Influence of Power Line Parameters on Their Properties

Power line, where more than two distributed parameters (resistance and reactance) are taken into account, is considered as two-port network. Formulas, giving an unambiguous relationship between electrical quantities at the ports of a two-port network, do not detailed show the influence of three or four parameters (in addition, conductance and capacitive susceptance) on line electrical quantities. The influence of distributed parameters occurs through the sine and hyperbolic sine of the components of propagation factor. How distributed parameters should be changed it depends on what properties of the line it is desirable to get. More adverse of distributed parameters is specific susceptance both in single and parallel lines.
