Figure 240: 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 sequential of events 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

Figure 241: 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 60 Hz system it is possible to record 80 where the

maximum recording time is 3.4 seconds. The memory limit does not affect the rest of the

disturbance report (Sequential of events, Event recorder, Indications and Trip value recorder).
