Resistance grounding is used for voltage between_________________?
Correct answer: C. 3.3kVandllkV
- A. 33kVto66kV
- B. HkVto33kV
- C. 3.3kVandllkV
- D. none of the above
Explanation
Resistance grounding is commonly applied to medium-voltage systems, particularly around 3.3 kV to 11 kV, to limit earth-fault current and reduce damage. The 3.3 kV to 11 kV range therefore matches option c.
