After modification of any value, the user has to save the changes by clicking on the button Save before changing tabs, otherwise the changes will be lost. There, the user is able to modify any of those values. y selecting one conductor, all its properties are displayed in the form.

All the available conductors are listed in the Conductor Code Word combo box. Edit y Form Conductors are identified by a unique code word. This can be done in two ways: using the form for an individual conductor type, or using the table for all the conductor types available. of 13ģ Conductor Type This section is used to add, remove, rename, and edit the information related to the conductor types. Ampere to MVA Limit Conversion This section converts the limits of the transmission line from Amperes to MVAs, given the voltage base, and vice versa. ote: To see the specific calculations used in this program, see the Calculations section, at the end of this document. The characteristic impedance and propagation factor are displayed in the Lumped values section. The computed geometric mean radius and geometric mean distance are shown in the istributed values section. Intermediate Results The intermediate values calculated to compute the R, X, and G values are displayed here. The Power Surge Impedance Loading is calculated only for the lumped section. The values for R, X, and G are shown in three different sections, each section corresponding to istributed, Lumped or Total, and Per Unit values, respectively. Final Results When all the input data is entered, the results automatically will be displayed. It is also automatically computed as the inverse of the impedance base.
This value is automatically computed when the power base and the voltage base are entered or modified. of 13Ģ Power ase: Voltage ase: Impedance ase: Admittance ase: The system voltampere base in MVA. The final and intermediate results will also be shown in the system specified here. The options are English system or Metric (SI) system. The line length units specify the measurement system to use when entering the line length. The units are miles when using English system, or kilometers when using the Metric (SI) system. This is the value of the distance of the transmission line. To add, remove or edit a specific tower configuration, please go to the Tower Configuration section below. This combo box lists all the tower configurations available in the Tower Configurations table. To add, remove or edit a specific conductor and its characteristics, see Conductor Type section below. Input ata Conductor Type: Tower Configuration: Line Length: Line Length Units: This is the combo box that lists all the conductor types available in the Conductors table. Calculations The following controls are part of the calculations section: Parameters Calculation This section is to enter the necessary data to compute the characteristic line parameters that are shown in the Results panel. These values are computed as distributed (per unit of distance), lumped or total (for a specific line distance), and in per-unit. The parameters computed are the resistance R, reactance X, susceptance, and conductance G.
