3.3 Sampling Rate
The disturbance recorder and the continuous disturbance recorder have independently
configurable sampling rate that can be set to: 1, 2 or 4 samples/cycle.
The binary inputs in the disturbance register are recorded with the same sapling rate as
the analog channels.
3.4 Trigger Burst Limiter
There is a user-configurable trigger burst limiter for the disturbance recorder which is
identical to the waveform recorder limiter Trigger Burst Limiter 1.4.
4 Trend Recorder
The trend recorder is responsible for recording minimum, maximum and average values
of RMS, DC measurement and active, reactive and apparent power.
The recording rate is the same as the Calculation period configured. And the duration of
the record is configurable from 1 to 24 hours.
5 SOE - Sequence of Events Records
The sequence of events recorder registers the status of the binary inputs, binary output
and GOOSE inputs. The recorder creates a XML file that groups the events according to
COMFEDE standard (IEEE C37.239-2010 Standard for Common Format for Event Data
Exchange).
The events in the SOE are recorded with accuracy better than 100µs.
The parameter “Aggregation Period” sets the duration of the records and time interval
that new records are created. The aggregation period can be configured from 1 – 1440
min.
5.1 Sampling Rate
The SOE sampling rate is the same sampling rate configured in the Waveform Recorder:
256 or 512 samples/cycle. In case the Waveform in not enabled in the configuration the
SOE recorder will use 256 samples/cycle as sampling rate.
6 Record Format and Naming, and Mass Storage Capacity
6.1 Record Format
Records are created in accordance with the COMTRADE standard IEEE C37.111-2013,
IEEE Standard Common Format for Transient Data Exchange for Power Systems . The
