The following example standard 15-cycle event report in Figure 12.2 (from a Model 0351xT
Relay) also corresponds to the example sequential events recorder (SER) report in Figure 12.5.
The circled numbers in Figure 12.2 correspond to the SER row numbers in Figure 12.5. The row
explanations follow Figure 12.5.
In Figure 12.2, the arrow (>) in the column following the
Freq
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
Freq
column identifies the row with the maximum
phase current. The maximum phase current is calculated from the row identified with the asterisk
and the row one quarter-cycle previous (see Figure 12.3 and Figure 12.4). These currents are
listed at the end of the event report in the event summary. If the “trigger” row (>) and the
maximum phase current row (*) are the same row, the * symbol takes precedence.
