Harmonics

Select Logger > Display Real-Time Values > Harmonics to see the actual harmonic content in the
current, voltage, and power waveforms. A typical display is shown here:
The buttons along the lower left side of the window
select the Channel to be displayed. Only one
channel may be viewed at a time. The voltage and
current harmonics are presented graphically in the
upper part of the window. The ordinate (y-axis) is
scaled in percent of the fundamental. The abscissa
(x-axis) is the harmonic. Both even and odd
harmonics plus DC are shown.
The actual value of the voltage and current for each harmonic may be found in the Harmonic Values
box. By clicking on the arrow buttons, higher and lower order harmonics may be selected. Though
only the first 31 harmonics are displayed in the graph, the Harmonic Values function can be used to
view the values up to the 63 harmonic. The Waveform Values box provides summary statistics for
the overall current and voltage waveforms. This includes the RMS value, Total Harmonic Distortion
(THD), Peak values, Crest Factor, and K-Factor.

of the total RMS value (CSA and IEC
standard).
