If you leave the Triangle box checked, Power Software
connects the ends of the voltage and current vectors showing
you three-phase voltage and current triangles. This is useful
when analyzing voltage and current unbalances.
Phasor diagrams are calculated over one waveform cycle
pointed to by the left marker line. As you move the marker,
the phasor diagrams are updated reflecting the new marker
position.
Viewing Symmetrical Components
Waveform views have an additional pane at the right where
Power Software displays the symmetrical components for
voltages and currents, calculated for the point indicated by
the left marker line.
To enable or disable the symmetrical components, click on
the waveform window with the right mouse button, select
“Options...”, check or uncheck the “Symmetrical components”
box on the “Channels” tab, and then click OK.
Viewing Synchronized Waveforms
If you have a number of devices with synchronized clocks,
you can view waveforms recorded at different locations in
one window. Power Software can synchronize the time axes
for different waveforms so they could be displayed in a single
plot.
To get synchronized waveforms:
1. Put the databases with waveforms into the same
folder, or put the sites from which you uploaded data
to the same group in the sites tree.
