Bundled conductors in EHV transmission lines help in

A. Decrease capacitance
B. Decrease Inductance
C. Increase capacitance
D. Increase inductance

Answer: B. Decrease Inductance

Explanation:


Total inductance is given as L = 2*10-7 * ln(d/r’)

A bundle conductor is a conductor made up of two or more sub-conductors and If we use bundled conductors, the effective radius will increase hence increase in radius will decrease the inductance.

Bundled conductor Primarily used to reduce the potential gradient on the surface of the conductors so that occurrence of Corona can be reduced.

It helps in obtaining better voltage regulation and efficiency by reducing the inductance and skin effect present in the power lines.
