Figure 200: 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.
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. The memory limit does not affect the rest of the disturbance report
(Event list, Event recorder, Indications and Trip value recorder).
The maximum number of recordings depend on each recordings
total recording time. Long recording time will reduce the number of
recordings to less than 100.
