A three-phase transmission line is 300 mi long and serves a load of 400 MVA, with0.8 lagging power factor at 345 kV. The ABCD constants of the line are A=D=0.8180

/ 1.3^{\circ} B=172.2 / 84.2^{\circ} \Omega C=0.001933 / 90.4^{\circ} \mathrm{S} (a) Determine the sending-end line-to-neutral voltage, the sending-end current,and the percent voltage drop at full load. (b) Determine the receiving-end line-to-neutral voltage at no load, the sending-end current at no load. and the voltage regulation.
