State the impact of inductance and resistance on transmission line performance

State the impact of inductance and resistance on transmission line performance
by

1 Answer

Answer :

Impact of inductance on transmission line:

1) It causes IXL drop in transmission line which affects regulation.

2) It is the only parameter which decides power transmission capacity of line i.e. if inductance decreases power transmission capacity increases.

Impact of resistance on transmission line:

1) It causes voltage drop, so it affects regulation.

2) It causes I2R loss which affects efficiency and temperature rise.

3) Whatever power loss occurs in transmission line is only due resistive parameter.

4) Though value of resistance is very small, it causes losses, temperature rise& poor voltage regulation so it cannot be neglected
