Question
Three unequal single-phase loads are
connected across the lines of a balanced, 3-
phase, 230 volts (line) circuit. The first load
takes 106 A at 0.78 pf lagging and is
connected across lines 1 & 2. The second load
takes 142 A, at 0.82 pf lagging and is
connected across 2 & 3. The third one takes a
load of 28.4 kW at 0.77 pf lagging. Solve for
the following
a. The line currents
b.The equivalent wye connected impedance of
the connection
c. The total complex power absorbed by the
load
