Changing the ANSI Standard Time Interval

ANSI standards list three distinct time intervals for short circuits. These are momentary (1/2 cycle), interrupting (5 cycles) and 30 cycle. EasyPower lets you display each of these by selecting the  buttons. You can quickly view all three intervals in succession for a particular fault by clicking one button after another.

You can also view the short circuit results of all of the three time intervals by selecting the three buttons.

Interval values are shown next to a faulted bus.
