6HTXHQFH QXPEHU
Normally, this setting option is seldom used. Each disturbance is assigned a number in
the disturbance report. The first disturbance each day normally receives 6HTXHQFH1R
. The value of 6HTXHQFH1R that can be read in the service report is the number that will
be assigned to the next disturbance registered during that day.
In normal use, the sequence number is increased by one for each new disturbance until
it is reset to zero each midnight.

The different recording times for the disturbance report are set (the pre-fault time, post-
fault time, and limit time). These recording times affect the disturbance recorder and
event recorder functions. The total recording time, tRecording, of a recorded distur-
bance is:
tRecording = tPre + tFault + tPost, or tPre + tLim, depending on which criterion stops the
current disturbance recording.
