Circuits

The circuit component, used to identify the start of a separate circuit run, must be initial component connected to every substation.  Once connected, other components can then be incrementally added to the circuit/station.  

 

See General Dialog Details for information on commonly used dialog fields and commands, as only the highlighted fields and commands unique to the Circuits dialog are addressed in this topic.
 

 

Circuit Settings:

 

Voltage Dependency Factor - specifies the percentage change in load current per percent change in voltage magnitude.  As  Voltage Dependency Factors may be specified either for an entire circuit or for individual line/cable loads, the circuit specification is applied only to line/cable loads that do not have individual specifications.  For more information, see the Introduction to Power Flow.

 

[Percentage Load Growth] -  opens the Percentage Load Growth dialog shown below, allowing user to specify individual growth factors for each customer class.  The growth factors define annual growth rates for each load type in the circuit, which get incorporated into forecast data and load estimation applications.
