Problem 1.12: A balanced Y-connected Load-1 has Z
LN1
= 4 + j 1 Ω in each
phase of Y. It is connected in parallel with a balanced Δ-connected Load-2
with Z
LL2
= 12 + j 6 Ω in each phase of Δ. If these two parallel loads are
powered by a 3-phase, Y-connected generator with 480 V line voltage,
determine the line current at the generator terminals and the real power
delivered by the generator.
