4.3.1.1 WAVEFORM ANALYSIS
(OPTION- Harmonic Analysis and Synthesis)
Waveform analysis functions are optionally available to report both magnitude and phase angle (relative to
0° of the fundamental voltage waveform) of each harmonic for metered voltage and current waveforms.
THD, ODD and EVEN harmonic distortion measurement data can also be displayed
The harmonic content is displayed from the 2nd up to the 51st harmonic, depending on the number of
samples analyzed. See the
EDIT
key function described below.
Pressing the
DISPLAY
key repeatedly will display the following screen.
HARMONIC ANALYSIS:
“ENTER” UPDATE & DISPLAY HARMONIC DATA
“EDIT” HARMONIC ANALYSIS SETUP SCREEN
“HELP” HARMONIC ANALYSIS HOTKEY LIST
Pressing the
DISPLAY
key repeatedly at this point will display the HARMONIC DATA in memory with
screens similar to the following.
Ф
A VOLTAGE THD=0.1 % OHD=0% EHD=0.1%
HARMONIC: 2nd 3rd 4th 5th 6th
CONTENT: .1% 0% 0% 0% 0%
Ф
ANGLE: 0° 0° 0° 0° 0°
THD
is TOTAL HARMONIC DISTORTION for all harmonics of the selected parameter and phase.
OHD
is ODD HARMONIC DISTORTION for all harmonics of the selected parameter and phase.
EHD
is EVEN HARMONIC DISTORTION for all harmonics of the selected parameter and phase.
CONTENT
is displayed as a percentage of the amplitude of the fundamental
Ф
ANGLE
is displayed in the range of -180° to +180°.
