Option Description
Fault Type Four different types of faults are available during a short circuit analysis. The default is 3 Phase which is generally used to determine the highest available currents for equipment duty comparisons, and relaying. The other types, Line to Ground, Double Line to Ground, and Line to Line are generally used for specialized relaying applications or system troubleshooting.
"Fault All" Filters Enables you to specify a specific bus Area, Zone, and kV Range that to fault and report when you fault multiple or all buses.
Equipment Duty Threshold

Sets the lower limit for flagging breaker violations in SmartDuty™. If the threshold is set to -10 percent, SmartDuty™ flags all equipment which has short circuit duties within 10 percent of their maximum rating (greater than 90% of their rating).

Note: The ability to automatically check equipment duties during analysis is only available if you have purchased the SmartDuty™ option to EasyPower.

Note: You must click Equipment Duty from the Short Circuit focus for this field to have any effect on the one-line result output. 
For this field to have any effect for text result output, you must select the Equipment Duty check box in the Text Output tab of the Short Circuit Options dialog box.
