Chapter 15 COMTRADE and PQDIF Converters
The COMTRADE and PQDIF file converters allow you to convert waveforms into
COMTRADE or PQDIF file format, and data log tables
– into PQDIF format.
Manual Converting
To manually convert your waveforms or a data log into COMTRADE or PQDIF
format:
1. Click on the Export button on the PAS
toolbar.
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.
