VIEWING DATA IN THE DDFR ARCHIVER
CHAPTER 5: RETRIEVING AND VIEWING DDFR ARCHIVER DATA
This screen lists all the Events that were recorded and archived by that DDFR to the
Archiver. The Events are itemized both by the UR relays which recorded them and by the
date and time on which each Event occurred in that relay.
Note
For Datalogger file naming conventions see section 5.1.3.

Click on one of the Data Logger records listed, to open the file in a
COMTRADE viewer.
FIGURE 5–19: Archived Data Logger Waveform COMTRADE File
The Data Logger Records retrieved from the protection relays are stored in the DDFR in
COMTRADE-2002 standard format. All files required to comply to the COMTRADE-2002
format (including .CFG, .HDR, and .DAT) are stored with all appropriate fields populated.
When the protection relay that initially recorded the Data Logger record does not record
these records as COMTRADE in its native format, the record is converted to a COMTRADE
file and stored in the DDFR.
5.3.4.1 Viewing the Retrieved Data Logger Files
The Data Logger files are viewed in the Waveform viewer. For an in-depth explanation of
the tool, please refer to the Waveform Viewer section (section 5.3.3.6).
5.3.4.2 Storage of Data Logger Records
The Data Logger Records are stored in folders on the local drive categorized first by the
DDFR name. A folder is created for each DDFR. Three folders are created within each DDFR
folder to store the Oscillography Records, the Data Logger Records and the backup of the
Event Records.
All folders can be explored by returning to the \Data folder.
