A 275kV, 50HZ three-phase transmission line is 110 km long. The line is supplying a three-phase load of 280MVA at 0.85 pf lagging at 275kV. The line comprises the following characteristics per-phase, resistance 0.0350/km, inductance 0.85mH/km and capacitance 0.0112 pF/km. i. Calculate the sending end voltage based on ABCD constant of the transmission line (T- network). ii. Determine the voltage regulation.
