Reporting
Event Reports, Event Summaries, and Event Histories
Within an event report, there are bracketed numbers at the left of the report (for
example, [11]) that indicate the cycle number.
The trigger row is indicated by a > character following immediately after the last
analog data column. This is the dividing point between the prefault or PRE time
and the fault or remainder of the data capture.
The relay indicates which row has the largest current magnitudes, which are
reported in the event summary, with an asterisk (*) character immediately after
the last analog data column. The (*) takes precedence over the > if both occur on
the same row in the analog section of the event report.
ERAQc (Analog Quantities)
To supplement the fixed analog quantities in the event report, select as many as
20 additional analog quantities in the event report. For example, say you pro-
grammed a function in the relay using Protection Math Variables PMV01–
PMV06, and you want to include these six PMVs in the event report. Enter the
six PMVs in the Event Reporting Analog Quantities as shown below.
The relay correlates the freeform line number chronologically with the ERAQc
quantities. In this example, ERAQ01 = PMV01, ERAQ02 = PMV02, etc.
In the event report, the ERAQ quantities follow the fixed analog quantities.
