On the protection relay LHMI go to -> Main Menu/Configuration/Time/Synchronisation
– PTP priority 1 = 128
– PTP priority 2 = 128

If both, Master and Backup master clocks fails, the protection relays establish a new
primary source for time synchronization information automatically.
Check time synchronization status at the voltage sender protection relay.
