A 320-km 500-kV, 60-Hz three-phase uncompensated line has a positive-sequence

series reactance x = 0.34 2/km and a positive-sequence shunt admittance y = j4.5 x

10-6 S/km. Neglecting losses, calculate: (a) Ze, (b) (yl), (c) the ABCD parameters,

(d) the wavelength of the line, in kilometers, and (e) the surge impedance loading

in MW.

Determine the equivalent n circuit for the line in Problem 5.26.
