Which of the following is not a valid advantage of bundle conductor?

(A) Reduced reactance

(B) Reduced voltage gradient

(C) Reduced corona loss

(D) Increased reactance


Answer: (D) Increased reactance


Explanation:

Bundled conductor are those conductors which form from two or more stranded conductors, bundled together to get more current carrying capacity.

By using bundle conductors instead of the single conductor in the transmission line increases the GMR of the conductors.



Advantages of Bundled Conductors:

Bundling of conductors leads to a reduction in line inductance.

Bundling of conductors leads to increases in capacitance.

An important advantage of bundled conductors is their ability to reduce corona discharge

Reduction in the formation of corona discharge leads to less power loss and hence improved transmission efficiency of the line.

Reduction in communication line interference.
