The length of transmission line which will be more impacted by the Ferranti effect is | Power Transmission and Distribution MCQ#53
The length of transmission line which will be more impacted by the Ferranti effect:
- 100 km
- 200 km
- 350 km
- 499 km
Correct answer: 4. 499 km
The longer the transmission lines are, the more is the capacitance is, and the higher the capacitance is, the more is the Ferranti effect.
Ferranti effect is defined as the increase in voltage at the receiving end of lines. This rise in voltage along the line occurs due to the capacitive current of the line flowing through the line inductance.
