Application manual
The parameter SyncMaster defines if the IED is a master, or not a master for time
synchronization within a Substation Automation System, for IEDs connected in a
communication network (IEC61850-8-1). The SyncMaster can have the following values:
• Disabled
• SNTP -Server
Set the course time synchronizing source (CoarseSyncSrc) to Disabled
when GPS time synchronization of line differential function is used. Set
the fine time synchronization source (FineSyncSource) to GPS. The GPS
will thus provide the complete time synchronization. GPS alone shall
synchronize the analogue values in such systems.
