In the figure above, two balanced 3-phase delta and star-connected loads are connected in parallel to a
balanced three-phase power distribution line. Delta and star connected loads are completely resistive and
the resistance values per phase are 18 2 and 12 22, respectively. The phase-to-phase voltage value of the
source feeding the line is 346.41 V (rms), and it is assumed that the three-phase network between the source
and the load has an inductive reactance value of 3j 2 per phase.
a-) Find the total current drawn from the source, active and reactive power values by selecting the
Van voltage as a reference value.
