Webthree-phase alternator Gigatop. 4-pole stator winding power plant. Power in kVA: 950,000 kVA - 2,235,000 kVA. Voltage: 22 kV - 26 kV. Supply frequency: 50, 60 Hz. The world’s most powerful water-cooled generator in operation (1,755 MW) GE’s Gigatop 4-pole generator is the right solution for your nuclear power plant. WebMar 7, 2024 · An induction generator produces electrical power when its rotor is turned faster than the synchronous speed. For a typical four-pole motor where there are two pairs of poles on a stator operating on a 60 Hz electrical grid, the synchronous speed is 1800 rotations per minute. The same four-pole motor operating on a 50 Hz grid will have a ... new west cardiology
