Q. Consider a lossless transmission line with only a series reactance X.
(a) Find an expression for the real power transfer capacity of the transmission system.
(b) What is Pmax (the theoretical steady-state limit of a lossless line), which is the maximum power that the line can deliver?
(c) How could the same expressions be used for a three-phase transmission line?
