A 3-phase line has a series impedance of 300 78° ohms per phase and a shunt admittance of 24 x 10* 90° siemens per phase. The voltage at the receiving end is 220 kV but there is no load at receiving end. A load of 100 MW at unity p.f. is connected at the mid point of the line. Using nominal circuit find sending end voltage. A 3-phase line has a series impedance of 300 78° ohms per phase and a shunt admittance of 24 x 10* 90° siemens per phase.
