4.4 Time Synchronization
Time synchronization is an important feature of the SIMEAS R-PMU and must be performed with
high precision. The phasor measurements in particular, require precise time stamping.
An exact time synchronization (<5 µs) of all devices is necessary, in order to ensure that the
records of fault recorders in different locations can be compared to each other.
Time synchronization of SIMEAS R-PMU devices can be implemented by using either:
DCF77 signal of a GPS clock
Modified DCF77 signal of a Sync-Box
Minute pulse
Note
The time synchronization function is parameterized using the parameter setting interface of
OSCOP P. The GPS clock must be parameterized separately (See Chapter 8).
