3.2.
Disturbance recorder
The disturbance recorder can be used to record all the
measured signals, that is, currents and the status information
of digital inputs (DI) and digital outputs (DO).
Triggering the recorder
The recorder can be triggered by any start or trip signal from
any protection stage or by a digital input. The triggering signal
is selected in the output matrix (vertical signal DR). The
recording can also be triggered manually. All recordings are
time stamped.
Reading recordings
The recordings can be uploaded, viewed and analysed with the
VAMPSET program. The recording is in COMTRADE format.
This means that also other programs can be used to view and
analyse the recordings made by the relay.
For more details, please see a separate VAMPSET manual.
Number of channels
At the maximum, there can be 12 recordings, and the
maximum selection of channels in one recording is also 12
(limited in waveform recording). The digital inputs reserve one
channel (includes all the inputs). Also the digital outputs
reserve one channel (includes all the outputs). If digital inputs
and outputs are recorded, there will be still 10 channels left for
analogue waveforms.
