Exercise 19

An abc -phase-sequence three-phase balanced wye-connected source supplies a balanced delta-connected load. The impedance per phase of the delta load is 10 + j 8 . If the line impedance is zero and the line current in the a phase is known to be I aA = 28.10 28.66° A rms, find the load voltage V AB.
