The “Line Data Report” window display a report of the transmission line models.
Functions with right mouse button in line data window:
| Print the Geometrical / Electrical parameters | Print the Geometrical and Electrical parameters in the Line Data Report. |
| Save the Line Data Report in a file | Save the Line Data Report in a text file. |
| Clear the Line Data Report | Clear the current data in the Line Data Report. |
HYPERSIM LINE
The “Hypersim Line” window also allows you to download parameters into Hypersim Line models.
Apply the parameters to the Hypersim Line models that you have selected.
Example of a 735-kV three-phase line transposed.
Check the figure 7.1 for the geometrical parameters of the line and 7.3 for the layout of conductor.
