Problem 3: Three loads are supplied by a voltage source, Vs, through a line. The
given are as follows:
L1 = 60W @ 0.8 LAG
L2 = 40W @ 0.5 LEAD
ZLINE = 0.5 + j0.5 Q
V, = 5040
S. = 200VA @ 0.75 LAG
Find:
1. The complex power associated with Load 3
2. The impedance (Z3) of Load 3
3. The KVAR rating of the capacitor to be connected parallel to the loads that will raise
the PF to unity.
