Figure 285: Disturbance report structure
Up to 100 disturbance reports can be stored. If a new disturbance is to be recorded
when the memory is full, the oldest disturbance report is overwritten by the new
one. The total recording capacity for the disturbance recorder is depending of
sampling frequency, number of analog and binary channels and recording time and
settings information. Figure
286 shows the number of recordings versus the total
recording time tested for a typical configuration, that is, in a 50 Hz system it is
possible to record 100 where the average recording time is 3.4 seconds. The
memory limit does not affect the rest of the disturbance report (Event list (EL),
Event recorder (ER), Indications (IND) and Trip value recorder (TVR)).
