Question
A 3-phase transmission line has conductors 1.1 cm in diameter spaced 1 m apart in an equilateral formation. If a
current wave of 5 A travels along the line, and the line is connected at the end to a second transmission line with a
surge impedance of 460 S2, answer the following two questions:
If the resistance and leakance are negligible calculate the reflected phase voltage value (V)
Oa. 274 V
Ob. 249 V
Oc. 299 V
Od. 224 V
If the second transmission line has a resistance of 5 2 per km and a leakance of 1 μ S per km, and if the line is 50 km
long and is terminated at the end of the line by a 900 2 star connected load. Find the value of the reflected current
wave at the end of the line.
Oa. -0.5 A
Ob. -0.99 A
Oc. -0.79 A
Od. -0.63 A
