Answer 2

Answer:

Maximum power transfer capability of a transmission line can be increased by either increasing the voltage level or reducing the line reactance value.

Explanation:

The objective of any electrical power transmission system is power transmission with minimum loss and maximum power transfer capability with voltage regulation.

• Maximum power of a transmission line is given by

       $P_{max} =\dfrac{V_SV_R}{X_L}$

• where $V_S$ is the source voltage, $V_R$ is the regulated voltage and $X_L$ is the line reactance.
• For normal operation, magnitudes of $V_S$ and $V_R$ do not vary much.
• Thus, the maximum power handling capability of a transmission line is proportional to the square of its voltage and inversely proportional to the line reactance.
• So, to increase the maximum power transfer capability of a transmission line,  either increase the voltage level or reduce the line reactance value.

Maximum power transfer capability of a transmission line can be increased by either increasing the voltage level or reducing the line reactance value.
