A 20 kV transmission line has a series impedance of (4 + j60) Ω ...
The series impedance of the transmission line is given as (4 + j60) ohms.
The real part of the impedance, 4 ohms, represents the resistance of the transmission line. This resistance is due to the losses in the line, such as conductor resistance and losses in insulating materials.
The imaginary part of the impedance, j60 ohms, represents the reactance of the transmission line. This reactance is due to the inductive or capacitive components of the line. In this case, the positive imaginary part indicates that the transmission line has inductive reactance.
The impedance of the transmission line affects the flow of current and voltage along the line. The resistance component causes a voltage drop, while the reactance component causes a phase shift between the current and voltage.
