Reporting
Event Reports, Event Summaries, and Event Histories
Event Summary
You can retrieve a summary version of stored event reports as event summaries.
These short-form reports present vital information about a triggered event. The
relay generates an event in response to power system faults and other trigger
events (see Triggering Data Captures and Event Reports on page 9.6). The sum-
mary information available depends on the specific relay. See Section 7: Meter-
ing, Monitoring, and Reports in the product-specific instruction manual for the
details of the summary event report for a specific relay.
The relay can be configured to automatically send an event summary on serial
ports (see Automatic Messages on page 15.27).
Viewing the Event Summary
Access the event summary from the communications ports and communications
cards. View and download event summaries from Access Level 1 and higher. You
can independently acknowledge a summary (with the SUM ACK command) at
each communications port so that you and users at other ports (SCADA, Engi-
neering, etc.) can retrieve a complete set of summary reports. To acknowledge
and remove a summary, you must first use the SUM N(EXT) command to view
that summary.
You can use the SUM command to retrieve event summaries by date or date
range, and by event number. (The relay labels each new event with a unique num-
ber as reported in the HIS command history report; see Event History on
page 9.27.)
Table 9.2 lists the SUM commands. See SUMMARY on page 14.52 for complete
information on the SUM command.
You can also view event summaries using the Analytic Assistant tool built into
QuickSet, or with
SYNCHROWAVE Event.
CSUMMARY
The relay outputs a Compressed ASCII summary report for SCADA and other
automation applications. Issue ASCII command CSU to view the Compressed
ASCII summary report. This is a comma-delimited ASCII file. The relay appends
a four-digit hex checksum at the end of the lines in the Compressed ASCII report.
Items included in the Compressed ASCII summary report are similar to those
included in the summary report, although the relay reports the items in a special
order. For the purpose of improving products and services, SEL sometimes
changes the items and item order.
