    Calculating phase currents from line currents in an unbalanced delta

    yes, I don't know the difference impedances of the different phases. In polar form, I assumed Ia< 0°, for here I can calculate the angles of Ib and Ic (given that their sum is 0). Given IA = iac - iba IB = iba -icb IC = icb - iacthe phases voltages should be in line with the phase currents, so...

    Calculating phase currents from line currents in an unbalanced delta

    Given these conventions I tried to calculate iba and icb. But I seem to have taken a wrong step somewhere as my end result is incorrect. I think its already in the first steps: iba|IA=0 = IB +icb iba|IB=0 = iac - IA += IB +icb + iac - IA icb|IA=0 = iba -IB icb|IB=0 = IC - iac -> -IA -IB - iac...

    Calculating phase currents from line currents in an unbalanced delta

    In an unbalanced delta system, I can calculate the line currents given the phase currents. However, I seem to be unable to go the other direction and cannot find sufficient resources to do so. Looking at the phasor diagrams it seems like this should be possible, but my math (or understanding of...
