Build full digital substations with SIPROTEC

Siemens offers new Merging Unit SIPROTEC 7SC805 for conventional instrument transformers. This device allows conversion of existing substations to process bus substations without change in the primary equipment.
This approach reduces cable complexity, simplifies workflows, and makes both new and existing systems – especially those with conventional converters – extremely economical and secure.

To guarantee interoperability and future viability, the innovative process bus solutions from Siemens are, of course, certified according to IEC 61850-9-2 and IEC 61850-8-1. GOOSE messages (IEC 61850-8-1) allow primary equipment control command functions additionally.

The integrated PRP and HSR protocol assures reliable and secure communication.

Power. Flexible. Easergy.
