Generator sets PZGW

22-355 kW

Product enquiry 

PZGW generator sets enable obtaining electricity from water generators and enable transmission of this energy to the existing power grid in the 22-355kW power range.



  • Nominal grid voltage: 3 x 400VAC@50Hz
  • Nominal power: 22-355 kW
  • Output power factor: cosφ = 1
  • Efficiency: η> 0.95 (excluding generator efficiency and coupling passive elements)
  • Total Harmonic Distortion: THD < 5%
  • Equipped with a voltage boosting system in the DC circuit of "boost" type
  • Work "on the network" with the possibility of autonomous "island work" ("off-grid")
  • nti Island Protection, that is, the possibility of automatic separation of the receiving network in the event of a power outage in the public power grid.
  • Short-circuit, over-/undervoltage, temperature, and voltage or phase loss protections; the occurrence of load asymmetry.
  • Mounting: in the control cabinet
