Duration of short-circuit

Calculations according to IEC are made for 0.1, 0.2, 0.3, 0.5, 1, 2, 3 and 5 s. In addition, calculations are made for a short-circuit duration of 10 ms. In the preferences, an optional custom short-circuit duration in the range between 0.01 and 5 s can be defined.

Calculations according to ICEA are made for 1, 2, 4, 8, 16, 30, 60 and 100 cycles.
