Figure 224: 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
225 shows the number of recordings versus the total recording
time tested for a typical configuration, that is, in a 60 Hz system it is possible to record
80 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)).
