The minimum clearance between the ground and a 220 kV line is about_________________?
Correct answer: C. 7.0 m
- A. 4.3 m
- B. 5.5 m
- C. 7.0 m
- D. 10.5 m
Explanation
Higher-voltage lines need greater ground clearance for safety and to prevent flashover during normal operation or voltage surges. For a 220 kV line, the approximate minimum clearance is 7 m.
