Calculate Downstream Load
|
Calculates the total load on the panel, taking into account the connected load, demand factors, and NEC code factors. |
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. |
Panel Load
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.

Power Flow Tab
Figure 6: Power Flow Tab of Panel Data Dialog Box
SCADA Model
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.
Harmonics Tab
Use the Harmonics tab to indicate whether this equipment item is introducing harmonics into your power system.
Figure 7: 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: For an adjustable frequency drive (AFD), the Load Type is always Harmonic. |
|||||||||||||||||||||
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.
|
Arc Flash Hazard Tab
EasyPower calculates arc flash risk assessment results using the options set on the Arc Flash Hazard tab. The results are calculated for automatic transfer switches, buses, tool points of connection, MCCs, and panels.

AF For This Bus |
You can specify how you would like arc flash results determined for this bus using AF for this Bus. Calculated: When the bus is faulted, EasyPower the performs arc flash hazard analysis using the calculation method specified in Short Circuit Options. EasyPower uses other settings on this tab as part of the calculations. Excluded: Select to exclude the bus from arc flash reports. An example of when you might select this option is for a bus that is required to model the electrical parameters of the system but does not actually represent a piece of electrical equipment. Other applications include nodes and tap-offs (junctions), where energized work is not required. Forced To: When you select this option, you can enter the incident energy and arc flash boundary for this bus. The incident energy and arc flash boundary values are shown on the one-line and in reports and work permits. This can be used for instances where you need to apply a calculation that is outside the scope of the industry standard calculations. |
