For LON communication the events normally are sent to station level at change. It is possibly also
to set a time for cyclic sending of the events individually for each input channel.
To protect the SA system from signals with a high change rate that can easily saturate the event
system 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
128 binary signals.
The Disturbance report functionality is a common name for several functions:
• Sequential of events
• Indications
• Event recorder
• Trip value recorder
• Disturbance recorder
The Disturbance report function is characterized by great flexibility regarding configuration,
initiating conditions, recording times, and large storage capacity.
A disturbance is defined as an activation of an input to the AnRADR or BnRBDR function blocks,
which are set to trigger the disturbance recorder. All connected signals from pickup of pre-fault
time to the end of post-fault time will be included in the recording.
Every disturbance report recording is saved in the IED in the standard Comtrade format as a
reader file HDR, a configuration file CFG, and a data file DAT. The same applies to all events, which
are continuously saved in a ring-buffer. The local HMI is used to get information about the
