5.26 A 350-km, 500-kV, 60-Hz, three-phase uncompensated line has a positive-sequence series reactance x = 0.34 N/km and a positive-sequence shunt admittance y = j 4.5 × 10-6 S/km. Neglecting

losses, calculate: (a) Z.(b) yl, (c) the ABCD parameters, (d) the wavelength A of the line in kilo-meters, and (e) the surge impedance loading in MW.
