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 may choose to manually complete the data form, however, it is preferable to provide the parameters of an FD line by loading the pun file in its data form.
