Power quality analysis values
The power quality analysis values use the following abbreviations:
-
HC (Harmonic Content) =
-
H1 = Fundamental Content
-
THD (Total Harmonic Distortion) = HC/H1 X 100%
THD provides a measure of the total distortion present in a waveform. THD is the ratio of harmonic content to the fundamental and provides a general indication of the quality of a waveform. THD is calculated for both voltage and current.
The following table lists the power quality values of the meter:
