As illustrated in Figure 5-63a, a standard computer is attached to a hub in which an ABB DPU 2000R relay with
Internet Explorer 5.0 installed is operating. The address of the relay is 198.113.65.110
When executing Internet Explorer, initially, three subdirectories are present
OSCILLOGRPH
FAULTREC
OPERREC
Files are contained beneath these directories on the FTP site as illustrated in FIGURE 5-4
FIGURE 5-63b: FTP SCREEN FOR ACCESS OF FAULT, OSCILLOGRAPHIC, AND OPERATION
FILES.
As illustrated in FIGURE 5-63b, the method to access the FTP is listed on the browser screen capture.
If one selects the file folder “OSCGRPH”, several subdirectories may be visible representing
the COMTRADE oscillographic records present in the relay. If several oscillographic files are
present in the DPU 2000R, then several subdirectories are visible. This is illustrated in
FIGURE 5-63c. If there are no oscillographic records present in the relay, then no
subdirectories will be visible .
If one would then select a specific REC X file, then the COMTRADE files for that record are
visible as illustrated in FIGURE 5-63d. These files can be viewed using the ABB utility
WAVEWIN. The filename is composed of the date MM/DD/YY_ Time in MS of the fault.
