Question:

Rated line voltage is applied to the sending end of the line in Problem 5.26. Calculate the receiving-end voltage when the receiving end is terminated by

(a) an open circuit,

(b) the surge impedance of the line, and

(c) one-half of the surge impedance.

(d) Also calculate the theoretical maximum real power that the line can deliver when rated voltage is applied to both ends of the line.

Problem 5.26

A $350 - k m, 500 - k V, 60 - H z$ , three-phase uncompensated line has a positivesequence series reactance $x = 0.34 Ω / k m$ and a positive-sequence shunt admittance $y = j 4.5 \times 10^{- 6} S / k m$ . Neglecting losses.
