Question 1) A 154 kV transmission line has a length of 100 km. The line and the conductors are given in Figure 1. The line is operated at f= 50 Hz. For both old and new lines calculate; a. GMD and GMR. b. Inductance of the line in Henries (H). c. Series Impedance (Z) of the line in Ohms. d. *Compare the results for both lines and comment on the results. e. *If the distance between the two neighbouring conductors is increase from 13 meters to 15 meters what would be the parameters in part a.,b. and c. comment on the results. 13 m New Line's Conductors 13 m Old Line's Conductors r = 2 cm d = 40 cm r 2 cm Figure 1
