Repeat Problem 11.34 if the loads are converted to an equivalent wye. Compare the results of both problems.
Problem 11.34
A balanced three-phase system has a balanced wye load in parallel with a balanced delta load. If the source is a balanced wye connection with a positive phase sequence and the phase voltage V an =200 30° V, determine the line currents when the load impedances, Z = 50 + j 70 and Z Y = 15 + j 30 , are converted to an equivalent delta.
