Question:
Bundled conductors are mainly used in high voltage overhead transmission lines to _______.
Bundled conductors are mainly used in high voltage overhead transmission lines to _______.
Show Hint
Bundled conductors reduce electric field intensity, minimizing corona discharge and noise in EHV lines.
Updated On: Jun 24, 2025
- reduce transmission line losses.
- increase mechanical strength of the line.
- reduce corona.
- reduce sag
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Role of bundled conductors
Bundled conductors are used in EHV systems to reduce the electric field intensity at the conductor surface.
Step 2: Effect on corona discharge
Corona loss is directly related to the surface voltage gradient. Bundling increases the effective radius, reducing this gradient and hence corona.
