Digital Fault Recorder, SIMEAS R-PMU, Manual
E50417-H1076-C360-A5, Release 10.2012
7.2.2.2 Trigger Functions
Several trigger limits and recording times can be parameterized for the Transient Phasor
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 extended (retriggered) up to the maximum recording
time by a repeated limit value violation. The recording time is 900 s per TPR fault record (50 Hz
nominal frequency) and 750 s (60 Hz nominal frequency) plus prefault time.
Please see tables 7-17 and 7-18 below for the values to be triggered to by the Transient Phasor
Recorder depending on the acquisition modules.

connection (dt is the filter time for the TPR)
