Mask and Parameters
The calculation of the electrical parameters of a line from its geometrical parameters can be done with the Line Data auxiliary module. The resulting EMTP output file (*.pun) contains the electrical line parameters required by HYPERSIM. The user can manually fill in the data form. However, preferably the user provides the parameters of an FD line by loading the pun file in the data form.
