Is the Delta current <30 degrees or not?

  1. Oct 24, 2015 #1
    The internet is really nebulous sometimes, I was looking and couldn't find the answer. I know that the line voltage is √3*Vphase<30degrees
    for a WYE.

    and that line current = √3*Iphase
    for a delta connection. But is that line current 30 degrees out of phase to the phase current?
    As the voltage is in the WYE case.

    Yes, the line current lag by 30 degree to the phase current.

    Ah, ok thanks.

    P.S. actually, since you said lag does that mean <-30 deg?
    (negative thirty degrees)

    Yes that's what I meant.
    Line current= sqrt(3)* phase current <-30
