If the load on the line described in Prob. 6.14 is 80 M\V at 220 kV, with unity power factor, calculate the current, voltage, and power at the sending end. Assume that the sending-end voltage is held constant and calculate the voltage regulation of the line for the load specified above.
Prob. 6.14
A three-phase, 60-Hz transmission line is 250 mi long. The voltage at the sending end is 220 kV. The parameters of the line arc R = 0.2 Ω/mi, X = 0 .8 Ω/mi, and Y = 5.3, μS/mi. Find the sending- end current when there is no load on the line.
