Figure 204: Disturbance report functions and related function blocks
The whole disturbance report can contain information for a number of recordings,
each with the data coming from all the parts mentioned above. The event list function
is working continuously, independent of disturbance triggering, recording time, and
so on. All information in the disturbance report is stored in non-volatile flash
memories. This implies that no information is lost in case of loss of auxiliary power.
Each report will get an identification number in the interval from 0-999.

Figure 205: 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. In a 50 Hz
system it is possible to record 100 where the maximum recording time is 3.4 seconds.
