Switched Shunt Information (Run Mode)
The Switched Shunt Information dialog can be displayed by placing the cursor on a switched shunt
display object and right-clicking or right-clicking on a switched shunt record in the Switched Shunt
Display and choosing Show Dialog. This is very similar to its Edit mode counterpart. The dialog has
the following fields:
Bus Number
Unique number between 1 and 2,147,483,647 (equals 2^31 minus 1) used to identify the bus to
which the switched shunt is attached. This drop down list identifies the buses in the case with
switched shunts that also have valid display filters. Use the spin button to step through the list of
shunts in the case. Multiple switched shunts are allowed at a bus but only one is allowed to be on
automatic control.
Find By Number
To find a switched shunt by its bus number, enter the number into the Bus Number field. Then click
the Find By Number button.
Bus Name
Unique alphabetic identifier for the bus to which the switched shunt is attached, consisting of up to
eight characters. This dropdown box lists the names of all the switched shunt buses in the case with
valid display filters.
Find By Name
To find a switched shunt by its name, enter the bus name into the Bus Name field (case insensitive).
Then click the Find By Name button.
Shunt ID
Since multiple switched shunts are allowed on a single bus, each shunt is identified by a unique
Shunt ID.
Find…
If you do not know the exact switched shunt bus number or name you are looking for, you can click
this button to open the advanced search engine.
Status
Status of the switched shunt, either Closed (connected to terminal bus) or Open (not connected). On
the oneline, the switched shunt can be opened by placing the cursor on the (red) circuit breaker box
and clicking, and it can be closed by placing the cursor on the (green) box and again clicking. You
can also use this status field to change the switched shunt's status. Note that the switched shunt is
only available for automatic control when its status is closed.
Energized
Indicates if the switched shunt is energized. This is not the same as the Open or Closed status. A
switched shunt may be in-service itself (closed) but not be energized, based on the statuses of other
devices around the switched shunt. For example, in a full topology model, it is not uncommon for a
switched shunt to have a status of Closed, but the switched shunt is not energized if a branch of
type Circuit Breaker connecting the switched shunt to the system has a status of Open.
Labels
Clicking on this button will open the Label Manager Dialog listing all the labels assigned for the
selected switched shunt.
