Question

Consider the following statements:
1. By using bundled conductors in an overhead line, the corona loss is reduced
2. By using bundled conductors, the inductance of transmission line increases and capacitance reduces
3. Corona loss causes interference in adjoining communication lines
Which of these statements are correct?

• A. 1 and 2
• B. 2 and 3
• C. 1 and 3
• D. 1, 2 and 3

Hint:

Bundled conductors reduce corona loss and radio interference.

Answer 1

The Correct Option is C

- Statement 1: Bundled conductors reduce the voltage gradient on the conductor surface, thereby reducing corona loss.
- Statement 2: Actually, bundling reduces inductance and increases capacitance—so this is incorrect.
- Statement 3: Corona loss can indeed lead to radio interference.
