Hydroelectric power plant of St. Anton (Italy) -  Synchronization of the generators with the grid

TROYER AG, which is implementing the entire electromechanical equipment for the hydroelectric power plant, has decided on MV distribution systems from Siemens. High switching capacity and small space requirements are needed: The VB1 generator circuit-breaker is the perfect solution for multiple connected supply systems. Siemens was able to provide a customized solution that met the challenges of the installation.

Product information

Versatile, comprehensive and flexible switchgear for paralleled generation units

Can be customized to your specific requirements: The VB1 generator switchgear is highly flexible and has an expandable modular concept, making it ideally suited to the power range up to 140 MW. These features make it especially attractive for power plants with multiple generators or auxiliary feeders for in-house use, excitation or break disconnectors. Because they require a great deal of switching capability and available space, they are often used in hydroelectric power plants and retrofit projects.

Compact and safe: Discover the advantages

  • Highly flexible, expandable modular concept
  • Highly compact and customizable design
  • Suitable for indoor and outdoor installation
  • Suitable for multiple generators and auxiliary feeders
  • Arc fault-tested, operating availability to LSC 2A
  • High personal and operating safety
  • Maintenance-free
