Migration of existing substations
The SWT 3000 also demonstrates its high degree of flexibility when existing substations are migrated to protection devices via the IEC 61850 communications standard. The SWT 3000 has all necessary command interfaces – both as binary interfaces and as GOOSE. This always keeps investment costs economically manageable, because the substations can be updated step by step for a new network age
SWT 3000 as a binary command interface
The Siemens SWT 3000 with bidirectional individual channels for direct, permissive or blocking applications, offers the connection of traditional distance protection devices based on binary input and output commands.
SWT 3000 for IEC 61850 (GOOSE)
When distance protection is already operating with IEC 61850 interfaces, GOOSE commands can be transmitted via SWT 3000 from substation to substation via electrical or optical ports.
