15.2 Time synchronization
15.2.1 Functionality
The time synchronization source selector is used to select a common source of
absolute time for the IED when it is a part of a control and a protection system. This
makes it possible to compare event and disturbance data between all IEDs in a station
automation system.
Micro SCADA OPC server should not be used as a time
synchronization source.
