15.6.3 Application
To get fast, complete and reliable information about disturbances in the primary and/or in the
secondary system it is very important to gather information on fault currents, voltages and events. It
is also important having a continuous event-logging to be able to monitor in an overview perspective.
These tasks are accomplished by the disturbance report function DRPRDRE and facilitate a better
understanding of the power system behavior and related primary and secondary equipment during
and after a disturbance. An analysis of the recorded data provides valuable information that can be
used to explain a disturbance, basis for change of IED setting plan, improve existing equipment, and
so on. This information can also be used in a longer perspective when planning for and designing
new installations, that is, a disturbance recording could be a part of Functional Analysis (FA).
Disturbance report DRPRDRE, always included in the IED, acquires sampled data of all selected
analog and binary signals connected to the function blocks that is,
• Maximum 30 external analog signals,
• 10 internal derived analog signals, and
• 352 binary signals
Disturbance report function is a common name for several functions; Indications (IND), Event
recorder (ER), Event list (EL), Trip value recorder (TVR), Disturbance recorder (DR) and Fault locator
(FL).
Disturbance report function is characterized by great flexibility as far as configuration, starting
conditions, recording times, and storage capacity are concerned. Thus, disturbance report is not

2.2.4 Increased the total number of recordings to 200 and events to 5000. Total number of
recordings (MaxNoStoreRec setting) is no longer configurable. MemUsed output is now
based on number of recordings to total number of recordings. Old disturbance records
won't be deleted based on the memory consumption.
