Harmonic List
Harmonic text
display
To view the harmonics magnitude text display, press List from the Harmonic graph
screen on page 3-11. The harmonic parameters displayed on list include: (from leftmost
column) the harmonic/interharmonic frequency in Hz, frequency in number, voltage
rms or maximum load of current (depending on parameter selected), percent amplitude
of harmonics, and harmonic phase angle value.
By default, harmonic and interharmonic frequency values are arranged per increment
of 5Hz. Use the Sort button to organize harmonic text display according to percent
magnitude of the first 60 harmonics relative to the fundamental, followed by the
interharmonic values.
Harmonic phase degree values from 1 to 60 are displayed for voltage and current; while
phase degree values from 1 to 50 are displayed for harmonic watts. Harmonic phase
angle values can be normalized to the phase of the fundamental of the displayed
channel. Use the Norm button to show the normalized phase angle values.
