Trigger Functions - Siemens SIMEAS R-PMU Manual

7.2.1.2 Trigger Functions

Several trigger limits and recording times can be parameterized for the Transient Analog
Recorder. The input signals are analyzed according to the trigger conditions and start the fault
recording if the trigger condition is met. The duration of the fault record depends on the
parameterized recording times and can be prolonged by a repeated limit value violation
(retriggering) within the recording time. The recording time is limited to a maximum of 30 s plus
1 s prefault time for each TAR fault record.
The tables 7-11 and 7-12 show the values that the Transient Analog Recorder can trigger to,
depending on the data acquisition modules (the powers in the CDAU column are applicable only
for coupled CDAUs).
