The Change | Line to Series Capacitor/Reactor command in the Main Window lets you change a transmission line to a series capacitor or series reactor. You must select a line before executing this command.
TO CHANGE A LINE TO A SERIES CAPACITOR:
1. Select a line by clicking the left mouse button once on its symbol.
The line symbol will turn dotted red when selected.
2. Select the Network | Change | Line to Series Capacitor/Reactor command.
Note: This menu item is enabled only if all the following conditions are met: (1) the line’s resistances R and R0 are zero, (2) the line’s positive- and zero-sequence reactances are the same (X=Xo), and (3) the line’s shunt admittances (B,Bo,G,Go) are all zero, and (4) the line is not mutually coupled to other lines.
The Series Capacitor/Reactor dialog box will appear. The program automatically copies the name, circuit ID and the reactance of the line to this new series-capacitor/reactor object. The protective-level current is initially zero.
3. For MOV-protected capacitor only: Enter the protective-level current in amperes.
See Section 4.3 LINES & SERIES CAPACITORS/REACTORS for more information on series-capacitor modeling.
4. Press OK to close the dialog box.
The line symbol will be replaced by a series capacitor or reactor symbol on the one-line diagram.
