3. Check the Enabled box to visualize harmonic faults on
the spectrum graph and in harmonic tables.
Harmonics that exceed selected compliance levels are colored
in red on the graph and in the tables.
Viewing a Spectrum Table
Click on the button on the local toolbar to display the
harmonics spectrum in a tabular view for a selected phase or
for all phases together.
The spectrum table shows voltage, current, active power and
reactive power harmonic components both in percent of the
fundamental and in natural units, and harmonic phase
angles.
To change a phase, click on the window with the right mouse
button, select “Options...”, check the phase you want
Waveform Viewing Options
See Working with Graphic Windows for more information on
working with waveforms.
Viewing Phasor Diagrams
The phasor diagrams show you relative magnitudes and
angles of the three-phase voltage and current fundamental
component. All angles are shown relative to the reference
voltage channel.
To change the reference channel, click on the waveform
window with the right mouse button, select “Options...”, click
on the “Phasor” tab, check the channel you want to make a
reference channel, and then click “OK”.
