Bundled conductors are mainly used in high voltage overhead transmission lines to

  • A. Reduce line loss
  • B. Reduce harmonics
  • C. Reduce corona
  • D. Increase strength

Answer: C. Reduce corona

Explanation: Bundling conductors increases the effective conductor radius (GMR), lowering surface electrical field gradient, which significantly reduces corona loss and audible/radio interference.
