IEEE 519 Short-Term and
Long-Term Harmonic
Results
The six data tables that are listed, provide an indication of individual current
harmonic distortion and TDD (Total Demand Distortion). If you have selected
voltage as the output parameter the tables list voltage distortions and THD
(Total Harmonic Distortion).
