7.2.2.2.3 Cross Trigger
If the cross trigger has been activated for the Transient Phasor Recorder, recording by the
Transient Phasor Recorder will be started as soon as the Transient Analog Recorder has been
triggered. In this case, the prefault time corresponds to the recording time that has been
parameterized for the Transient Phasor Recorder. An extension (retriggering) of the TPR fault
record can only be initiated by the Transient Phasor Recorder and not by another cross trigger
of the Transient Analog Recorder.
7.2.2.2.4 Manual Triggers
There are several options for triggering the Transient Phasor Recorder manually. The duration
of the manually triggered fault record depends on the values parameterized under
Manual
recording time
and
Prefault time
. If a manual trigger is started, the SIMEAS R-PMU does not
send any network signal.
If a manual trigger starts a record, the record will be restarted if it is retriggered due to a
disturbance. Since the disturbance recording time is set independently of the manual trigger
recording time, this may change the total recording time.
Manual trigger on the control panel
Actuating the "Manual trigger" button on the control panel starts a fault recording.
Manual trigger via OSCOP P
Alternatively, the manual trigger can be started with OSCOP P. For detailed information on this
topic, see the OSCOP P manual, the chapter on
Transmitting data
.
7.2.2.2.5 External Trigger
For the Transient Phasor Recorder, the fault record can be started externally via a binary input
at the central processing unit of the SIMEAS R-PMU. Recording is continued as long as the
external control signal is provided. The recording time is limited to a maximum of 15 min plus
30 s prefault time at 50 Hz or 12.5 min plus 25 s prefault time at 60 Hz. If the external trigger is
set, SIMEAS R-PMU sends no network trigger signal.
If an external trigger starts a record, the record will be restarted if it is retriggered due to a
disturbance Since the disturbance recording time is derived differently than the external trigger
recording time, this may change the total recording time.
Note
The retrigger blocking time can be defined longer than the recording time to avoid unwanted
recording in the event of a wrong configuration.
