The Impedance Line Section Data Form lets you specify a line section using available impedance data. An impedance line section is generally used as a place holder that lets you complete the data record for a transmission line when no detailed line construction data are available.
You can open this form in several ways:
-
Pressing the Open Line Section Data Form button 
in the line-section diagram in the Line
Data Form
- Double-clicking on a line-section object in the line-section diagram in the Line Data Form
- Double-clicking on an impedance-section object in the top layout view in the Corridor Data Form.
