This procedure shows how to define current settings and requested spare capacity for bus load lines and to perform validations of bus loads.
-
Associate loads with buses individually or in batch mode.
-
Select Actions > Batch Load Association.
-
On the Batch Load Association dialog, under Power distribution board, select a power distribution board.
-
From the Bus list, select a specific bus.
-
Select the Bus tab.
-
Type values in the Line current and Overload percentage boxes.
-
Enter or modify other values as required.
-
On the Loads tab, select Recalculate to ensure that calculations for Total running load and Total peak load are up to date.
-
Close the Batch Load Association dialog.
-
In the Electrical Index, select one or more PDBs or buses.
If Step 8 of this procedure has not been performed on some PDB buses, select Actions > Calculate Bus Loads.
-
Select Actions > Total Bus Load Validation.
The software calculates the load data for the selected buses and displays the results on the Total Bus Load Validation Dialog.
-
If required, select Excel Report to view the results in an Excel file.
-
The software uses the total bus amperes as the basis for calculating the total bus load, including any loads connected downstream. The input for the calculation comes from the consumed active and reactive loads.
-
The software does not perform bus load validation for loads that have incomplete data, that is, where any of the following properties has a value of zero:
-
The consumed active load.
-
The consumed reactive load.
-
The coincidence factor (X, Y, Z, or ZZ) that applies for the load.
-
Operating mode (governs the coincidence factor used in consumed electrical power calculations.
-
Demand factor.
-
Power factor at Demand
-
Efficiency at Demand.
