Electrical Engineering MCQ on Power Transmission
The total diameter of a three-layer ACSR conductor is 5 cm. The diameter of each strand will be
- 1 cm
- 1.5 cm
- 5.5 cm
- 6.8 cm
Correct answer: 1. 1 cm
Explanation:
Mathematical formula for total diameter of an ACSR conductor D = (2x-1)*d
Where in above equation
- D =Total diameter
- x = Number of layers
- d = diameter of each strand
Therefore,
5 = (2*3-1)*d
d = 1 cm
