Product Description

Process Bus

Support of IEC 61850-9-2 and IEC 61850-9-2LEstreams

  • IEC 61850-8-1 GOOSE, MMS and process bus client protocol on the same module
  • Test- and Simulation Bit support
  • Sample synchronization for mixed configurations of direct connected instrument transformers and sampled measured values via IEEE 1588v2/PTP
  • Mixed configurations of CIT and SMV

Benefits of process bus

  • Cost saving - Copper cable reduction, faster installation and commissioning
  • Independency - Interoperable design enables multi-vendor solutions based on IEC 61850 standard
  • Flexibility and scalability - Easier adaptation to future requirements and integration of wider range of data sources (independent signal routing)

The use of non-conventional transformers (LPIT) makes the process bus solution even more efficient.

  • Cost saving - Reduced space and 90 % reduced weight of transducers
  • Cost saving - One LPIT type for protection and measurement in all feeders because of the wide dynamic range
  • Operational safety - Danger of open CT circuits obsolete or reduce 

Benefits of Siemens process bus solution

  • Adoptable to multiple CT, VT, LPIT inputs
  • Scalable number of binary inputs and outputs
  • Expendable by a 2nd row
  • Direct high speed tripping of circuit breaker < 1 ms
  • Collection of additional data (temperature, pressure, tap changer positions)
  • Cyber security in accordance with NERC CIP and BDEW Whitepaper requirements
  • Highest availability even under extreme environmental conditions  by conformal coating of electronic boards
  • Merging Unit functionality is available for all modular SIPROTEC 5 protection relays
  • Merging Unit SIPROTEC 6MU85 supports backup protection functionality and redundancy concepts
