Figure 6-20. Fault Record Filenames
Only one oscillographic report file can be requested at a time. Reports are transmitted in COMTRADE
format. A configuration file (CFG), a data file (DAT), or a header report (HDR) can be requested. Header
files contain the fault summary report followed by all the pertinent settings that are associated with the
requested fault record. These settings include the following:
• BESTlogic settings for User Programmable Logic Scheme.
• User Programmable Label settings, Global I/O settings.
• The protection setting group active during the fault.
• General protection settings.
• Fault reporting settings.
• Breaker monitoring settings.
• Alarm settings.
Files can be requested in ASCII or binary format but both file transfers use the same format. Binary file
transfer is much faster and consumes less disk space. ASCII format data is human readable and can be
analyzed by standard text editing software. Software for IBM compatible computers is available from
Basler Electric to convert binary files to ASCII format. The download protocol may be either XMODEM or
XMODEM CRC format. For ease of reference, the name of the downloaded file should be the same as
the command.
SEQUENCE OF EVENTS RECORDER
A sequence of events recorder (SER) report is very useful in reconstructing the exact sequence and
timing of events during a power disturbance or even normal system operations. The SER tracks over 100
data points by monitoring the internal and external status of the relay. Data points are scanned every
quarter-cycle. All changes of state that occur during each scan are time tagged to 1 millisecond
resolution. A total of 255 changes are stored in volatile memory; when the SER memory becomes full, the
oldest record is replaced by the latest one acquired.
The SER monitors the following points and conditions:
• Single-state events such as resetting demands or targets, changing settings, etc.
• Programmable logic variables
• Targets
• Relay trouble alarm variables
• Programmable alarm variables
• Output contact status
• Fault reporting trigger expressions
