Conventional Power-generation

• The water drives the turbine

• The generator produces electrical voltage

• The voltage is stepped up in the transformer,
  since it is too low for it to be sent out direct
  to the grid.

Powerformer Concept

• What is new?
• Direct connection to the high voltage system
  (400kV)
• No step-up transformer
• No busbars
• No generator switchgear
• High voltage cables used for stator winding
