A three-phase 20 kV medium-voltage line is 10 km. Resistance is 0.365 2/km and
reactance is 0.363 2/km (inductive). Voltage at the beginning of line is 20.5 kV. At the
end of the line is loading P= 800 kW with power factor 0.95ind. Draw 1-phase equivalent
diagram and calculate load current, line voltage at the end the of line, voltage drop and
power losses of the line.
