Selection of Timezone and Synchronization Protocol
The protection relay masters both UTC and local time. This means that the device can be synchronized with UTC time
while using local time for user display.
Time Synchronization with UTC time (recommended):
Time synchronization 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
synchronization 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 synchronization protocol in the TimeSync menu (e.g. “IRIG-B”).
4.Set the parameters of the synchronization protocol (refer to the according chapter).
Time Synchronization with local time:
Should the time synchronization however be done using local time, then please leave the timezone to »
UTC+0
London« and do not use switching of daylight saving time.
The synchronization of the relay´s system time is exclusively done by the
synchronization protocol selected in the menu [Device Para/ Time/
TimeSync/ Used Protocol].
Without Time Synchronization:
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.
