A 345-kV three-phase line is 130 km long. The resistance per phase is 0.036W per km and the inductance per phase is 0.8 mH per km. The shunt capacitance is 0.0112 m F per km. The receiving end load is 270 MVA with 0.8 power factor lagging at 325 kV. Use the medium line model to find the voltage and power at the sending end and the voltage regulation.
