Figure 472: 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 from 0-999.
