1) Set Operate delay time = 0,02 s, Operate curve type = ANSI defi nite time, Measurement mode = default (depends on stage), current before
fault = 0.0 x In, fn = 50 Hz, fault current in one phase with nominal frequency injected from random phase angle, results based on statistical
distribution of 1000 measurements
