The number of strands in case of ACSR conductor for 3 layer transmission line

Electrical Engineering MCQ

The number of strands in case of ACSR conductor for 3 layer transmission line:

1. 1
2. 7
3. 27
4. 19

Correct answer: 4. 19

Explanation:

Total number of strands N = 3x² – 3x + 1

Where, x = Number of layers = 3

Total number of strands N = 3×3² – 3×3 + 1 = 19
