Viewer Power Flow Information Visualization
In addition to the standard feeder and phase views, the Viewer provides options for visualizing the power flow information. The Viewer Legend, which is opened from the Help menu, displays legend information based on the view selected in the Viewer's Options menu.

Currents: the current range
Loading: the per unit current range.
Voltage Per Unit: the per unit voltage range.
Note: If a feeder is solved in kVA mode, then the voltage will be constant.
Nominal Voltages: the nominal voltage range.
Note: If an area of the model is set as Power Flow Disabled the voltage configured within database table NETWORK_COMPONENTS will be utilized instead.
Limits: conductor Amp limits.
Flow Direction
The Viewer will render any of the view options with flow direction by selecting Show Flow Direction from the Viewer's
Options menu (Shift-D). The example below shows Feeder with flow direction enabled..
While the power flow is solving, or when a solution has failed, hash marks are displayed instead of arrows. Because this is a power flow solution, looped and parallel areas can still display flow direction arrows. These arrows will point to the equilibrium spot. If power flow is not licensed, the arrows will show a simpler topological flow that cannot detect an equilibrium point.
Line Catalog Information
The Line Catalog Information dialog box displays power flow line catalog information for a conductor selected in the Viewer. To see the Line Catalog Information, select a conductor, launch its Control Tool, and click the Line Catalog Info... button.
The dialog box has two panes containing the following information.
