To protect the SA system from signals with a high change rate that can easily saturate
the EVENT function or the communication subsystems behind it, a quota limiter is
implemented. If an input creates events at a rate that completely consume the granted
quota then further events from the channel will be blocked. This block will be
removed when the input calms down and the accumulated quota reach 66% of the
maximum burst quota. The maximum burst quota per input channel is 45 events per
second.

16.6.2 Functionality
Complete and reliable information about disturbances in the primary and/or in the
secondary system together with continuous event-logging is accomplished by the
disturbance report functionality.
Disturbance report DRPRDRE, always included in the IED, acquires sampled data of
all selected analog input and binary signals connected to the function block with a,
maximum of 40 analog and 96 binary signals.
The Disturbance report functionality is a common name for several functions:
