Operation principle

Disturbance report DRPRDRE is a common name for several functions to supply the operator,
analysis engineer, and so on, with sufficient information about events in the system.
The functions included in the disturbance report are:
• Event list
• Indications
• Event recorder
• Trip value recorder
• Disturbance recorder
Figure 101
Event list, Event recorder and Indications uses information from the binary input function blocks
(BxRBDR). Trip value recorder uses analog information from the analog input function blocks
(AxRADR). Disturbance recorder DRPRDRE acquires information from both AxRADR and BxRBDR.
