SWT 3000- teleprotection

Model: SWT 3000

The SWT 3000 Teleprotection system is the proven worldwide solution for identifying and isolating faults extremely quickly in the high-voltage grid.

 


The SWT 3000 Teleprotection system is the highly developed solution world wide for identifying and isolating faults extremely quickly in the high-voltage grid. Combined with existing distance protection relays, it allows operators to reduce downtime to an absolute minimum. The current stage of development is based on 50 years of practical experience and adaptation to changing challenges.

The SWT 3000 protection signaling system is extremely versatile. For example, it can use analog and digital networks as communications infrastructure. At the same time, it’s ideal for establishing substation-to-substation communication via IEC 61850.

 

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.

 

  • Keeps downtimes to an absolute minimum
  • Supports IEC 61850 interfaces as well as conventional binary interfaces
  • Flexible integration into various customer communications networks
  • Path protection via two different transmission routes for increased reliability
