Which of the following is not a valid advantage of bundle conductor?a)...
Increased Reactance
Reduced reactance, reduced voltage gradient, and reduced corona loss are all valid advantages of bundle conductors. However, increased reactance is not a valid advantage.
Explanation:
- Reduced Reactance: Bundle conductors have a lower reactance compared to a single conductor, which helps in improving the overall efficiency of the transmission line by reducing power losses.
- Reduced Voltage Gradient: Bundle conductors help in reducing the voltage gradient along the transmission line, which can help in maintaining a more stable voltage profile and reducing the risk of voltage surges.
- Reduced Corona Loss: Corona discharge occurs when the electric field strength exceeds a certain threshold, leading to power loss. Bundle conductors can help in reducing corona loss by distributing the electric field over a larger surface area.
- Increased Reactance: This is not a valid advantage of bundle conductors. Increasing reactance could lead to higher power losses and reduced efficiency in the transmission line.
In conclusion, bundle conductors offer several advantages such as reduced reactance, reduced voltage gradient, and reduced corona loss, making them a preferred choice for high voltage transmission lines.

Which of the following is not a valid advantage of bundle conductor?a)...
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.
So, inductance reduces according to the following equation
Hence, the inductance per phase of the conductor decreases
So, capacitance increases according to the following equation
Hence, by using bundle conductors GMR is increased, so inductance L decreases and capacitance C increases.
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.
