How to get transmission line parameters using Tower Type from DIgSILENT PowerFactory

1. Create a new project called Exp3, use 60 Hz for frequency 2. Open the data manager and select the Active Project

3. Push on the New Object icon 3.1. In Elements, select Types for Net Elements, and in Element, choose Tower Type (TypTow), then

OK.

3.2. The following window will be displayed where we will input all the required data.

4. Let’s start by filling out Name, Nominal Frequency, Number of Earth Wires, Number of Line Circuits,

Transposition, Input Mode, and Earth Conductivity as follows:

5. Now, let’s continue with Conductor Types of Line Circuits

5.1. Right click on Conductor Types TypCond of Circuit 1 and choose Select Element/Type…

5.2. The following screen will be displayed where one can create a new conductor type.

5.3. To do so, click on New Object where one can input the conductor data for each phase

5.4. Fill out the conductor type as follows:

6. Now, let’s input data for Types of Earth Conductors (shield conductors). To do so, follow similar

steps from5.1 to 5.4 filling out the appropriate data for Earth Conductor 1

8. The General Tab should look like this

9. Continue with the Geometry Tab, where one can input the location (geometry) of the line and earth

conductors, the x- and y-axis are located at earth level and at the center of the tower, respectively.

12. Finally, push Calculate button. The results will be displayed on the Output Window.

13. Copy the results to the clip board. To do so, right click and choose copy where the following window

will be displayed:
