3.6.1.2 Functionality
The protection relay has a disciplined RTC in hardware with a resolution of
one nanosecond. The clock can be either free-running or synchronized to an
external source. The RTC is used to time-stamp events, recorded data, disturbance
recordings, sampled measured values and various other system services.
The protection relay supports SNTP, IRIG-B, IEEE 1588 v2, DNP3, Modbus,
IEC 60870-5-101/104, IEC 60870-5-103 and line differential communication to
synchronize the RTC. IEEE 1588 v2 with a GNSS grandmaster clock and IRIG-B
provide the accuracy of ±1 μs. The accuracy is ±1 ms with SNTP.
