This module allows the user to calculate arc flash incident energy, flash boundary, both arc and fault currents, safe working distance. EA-PSM calculations are validated in accordance with IEEE 1584 standard. It is possible to choose from different equipment types and calculate incident energy at any selected distance. Arc flash calculation results of EA-PSM can be used to optimize protection devices and improve laborers working conditions by minimizing arc flash hazard-exposed energy and estimating safe working distance.
To calculate arc flash user first has to select calculation parameters. This can be done by opening fault bus properties and switching to “Substation” panel ( Figure 8.10 ). Arc flash calculation requires installation type to be selected. EA-PSM offers 4 installation/equipment types that comply with IEEE 1584 standard:
Open air
Switchgear
MCC and panels (when voltage below 15kV)
Cables
The user has an option to manually determine the arc flash distance. It will be used for calculating the incident energy.
After all parameters are set click “Apply” and “Ok” buttons save and close the dialog. Now arc flash can be calculated by pressing “Calculate” at the top bar and selecting “Calculate arc flash” (Shortcut to this action is F8). Results table will pop up, the data of which can be exported to the Excel sheet as with other result tables.
It is also possible to export a pdf of a warning label for arc flash. This may be done once the arc flash calculations have been made. The arc flash summary window will have a “Warning label” column in which warning labels for every bus are calculated. If the button is clicked, user will be prompted with the following window:
The user may customize units, displayed date. Clicking button “Save” will allow the user to export the label as .pdf (portable document format) file.
