The spacing between phase conductors of a 220 kV line is approximately equal to________________?
Correct answer: C. 6 m
- A. 2 m
- B. 3.5 m
- C. 6 m
- D. 8.5 m
Explanation
A 220 kV overhead line requires wider phase spacing to withstand its higher electric stress and limit flashover risk. A spacing of about 6 m is the conventional approximate value among these choices.
