The accuracy of harmonics amplitude expressed in % is evaluated considering the accuracy of the parameters ratio
(*) Voltage harmonics are zeroed in the below conditions:
1st harmonic: if value < 0.5V
DC, 2nd to 25th harmonics: if harmonic value <0.5% of fundamental value or if value < 0.5V
Current harmonics are zeroed in the below conditions:
1st harmonic: if value < 0.5A
DC, 2nd to 25th harmonics: if harmonic value <0.5% of fundamental value or if value < 0.5A
