Disturbance recorder
The disturbance recorder can be used to record all measured
signals i.e. currents and voltages, status information of digital
inputs (DI) and digital outputs (DO). The digital inputs include
also the Arc light information (S1, S2 and Arc binary input BI).
The digital outputs include the Arc binary output information
(BO).
Recorder capacity is 48 000 bytes. There can be a maximum of
5 recordings and the maximum selection of channels in one
recording is 12 (limited in waveform recording).
The recorder can be triggered by any protection stage start or
trip signal, Arc sensors (S1, S2, BI) and digital input. The trig
signal is selected in the output matrix. The recording can also
be triggered manually.
When recording is made also the time stamp will be
memorized.
The recordings can be viewed by VAMPSET program, version
8.x or newer. The recording is in COMTRADE format so also
other programs can be used to view the recordings.
For more detailed information, see separate Disturbance
Recorder manual VMDR.EN0xx.
