Harmonic Analysis Summary

  • The PowerLogic ADVC Controller calculates 2nd to 16th harmonics and Total Harmonic Distortion over 80 ms periods for:

  • 4 currents (three phase currents + earth/ground)

  • 6 phase to phase voltages

  • 6 phase to earth voltages

  • Each value is averaged over a moving 2 s window updated every 500 ms.

  • The magnitude of each harmonic is represented as a percentage of the RMS value of the fundamental, not the total RMS of the distorted waveform.

Total Harmonic Distortion (THD) equals the RMS value of all harmonics divided by the RMS value of the fundamental expressed as a percentage.
