Consider a lossy transmission line with $V_1$ and $V_2$ as the sending and receiving end voltages, respectively. $Z$ and $X$ are the series impedance and reactance of the line, respectively. The steady-state stability limit for the transmission line will be
- greater than $ \begin{vmatrix} \frac{V_1V_2}{X} \end{vmatrix} \\ $
- less than $ \begin{vmatrix} \frac{V_1V_2}{X} \end{vmatrix} \\ $
- equal to $ \begin{vmatrix} \frac{V_1V_2}{X} \end{vmatrix} \\ $
- equal to $ \begin{vmatrix} \frac{V_1V_2}{Z} \end{vmatrix} \\ $
