The Power Xpert Software Quality Manager has a Waveform Viewer that can read
COMTRADE files. You can use the Waveform Viewer to examine the waveform data
in detail, as well as the metadata about each waveform. The following figure shows a
COMTRADE file, taken from the meter, displayed in the Waveform Viewer.
ACCESSING THE COMTRADE FILES
COMTRADE file sets can be found in the
waveforms
directory of the meter’s anonymous
FTP site. When copying these files to your local computer, make sure you get all three
files in the set. Each file in a set has the same file name, such as wv00000001. The last
characters of the filename are simply sequential numbers in hexadecimal, used to give
each set unique filenames.
H.3. Energy Logs
Energy log file entries (rows) are captured in increments set for the Profile Interval on
the Load Profile Setup screen. The default interval is 15 minutes. The log file format is a
comma-separated values (CSV) file that can be readily loaded into Microsoft Excel, Micro -
soft Access, or other spreadsheet, graphing, and database applications.
The log files contain the following data fields:
• Date
• Time
• Forward kW Demand
• Reverse kW Demand
• Net kW Demand
