Time Synchronization
SNTP
SNTP
Important pre-condition: The protective relay needs to have access to an SNTP
server via the connected network. This server preferably should be installed
locally.
Principle – General Use
SNTP is a standard protocol for time synchronisation via a network. For this at least one SNTP server has to be
available within the network. The device can be configured for one or two SNTP servers.
The protection relay's system time will be synchronised with the connected SNTP server 1-4 times per minute. In
turn the SNTP server synchronises its time via NTP with other NTP servers. This is the normal case. Alternatively it
can synchronise its time via GPS, radio controlled clock or the like.
