Maximum power transfer capability of transmission line can be increased by using

Maximum power transfer capability of transmission line can be increased by using:

1. Bundled conductors
2. Parallel transmission lines
3. Series capacitance
4. All of these

Correct answer: 4. All of these

Explanation:

1. Bundled conductors: Bundled conductors involve grouping multiple conductors together, typically in the form of a single transmission line. This configuration increases the effective surface area for heat dissipation and reduces the electrical field gradient between conductors. As a result, bundled conductors can enhance the power transfer capability of a transmission line.
2. Parallel transmission lines: While parallel transmission lines may not directly increase the power transfer capability of a single line, they can collectively enhance the overall capacity and reliability of the transmission system.
3. Series capacitance: Although series capacitance is not commonly used for increasing power transfer capability, it can be employed to modify the electrical characteristics of the transmission line, potentially improving its performance under certain conditions.
