Figure 443: 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. Figure
444
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)).
