No regulation of the excitation means:

No regulation of the Power Factor (direct)

No regulation of the Voltage

Over Voltage proport ional to the over speed

No isolated operation possible

The ECOBulb unit is adapted to the integration into an existing strong

and stable electrical network, in Europe, North America,

High Turbine eff iciency

Very high Generator efficiency at full and part load

No step - up Gear nor lubr ication system

Very compact unit thanks to the complete integration of the

Turbine and Generator

The ECOBulb unit is the result of putting together the

competences inside of ANDRITZ HYDRO for a Compact Hydro

development
