The Equipment Duty Scenario Comparison Report contains the equipment and scenarios based on your selections in the one-line and in the Scenario Comparison Report Options (see Scenario Comparison Report Options). The information on the report is grouped by bus name and then by equipment name.
You can print the report, export it to Excel, or export it to a CSV file from this spreadsheet view.
Normal configurations may have tie breakers open and buses fed from single feeds. During transition to a different switching configuration, such as during maintenance or an emergency/alternate supply, there may be brief moment that a bus may be fed from multiple sources. If a fault occurs in that state, the fault currents can be higher than in normal configurations. Power flow and arc flash will not require this transient configuration to be modeled as a scenario. However it is important to evaluate this condition for short circuit duty as the equipment is required to withstand or interrupt the fault currents. The Equipment Duty Scenario Comparison report allows you to compare different configurations and identify the worst-case duty.
For each scenario, the program determines either:
The best case scenario is the one with the lowest calculated percentage.
The worst case scenario is the one with the highest calculated percentage.
The Equipment Duty Scenario Comparison Report can show either the best-case or the worst-case scenario for the selected equipment. This is determined by the view you select when you run the report.
You can then modify the views further by selecting the various View buttons in the ribbon.

There are two pairs of view options that work together to control the information that appears in the report: Scenarios and Devices.
The All Scenarios and Worst/Best Scenario buttons are used in conjunction with the All Devices or Overdutied Devices to filter the results. Examples of the report with various combinations selected are shown below.
This report shows all scenarios with the best case identified:

The Equipment Duty Scenario Comparison Report includes slightly different information depending on whether your short circuit calculation method in system options is set to ANSI or IEC. See Short Circuit Options for more information about setting the calculation method.
The ANSI version of the report displays a Vpu column (voltage per-unit). Momentary cycles are reflected in the 1/2 cycle columns. For high-voltage breakers, interrupting cycles are displayed in the Int (interrupting) columns. Interrupting cycles are measured as a number of cycles.

The IEC version of the report displays a C Factor column (voltage correction factor). Momentary cycles are reflected in the Initial columns. For high-voltage breakers, interrupting cycles are displayed in the Breaking columns. Breaking times are measured in seconds.

See System Options for more information.
The Find feature locates specific text within the spreadsheet. As you begin typing, the program searches the spreadsheet for text that matches the text you enter. The search is not case-sensitive, but the character order must match. For example, searching ATS and ats displays the same results, but ATS 4 and ATS 04 displays different results.
The text is highlighted in the spreadsheet, and the number of occurrences where the text appears in the spreadsheet is displayed to the right of the Find box.

You can copy information to the clipboard and then paste it into another document, such as Microsoft Word® or Excel®.
First, select the cells you want to copy, and then click 
Copy (toolbar menu: Edit > Copy).
To remove any result columns from the spreadsheet, right-click on the column header and select Hide Column.
Note: To show columns you have hidden on the spreadsheet, run the report again.
You can export the scenario comparison report to Excel® by clicking Excel in the Export group (toolbar menu: File > Open with EXCEL).
Figure 9: Export to Excel® Button
This opens the report information in a Microsoft Excel file. You can view, edit, and modify the data there.
Note: Any changes you make to the report information in Excel are not written back to EasyPower.
You can export the scenario comparison report to a CSV (comma separated value) file by clicking CSV in the Export group (toolbar menu: File > Export to CSV).
Figure 10: Export to CSV
This opens a dialog box where you can save the report information in a CSV file. You can then view, edit, and modify the data there.
Note: Any changes you make to the report information in the CSV file are not written back to EasyPower.
