Suppression of harmonics
1) Fundamental frequency current = 1.0 x In. Harmonics current before fault = 0.0 x In, harmonics fault
current 2.0 x Start value. Results based on statistical distribution of 1000 measurement.
2) Includes the delay of the signal output contact
3) Maximum Start value = 2.5 x In, Start value multiples in range of 2 to 20
