If the separation between the three phase of a transmission line is in...
Explanation:
Increasing the separation between the three phases of a transmission line results in a change in the line parameters, including inductance and capacitance. The inductance will increase, while the capacitance will decrease. This is due to the increase in the distance between the conductors, which results in a longer path for the magnetic field to flow, thereby increasing the inductance. On the other hand, the increase in distance between the conductors also reduces the electric field between them, resulting in a decrease in capacitance.
Inductance and Capacitance in Transmission Lines:
Transmission lines have inductance and capacitance per unit length. Inductance is caused by the magnetic field around the conductors, while capacitance is caused by the electric field between the conductors. The inductance and capacitance of a transmission line depend on the geometry of the conductors, such as their size and shape, and the distance between them.
Effect of Separation on Inductance:
The separation between the conductors of a transmission line affects the inductance of the line. When the distance between the conductors is increased, the magnetic field around each conductor has a longer path to follow, resulting in an increase in inductance. The increase in inductance results in a higher impedance for the line and a slower propagation of the wave along the line.
Effect of Separation on Capacitance:
The separation between the conductors of a transmission line also affects the capacitance of the line. When the distance between the conductors is increased, the electric field between them is reduced, resulting in a decrease in capacitance. The decrease in capacitance results in a lower characteristic impedance for the line and a faster propagation of the wave along the line.
Conclusion:
In conclusion, the separation between the three phases of a transmission line affects the inductance and capacitance of the line. Increasing the separation between the conductors results in an increase in inductance and a decrease in capacitance. This change in the line parameters affects the characteristic impedance and propagation velocity of the wave along the line.

If the separation between the three phase of a transmission line is in...
Inductance is propotional to log of the distance between cables for a three phase system . Since this distance will increase on increasing the separation between cables , Inductance will increase .
Similarly by formula Capacitance is inversely proportional to the log of (D/r) and hence as D is increased , Capacitance has to decrease .
Increase in inductance with increase in distance doesn't seems logical , but If you understand the real approach , It will make more sense , When you bring two conductor closer , both will cancel out their inductances and hence the inductance will become lesser . When you make them apart ,their flux will have more area between them , and they will not cancel out as much as in prv cases . hence It will increase then previous values .
