9.5.4
Filtered & Unfiltered Event
Reports
The SIMPRO-100 Relay samples the basic
power system measurands (ac current and ac
voltage) 16 times per power system cycle. The
relay filters the measurands to remove transient
signals. Four times per cycle the relay operates
on the filtered values and reports them in the
event report.
To view the raw inputs to the relay, use the
unfiltered event report retrieved using the serial
port command EVENT n R. Use the unfiltered
event reports to observe:
•
Power system harmonics on current and
voltage channels
•
Decaying dc offset during fault conditions on
IA, IB, or IC
Raw event reports display one extra cycle of data
at the beginning of the report.
9.5.5
Resetting the Event Report
Buffer
The HISTORY R command clears the event
summaries and corresponding event reports from
nonvolatile memory. See Section 6.8.7, page 91
for more information on the HISTORY command.

Sequential Events
Recorder (SER)
Report
9.6.1
SER Triggering
The relay stores an entry in the SER report for a
change of state of any one of the elements listed
in the SER trigger setting as outlined in
Section 4.9.1, page 72.
The relay adds a message to the SER to indicate
power up or settings change conditions:
relay newly powered up or settings changed
Each entry in the SER includes SER row number,
date, time, element name or defined alias, and
element state.
9.6.2
SER Trigger Condition
Aliases
You may rename any of the SER trigger
conditions using the SIMPRO-100 Relay ALIAS
settings. The relay permits up to 20 aliases to be
assigned to conditions that trigger SER row
entries. For instance, the factory default logic
settings define contact input IN5 for operation as
an Emergency Restart input. Factory default alias
setting 15 renames input IN5 for reporting in the
SER:
ALIAS15 = IN5 EMERGNCY_RSTART PICKUP DROPOUT
When input IN5 is asserted, the SER report will
show the date and time of
EMERGNCY_RSTART PICKUP
. When input IN5 is
deasserted, the SER report will show the date
and time of
EMERGNCY_RSTART DROPOUT
. With this
and other alias assignments, the SER record is
easier for the operator to review. See
Section 4.9.2, page 73 for additional details
regarding the alias settings.
