Table 15 Interbay bus protocols
IEC 61850-8-1
IEC 61850-8-1 interbay bus supports
- Time synchronization viaSNTP:typical accuracy ±1 ms
- Two independent time servers are supported.Server 2 as
backup time
- Optical or electrical connection
- Differential current of each protection zone
- Monitoring information from REB500 central unit and bay unit
Binary events(signals, trips and diagnostic)
-Trip reset command
- Single connection point to REB500 central unit
-Disturbance recorder access via MMS file transfer protocol
.Export of ICD - file, based on Substation Configuration
Language SCL
LON
LON interbay bus supports
- Time synchronization: typical accuracy ±1 ms
