The following explanation refers to the examples Configuration F in the Bus Load Configuration Examples.
The images below display a typical situation in which two buses that have the same voltage are tied by coupler and riser circuits.
In the Electrical Engineer:
In a single line diagram:
Smart Electrical makes it possible to calculate the total of bus loads for coupled buses in one of three ways depending on your report preference setting:
Do not include coupled buses
Includes in the calculation only those loads that are connected to the current bus and does not include the loads that are connected on the redundant buses. See Coupled buses calculated independently.
Include coupled buses connected by couplers only
Includes in the calculation the loads connected on the current bus as well as loads connected on all the redundant buses that are connected to the current bus by a coupler circuit. See the .Coupled buses with the "Include coupled buses connected by couplers only" option.
Include coupled buses connected by couplers and risers
Includes in the calculation the loads of the current bus as well as the loads on all the redundant buses that are connected to the current bus by coupler and riser circuits. See the Coupled buses with the "Include buses connected by couplers and risers" option.
