Preparing for Analysis

Full Connectivity

Until all items are fully connected, you cannot select an analysis focus. If you try, unconnected items are displayed in red and EasyPower generates an error report.

You can right-click on an item in the report and then open the item's data dialog box or find the item in the one-line. You can also double-click on the item in the report to open the item's data dialog box and edit the item.

Required Database Fields

Certain database information is required before you can run an analysis. For example, if you did not give the impedances of a cable, it is not possible to do a meaningful short circuit analysis. If you try to select an analysis focus without specifying all required database fields, you will get an error report listing the ID name and type of each incomplete item.

You can right-click on an item in the report and then open the item's data dialog box or find the item in the one-line. You can also double-click on the item in the report to open the item's data dialog box and edit the item.

Recalculating Per-unit Data

EasyPower automatically keeps appropriate per-unit equivalencies of your equipment parameters updated. However, if you open a very old database, you might want to force all of the per-unit data to be recalculated. This is done from the Database Edit focus by clicking Tools > Re‑calc Per-Unit. The updated per-unit values will be saved with the database the next time you save the database.

Tip: You can also press F9 to quickly recalculate per-unit data.
