Abstract: The present invention generally relates to hydraulic machinery, such as hydraulic turbines. More specifically, the invention is directed to optimizing power consumption when the turbine is used in condenser mode. The present invention provides a novel hydraulic installation where the reduction of pressure in the spiral case during condenser mode operations is more efficient, limiting the power consumption if compared to state-of-the-art installations.
