Ferranti effect will not occur in case of which of following transmission lines:
- Short transmission lines
- Medium transmission lines
- Long transmission lines
- All of the above
Correct answer: 1. Short transmission lines
Explanation: The Ferranti effect is a phenomenon observed in long high-voltage transmission lines where the voltage at the receiving end is higher than the voltage at the sending end. This effect is mainly due to the distributed capacitance along the length of the line, causing capacitive voltage rise.
The Ferranti effect is more pronounced in long transmission lines, and it becomes less significant as the length of the transmission line decreases. Therefore, the Ferranti effect is not likely to occur or is negligible in short transmission lines.
So, the correct answer to the multiple-choice question is:
Short transmission lines
