Commands within the Line Database allow you to compute the line’s electrical parameters and display them in the TTY Form.
A sample report showing the overall electrical parameters of the above line is shown below. The report shows the overall sequence impedance, susceptance and charging MVA of the line. It also shows the zero sequence mutual-coupling impedance for each pair of parallel lines.
It is also possible to output the impedance, admittance, susceptance and capacitance matrices in the phase domain.
