannot find any good examples in my text book to follow and the notes from class we talk about their set up but never went over any examples in solving for different values. Does anyone know of a good example/resource that i can look over?.

For specifics we are given 480 line-to-line voltage @60HZ. Its per Phase load is 300mH inductor connected in series with 250 ohm resister. Determine line voltage,phase current, total real power, reactive power, apparent power and power factor.
