6.4 Data Conversions
6.4.1 Exporting COMTRADE Files
These instructions cover exporting COMTRADE files generated from
waveform data captured by the Model 933A. During the exportation
process, two COMTRADE files, a .dat and a .cfg file, are generated from
waveform file and saved on the host pc.
Running PSCSV 933 Software, the opened waveform data is converted
directly into these two files. The method used to capture waveform data
in these instructions is by setting a voltage trigger to create a waveform
record. The Model 933A automatically creates a waveform record when a
configured 933A trigger becomes active (when the required event occurs).
The specific trigger configured in these instructions initiates recording
when the phase voltage exceeds a limit, and the 933A begins recording
data to flash memory. This waveform record is then downloaded to the
host pc. Once stored on the pc, the record is easily converted into two
COMTRADE files. Without a captured waveform file there will be no
information to convert to COMTRADE.
Basic Steps Required
1. Set up triggers in the 933A (using front panel or PSCSV).*
2. Connect signal wires.*
3. Erase previous logged data.
4. Instigate or wait for an event.
5. Download the event and waveform data (separately).
6. Export COMTRADE Files.
*Note: Order of these steps may be changed according to type of testing
performed. For complete instructions on triggers, see Chapter 7.
Power Sentinel CSV Software version 1.129, dated April 2010, was used in
creating these instructions.
