spectrum to let you view a shape of the voltage and current waveforms in
your network.
Viewing a Spectrum Chart
Click on the button to view a spectrum chart for the selected channel.
To change a channel, click on the window with the right mouse button,
select Channels..., check the channel you want displayed, and then click
OK. PAS provides voltage, current, active power and reactive power
spectrum charts.
PAS can give you indication on whether harmonic levels in the sampled
waveforms exceed compliance limits defined by the power quality
standards or local regulations.
To review or change harmonic limits:
1. Click on the spectrum window with the
right mouse button and select
Limits….
2. Select a known harmonics standard, or select Custom and
specify your own harmonic limits.
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.
