Analyzing Events
Event Reporting
Other figures help in understanding the information available in the event
report current columns:
➤
shows how analog event report current column data
relate to the actual sampled current waveform and rms current
values.
➤
shows how analog event report current column data
can be converted to phasor rms current values.
Example 15-Cycle
Event Report
The following example of a standard analog 15-cycle event report in
also corresponds to the example SER report in
.
In
, an arrow (
>
) in the column following the
VCA
column would
identify 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
VCA
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
and
). 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.
