Selection of Timezone and Synchronisation Protocol
The protection relay masters both UTC and local time. This means that the device can be synchronised with UTC time
while using local time for user display.
Time Synchronisation with UTC time (recommended):
Time synchronisation is usually done using UTC time. This means for example that an IRIG-B time generator is sending
UTC time information to the protection relay. This is the recommended use case, since here a continuous time
synchronisation can be ensured. There are no "leaps in time" through change of Daylight Savings Time.
To achieve that the device shows the current local time, the timezone and the change to Daylight Savings Time can be
configured.
Please carry out the following parameterization steps under [Device Para/ Time]:
1.Select your local timezone in the timezone menu.
2.There also configure the switching of daylight savings time.
3.Select the used time synchronisation protocol in the TimeSync menu (e.g. "IRIG-B").
4.Set the parameters of the synchronisation protocol (refer to the according chapter).
Time Synchronisation with local time:
Should the time synchronisation however be done using local time, then please leave the timezone to » UTC+0
London« and do not use switching of daylight saving time.
Without Time Synchronisation:
To achieve that the device shows the current local time, the timezone and the change to Daylight Savings Time can be
configured.
Please carry out the following parameterization steps under [Device Para/ Time]:
5.Select your local timezone in the timezone menu.
6.There also configure the switching of daylight savings time.
7.Select » manual« as your used protocol in the TimeSync menu.
8.Set date and time.
The synchronisation of the relay´s system time is exclusively done by the
synchronisation protocol selected in the menu [Device Para/ Time/ TimeSync/
Used Protocol].
