Siemens SIPROTEC 5 User Manual

The sampling frequency is a maximum of 16 kHz. This corresponds to 320 sampled values per nominal period
at 50 Hz and 266 sampled values at 60 Hz. Binary changes are recorded at a sampling rate of 4 kHz and a
resolution of 1 ms.
The flash memory of the device is automatically updated for every recording. If the flash memory is full, the
oldest recording is automatically overwritten when the device records a new fault record.
The pre-trigger and post-trigger time is set for all recorders. The recording starts as soon as the recorder is
triggered. The trip signal (trigger cause) can be again inactive during the recording (trigger clears). In this
case, the fault record is limited by the set parameters of the post-trigger time.
Four (4) different possible triggers are available for the fast-scan recorder:
•
Trigger from trigger routing
•
Manual trigger start
•
External trigger start
•
Triggers on indications
•
Trigger via IEC 61850 Controllable ( Start record )
You will find additional information about the Trigger via IEC 61850 Controllable in the chapters
7.3.3.4 Trigger Start Using Logic Block Chart and 7.3.3.3 GOOSE Trigger .

NOTE
For all trigger types except >Manual start , the parameters Pre-trigger time , Post-trigger
time and Maximum record time apply.
For the trigger type
>Manual start the parameter Manual record time applies.
Manual Start
Routing of the binary input >Manual start leads to a recording of fixed length. The length is set based on
the parameter Manual record time .
Triggering from Trigger Routing/External Start/Trigger on Indications/Trigger via IEC 61850 Controllable
With the routing of the binary input >External start , recording is performed as long as the signal is
present and the Post-trigger time is running. The running record ends as soon as the parameters
Post-trigger time or Maximum record time have reached the set values.
Mode
The fast-scan recorder operates only if Mode is set to on .
The recording is ended if Mode is set to off during the recording.
Recording Finished/Error Number
After the recording, the indication
Record made remains active for 2 s. The signal Fault number incre-
ments by 1 after each recording.
Retrigger Blocking Time
The retrigger blocking time can be activated separately for each triggered recorder. The retrigger blocking
time prevents retriggerings that lead either to a fault-record extension or to another recording.
The retrigger blocking time is started separately for each trigger source that is routed to a recorder.
Ring-Buffer Mode
While making a record on the flash memory, the device can determine whether the free space assigned to the
recorder in the recorder partition is too small. As a result of this, as many old records as needed are deleted –
starting with the oldest record – for the complete storage of the current recording. Deleting occurs even if the
record to be deleted is being read at the same moment by DIGSI 5 or a higher control level. In this case, trans-
mission is canceled.
