For transmission of power over a distance of 500 km, the transmission voltage should be in the range?
Correct answer: A. 150 to 220 kV
- A. 150 to 220 kV
- B. 100 to 120 kV
- C. 60 to 100 kV
- D. 20 to 50 kV
Explanation
A 500 km transmission line is a long-distance line and commonly operates at an extra-high voltage around 220 kV, fitting the 150 to 220 kV range. Higher voltage reduces current and therefore limits transmission losses and conductor size.
