The functions included in the disturbance report are:
• Event list (EL)
• Indications (IND)
• Event recorder (ER)
• Trip value recorder(TVR)
• Disturbance recorder (DR)
Figure 442 shows the relations between Disturbance Report, included functions and
function blocks. Event list (EL), Event recorder (ER) and Indications (IND) uses
information from the binary input function blocks (BxRBDR). Trip value recorder
(TVR) uses analog information from the analog input function blocks (AxRADR).
Disturbance recorder DRPRDRE acquires information from both AxRADR and
BxRBDR.

Figure 442: 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.
