Accuracy of harmonic amplitudes expressed in % is evaluated considering the accuracy of parameters’ ratio
(*) Harmonic voltages will be zeroed under the following conditions:
1st harmonic: value <0.5V
DC, 2nd to 25th harmonic: harmonic value <0.5% fundamental value or value <0.5V
(*) Harmonic currents will be zeroed under the following conditions
1st harmonic: value <1%FS[A]
DC, 2nd to 25th harmonic: harmonic value <0.5% fundamental value or value <1%FS[A].
