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.
