Figure 1: Panel Data Dialog Box
This dialog box includes the following areas and tabs:
Figure 1: Panel Data Dialog Box
| Option | Description |
|---|---|
| ID Name | Uniquely identifies the panel. This ID name can be up to 16 characters long. The names default to PNL-1, PNL-2, PNL-3... as you enter new panels on the one-line, but you can change those names to make them more descriptive if needed. |
| Base kV | The base kV of the panel. |
| Upstream Rating | The minimum amp rating of equipment that is upstream from the panel (such as breakers, transformers, or cables). This information is for reference in certain specific configurations of EasyPower and is not generally visible. |
|
Spreadsheet View and Configure |
See Spreadsheet View for information about these options. |
| Lock Auto-Sizing | When this check box is selected, the panel cannot be auto-sized. |
| Tools | Use to enter tool information about the panel. See Edit Tools for more information. |
Use Spreadsheet View to configure the columns that appear in the spreadsheet. You can create new configurations that display only selected columns. To create a new configuration, click Configure. In the Database Print Config dialog box, type the new configuration name in the Configuration field, and select the desired column headings in the Columns pane.
Use the Select All check box to include all the columns, or Clear All to clear all columns and select only those you want to see.
Use Delete to remove the selected configuration.
Close saves your changes and closes the dialog box.

Figure 4: Incoming Tab in Panel Data
| Option | Description |
|---|---|
| Incoming Device Type |
You can select the type of incoming protective device type for the panel. The choices available are:
|
| Incoming Branch | You can select the incoming branch equipment such as cables, transformers or busways. All the branches connected to the panel in the one-line are displayed in the list. |
| Incoming Device Settings | Opens the data dialog for the main fuse or main breaker that has been specified as the incoming device type. Refer to Low Voltage Breaker Data or Fused Switch Data for details. |
| Device Information | Information on the selected main breaker or main fuse. |
This is a spreadsheet listing similar to the Device Library. When you place a new panel on the one-line, the first time you open its database dialog and click on the Description tab, EasyPower displays the Panel Schedule Spreadsheet Creation Wizard which enables you to select the number of rows you want. Clear the check box at the bottom of the wizard dialog if you don't want it to appear with each new panel.
Figure 5: Panel Schedule Spreadsheet Creation Wizard Dialog Box
When you click on the Description tab, additional buttons become available on the panel dialog box toolbar. Some of these buttons are the same as those in the Device Library (see EasyPower Device Library) and they offer another way to add rows if the wizard is not used.
Figure 6: Description Tab of Panel Data Dialog Box
| Option | Description |
|---|---|
| Library | The list contains all of the same schedules as the Device Library. To enter a listing other than those contained in the list, create a new page in the panel section of the Device Library. |
| Schedule | This list enables you to specify in which Device Library Schedule your chosen Library Load spreadsheet is located. To enter a listing other than those contained in the list, create a new page in the panel section of the Device Library. |
| Panel Load Units | Select the panel load units, from VA or Amps. |
| View | These options enable you to choose which of the panels you want to view: detailed left, right or both. The choice Simplified 3 Phase shows the ABC buses in the middle with the loads on both sides of the spreadsheet. |
| Export | The spreadsheets can be exported to metafiles (.WMF) and delimited database text files (.CSV). Export is beside the Print button on the panel dialog box toolbar when the viewing the Description tab. |
| Option | Description |
|---|---|
| ECR Type | This is a reference for a type of electrical change request. It is only used in very specific configurations of EasyPower and is otherwise unavailable. |
| Preassigned | Indicates if a change request is pending for this item. It is only used in very specific configurations of EasyPower and is otherwise unavailable. |
| Library Load | This list corresponds directly to the Library Load column in the Device Library. After you have made selections in the Library, Schedule and Library Load fields, all of the following data cells are automatically filled in as soon as you click on another cell. You may also double-click on the cell to enter something different than what is listed. |
| Status | The column is a toggle "On/Off" to indicate if this particular item is currently connected to the panel. Turning any load as “off” is similar to deactivating them in the one-line. |
| Load Type |
You can select from three types of load:
|
| Facility | The facility (building) for the panel row. Facilities are set up on the menu beneath Tools > Options. |
| Location | The location within the facility for the panel row. Locations are set up on the menu beneath Tools > Options. |
| Floor | The floor of the facility where the panel row is located. Floors set up on the menu beneath Tools > Options. |
The rest of the fields correspond directly to those in the Device Library. See EasyPower Device Library for more information.
Panels are validated upon creation. That means that if you create a panel and do not input any data, you can still go into an analysis focus without receiving an error message. When you create a row in this spreadsheet the loads are set to zero until you change them. This means the panel (unlike the MCC) remains validated for analysis even after you have created rows but have not input any data.
If you are making a custom entry, you will notice that many of the data cells contain lists of items. Some of the cells have bold headings, and when they are selected the Calculate button becomes active. Clicking it calculates the data for those cells. You can select several cells at a time before clicking the Calculate button. For instance, clicking on the header selects the entire column.
Because the panel is a library, along with the Calculate button, all of the other editing features are identical to those listed in the customizing section for the Device Library. See Customizing the Device Library for more information.
The summary tab sums all the connected loads and displays results for total connected, demand, code factor and design. There are two sections in this summary: Panel Load and Including Downstream Load.
Figure 7: Summary tab of Panel Data Dialog Box
| Option | Description |
|---|---|
| Override with User Values | This check box enables you to enter your own data. You can enter measured data or assumed data in the available fields. If this check box is not enabled then the program calculates all the downstream loads and displays the total. For this feature to work, it is necessary to have a source upstream to the panel. This feature is applicable only to radial distribution systems. Downstream branches with any power source are not accounted for. |
This summarizes the loads fed directly from this panel. It does not include loads fed through downstream sub-panels. These are not user-definable fields. They are updated automatically when you make changes in the spreadsheet of the Description tab. The watts and vars shown in this table do not reflect the downstream load of the sub-panels.

Figure 8: Power Flow Tab of Panel Data Dialog Box
SCADA data is derived from real time, or metered data, and converted to an ASCII format which can be read into EasyPower. SCADA data is read in as a 100% scaling factor load. The load value is multiplied by the user-defined scaling factor. This provides a way to adjust SCADA loads to form new cases.
Use the Harmonics tab to indicate whether this equipment item is introducing harmonics into your power system.
Figure 9: Harmonics Tab
| Option | Description | |||||||||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Load Type |
The default is Linear, indicating the equipment does not produce harmonics. Choosing Harmonic makes the item an harmonic source and makes other fields in this tab available to edit. Note:
|
|||||||||||||||||||||
| Fundamental Amps |
Use to set the fundamental amps. The options are as follows:
To use fundamental current calculated by power flow, select Calculated from Power Flow in the Summation Fundamental Voltage area of the Harmonics Options > Control dialog box. |
|||||||||||||||||||||
| Harmonic Spreadsheet |
Use the spreadsheet to enter the harmonic spectrum produced by this item. You can enter up to 30 different harmonics in each equipment item. In the spreadsheet, enter the Harmonic Number (such as 5 for the 5th harmonic), the Harmonic Current in percent of the Fundamental Amps, and the Current Angle. By indicating the current angle, you can simulate transformer phase shift effects on rectifiers so appropriate canceling can take place. The harmonic may be integer or non-integer. |
|||||||||||||||||||||
| Library Load |
Common harmonic spectra may be entered from the device library. For instructions on how to enter your own spectra information, see Harmonics with Spectrum™. After selecting a particular device library spectrum from the Mfr and Type lists, click Import, and that spectrum is entered into the harmonic spreadsheet. |
|||||||||||||||||||||
| Resistance Factor |
EasyPower offers two methods for calculating RH:
RH = RFund * H R-EXP RH = RFund * (1+ECF*H2)/(1+ECF) EasyPower defaults all skin effect correction to R-EXP and a value of 0.5.
|
The arc flash hazard tab is similar to that of an MCC. See Arc Flash Hazard for details. Since the panel can be faulted like a bus, you can perform arc flash hazard analysis directly.
Note: This information is used in certain specific configurations of EasyPower and is not generally visible.
