The length of a three-phase power transmission line with a nominal

operating voltage of 69 kV is 16km. Transmission line unit impedance per length is 0.125 + j0.4375 ohm / km. Power factor under 64 kV interphase voltage from the end of the line A 56 MW star-connected load with 0.8 reverse is fed. The line voltage of the transmission line is 69 kV capacity and power of the star connected capacitor to be placed as shunt to the load connected to the end of the line. calculate.
