A 69 – kV, 3 – phase short transmission line is 16 km long. The line has a per phase series impedance of 1.125 + j0.4375 ohm per km. Shunt capacitors are installed at the receiving end to improve the line performance. The line delivers 70 MVA, 0.80 lagging power factor at 64 kV. Determine the receiving end line MVAr when the sending end voltage is 69 kV.
