Time synchronization

The IED has an internal real-time clock which can be either free-running or
synchronized from an external source. The real-time clock is used for time stamping
events, recorded data and disturbance recordings.
The IED is provided with a 48-hour capacitor back-up that enables the real-time clock
to keep time in case of an auxiliary power failure.
Setting Synch Source determines the method how the real-time clock is synchronized.
If set to "None", the clock is free-running and the settings Date and Time can be used
to set the time manually. Other setting values activate a communication protocol that
provides the time synchronization. Only one synchronization method can be active
at a time but SNTP provides time master redundancy.
