For a short transmission line of impedance ( R + j X ) ( R + j

Question:

For a short transmission line of impedance (R+jX) ohms per phase, show that the maximum power that can be transmitted over the line is

Pmax=VR2Z2(ZVSVRR) where Z=R2+X2

when the sending-end and receiving-end voltages are fixed, and for the condition

\[
\mathrm{Q}=\frac{-\mathrm{V}_{\mathrm{R}}^{2} X}{\mathrm{R}^{2}+X^{2}} \quad \text { when } d \mathrm{P} / d \mathrm{Q}=0
\]
