18.6.3 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 dependent on the operation of protective functions, and it can record
disturbances that were not discovered by protective functions for one reason or another.
Disturbance report can be used as an advanced stand-alone disturbance recorder.

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
distrubance records won't be deleted based on the memory consumption.
