2. Select the database and a waveform or data log table
you want to export, and then click Open.
3. Select a directory where you want to store your
exported files, type a file name that identifies your
files, select a desired file output format, and then click
on the Save button. The PQDIF files are commonly
recorded in compressed format. If you do not want
your files to be compressed, uncheck the Compress
box before saving the file.
In COMTRADE format, each waveform event is recorded into
a separate file. A COMTRADE waveform file name contains a
site name followed by an ID of the fault or power quality
event, which triggered the waveform record.
PQDIF file names contain a site name followed by a
timestamp of the first event recorded to the file, and may
look like 12KVSUB_20040928T133038.pqd.
Automatic Converting
PAS allows you to automatically convert waveform and data
logs into COMTRADE or PQDIF format at the time you upload
data from your devices via the Upload Scheduler.
