Characteristic
Operate time accuracy in definite time mode
Operate time accuracy in inverse time mode
Suppression of harmonics
Measurement mode = default (depends on stage), current before fault = 0.0 × I
1)
current with nominal frequency injected from random phase angle, results based on statistical
distribution of 1000 measurements
2) Includes the delay of the signal output contact
Start value = 2.5 × I
