IRIG-B
IRIG-B is available in all 8 Series relays. A failure on IRIG-B triggers an event and a target
message.
FAST PATH:
Note that IRIG-B is auto detected. The signal type is detected in the hardware, so there are
no configurable options.
SNTP Protocol 850 Feeder Protection System relays accept time synchronization from up to two different
SNTP servers. In order to define number of SNTP servers to be used, different settings for
each SNTP server must be configured.
• If one SNTP server is used to synchronize the relay, the SNTP Server and UDP port
settings must be configured with the corresponding settings.
• If two SNTP servers are used to synchronize the relay, the SNTP Server IP and UDP port
for the main server must be configured, along with the SNP Server 2 IP and UDP port
for the back-up server.
NOTE
NOTE:
850 Feeder Protection System relays only support SNTP unicast.
It may take 2-3 minutes for the relay to synchronize with the SNTP server.
