Linking to Waveforms
When displaying the PQ report, Power Software establishes links between the
events and waveform log records related to the events. PQ events, for which Power
Software finds related links, are displayed in blue. To check a list of the event links,
click on the colored event ID with the left mouse button. To directly move to the
related waveform record, click on the corresponding list item.
Retrieving Waveforms Online
If you programmed the PQ recorder to record waveforms on power quality events,
you can upload the waveforms related to a specific event online if they have not yet
been retrieved and stored to the database on your PC. Events for which Power
Software did not find a corresponding waveform in the database are colored black.
Click on the event ID, click on the “Retrieve Waveform” prompt, and then point to a
database to which you want the waveform to be stored.
Viewing the ITI (CBEMA) Curve
Transient overvoltages (impulsive transients) and short-duration voltage variations (dips
and temporary overvoltages) can be viewed as magnitude/duration pairs on the ITIC (the
Information Technology Industry Council, formerly CBEMA) curve chart. To view an ITI
curve chart, click on the “ITI” button on the window toolbar.
