Electrical Engineering MCQ on Power Transmission
One of the demerits of a ‘constant voltage transmission system’ is
- Availability of steady voltage at all loads at the line terminals
- Improvement of power factor at times of moderate and heavy loads
- Increase of short-circuit current of the system
- Possibility of better protection for the line due to possible use of higher terminal reactants
Correct answer: 3. Increase of short-circuit current of the system
