    The line current is SQRT(3) times the phase current and is 30 degrees behind. The exact opposite for the line/phase voltage in the Y connection. Do you have the Stevenson's Power System book? (1994) In chapter 1 section 1.8 you will find two really good phasor diagrams. Once you see them you...

    L/L fault question

    My mistake was that I used the wrong value (0.2p.u.) for the generator's Z+. I wonder if you really need to make any calculation at all?
