Test: Effect of Earth on Three Phase Transmission Line Capacitance - Question 3

Which of the following situations is very useless when the series capacitors to the transmission line are of little use?

Detailed Solution for Test: Effect of Earth on Three Phase Transmission Line Capacitance - Question 3

Because capacitance is usually neglected for a small transmission line.

Test: Effect of Earth on Three Phase Transmission Line Capacitance - Question 4

It is intended to increase the power despatch of the existing transmission line. Then what can be the most appropriate solution for improving it?

Detailed Solution for Test: Effect of Earth on Three Phase Transmission Line Capacitance - Question 4

Series capacitors reduce the power as The solution for improving it is installing series capacitors

Test: Effect of Earth on Three Phase Transmission Line Capacitance - Question 5

When ______ then the transmission line will act as a distortion less line.

Detailed Solution for Test: Effect of Earth on Three Phase Transmission Line Capacitance - Question 5

When both the time constants become same, then the transmission will behave like distortion less line.

Test: Effect of Earth on Three Phase Transmission Line Capacitance - Question 6

The surge impedance of multiple conductor lines as compared to single line is _______

Detailed Solution for Test: Effect of Earth on Three Phase Transmission Line Capacitance - Question 6

Due to the reduced GMD, the impedance decreases and so the surge impedance.

Test: Effect of Earth on Three Phase Transmission Line Capacitance - Question 7

If the transmission line is lossless, then its characteristic will be _________

Detailed Solution for Test: Effect of Earth on Three Phase Transmission Line Capacitance - Question 7

The characteristic impedance for the lossless lines is given by √(L/C) because the resistance is zero.

Test: Effect of Earth on Three Phase Transmission Line Capacitance - Question 8

When the transmission line is lousy, then its characteristic impedance will not depend on which of the following?

Detailed Solution for Test: Effect of Earth on Three Phase Transmission Line Capacitance - Question 8

For a lousy line, the characteristic impedance will be independent of its sub synchronous frequency and length.

Test: Effect of Earth on Three Phase Transmission Line Capacitance - Question 9

Surge impedance of a transmission line is the impedance at the time of breakdown of voltage.

Detailed Solution for Test: Effect of Earth on Three Phase Transmission Line Capacitance - Question 9

Surge impedance is the characteristic impedance of a TL.

Test: Effect of Earth on Three Phase Transmission Line Capacitance - Question 10

Transmission efficiency of a transmission line increases with the _____________

Detailed Solution for Test: Effect of Earth on Three Phase Transmission Line Capacitance - Question 10

Increasing the power factor and voltage reduces the losses and hence improves the efficiency.
