A balanced A-connected load consisting of a pure resistances of 18 Q per phase is in parallel with a purely resistive balanced Y-connected load of 12 Q per phase as shown in Figure 2.26. The combination is connected to a threephase balanced supply of 346.41-V rms (line-to-line) via a three- phase line having an inductive reactance of j3 Q per phase. Taking the phase voltage Van as reference, determine (a) The current, real power, and reactive power drawn from the supply. (b) The line-to-neutral and the line-to-line voltage of phase a at the combined load terminals.
