Constant voltage transmission entails the following disadvantage?
Correct answer: B. short-circuit current of the system is increased
- A. large conductor area is required for same power transmission
- B. short-circuit current of the system is increased
- C. either of the above
- D. none of the above
Explanation
In constant-voltage transmission, a fault can produce a large current because the system voltage remains nearly fixed while the line impedance is low. A larger conductor area is not the disadvantage, since higher voltage normally reduces current for the same power.
