XAMPLE TANDARD
The following example standard 15-cycle event report in Figure 12.4 also corresponds to the
example sequential events recorder (SER) report in Figure 12.8. The boxed numbers in
Figure 12.4 correspond to the SER row numbers in Figure 12.8. The row explanations follow
Figure 12.8.
In Figure 12.4, the arrow (>) in the column following the V1Mem column identifies the "trigger"
row. This is the row that corresponds to the Date and Time values at the top of the event report.
The asterisk (*) in the column following the V1Mem column identifies the row corresponding to
the "fault" values listed in the event summary report. See Currents and Voltages on page 12-6.
The phase current is calculated from the row identified with the asterisk and the row one quarter-
cycle previous (see Figure 12.4 and Table 12.1). These currents are listed at the end of the event
report in the event summary. If the "trigger" row (>) and the faulted phase current row (*) are
the same row, the * symbol takes precedence.
