Power quality measurements
The meter provides complete harmonic distortion metering,
recording and real-time reporting, up to the 63rd harmonic for all
voltage and current inputs.
The following power quality measurements are available:
-
Individual harmonics (odd harmonics up to 63rd)
-
Total harmonic distortion (THD, thd) for current and voltage (line-to-line, line-to neutral)
-
Total demand distortion (TDD)
-
K-factor, Crest factor
-
Neutral current metering and ground current calculation
The following harmonics data is available on the display:
-
Numeric magnitude and angle of the fundamental (first) harmonic.
-
Graphical display of the 3rd to 31st harmonics, expressed as a percentage of the fundamental harmonic.
