Faulting a Bus
There are three ways to fault a bus. The easiest way is to double-click on the desired bus. A fault will be placed on the bus using the options selected on the Short Circuit tab and in the Short Circuit Options dialog box.

The results are immediately displayed on the one-line. In this example, the faulted bus current is 16.952 kA, which is shown diagonally on the right side of the bus. The contribution from the upstream branch is 14.616 kA, and the motor contribution is 1.201 kA.
To see text results, select the appropriate report and format in Short Circuit Options on the Text Output tab.
Another way to initiate a fault is to first select a bus (the bus will highlight) and then click 
Fault Bus(es). You can select more than one bus to fault if desired.
To perform a batch fault of all the buses, click Fault Bus(es) without selecting any buses.
You can designate which phases to fault for each fault type in the Short Circuit Options on the Control tab. If the phases you have designated do not match the phases currently selected to appear on the one-line, the program displays a warning and asks if you want to display the appropriate phases for the type of fault you are performing. See Control Tab (IEC) for more information.
