268 Digital Fault Recorder, SIMEAS R-PMU, Manual
E50417-H1076-C360-A5, Release 10.2012
Transient phasor recorder (TPR)
A fault record that has been recorded contains signal tracks for AC values, phase angles,
symmetrical components, active and reactive power, frequencies, process and binary signals.
General data
 Recording rate: 1 to 5 nominal cycles
 Resolution of the binary changes: 1 kHz and a maximum of 250 changes per second and
DAU
 Recording of the history: up to 30 s at 50 Hz and up to 25 s at 60 Hz before the occurrence
of the fault
 Recording time:
via OSCOP P parameterization, 900 s max. at 50 Hz, 750 s max. at 60 Hz
separate setting for manual or logical trigger
in the case of an external triggering at the binary input: for the duration of the pending
external signal (900 s max. at 50 Hz, 750 s max. at 60 Hz)
Recorded values of the DAUs
Note: Recorded values in {...} are applicable for coupled CDAUs. The current inputs of the
CDAU are coupled to a voltage group, e. g., a VDAU or VCDAU, for power measurement
.
Configurable trigger functions
Level trigger min/max:
Monitoring of the analog measured values for observance of min/max limit values. Triggering
is started as soon as the measured value exceeds or falls below the parameterized limit
value.
