Question
Example: A three-phase
ring nein ABCD, fed from
end A, supplies balanced load of 50A at 0.8,pf lagging
at B, 120 at 0pf at a and at 0.866 pf lagging at
D, the load currents being referred to the voltage
point A. Determine the currents in various sections.
if the impedance per phase at each section is:
A B = 1+j0.6ohms, BC = 1.2+j0.9homs, CD = 0.8+j0.5ohms and
DA= 3+j2homs
