In a hydroelectric power plant, water is lifted into a reservoir by an electric pump so that it can later be used to generate electricity. The stored water then drives the turbine and generates electricity.
Compressed air is used to remove excess water from the pump chamber to ensure that the pump starts without any strain. The TVZ 900 is used for this, which compresses atmospheric air to 36 bara and thus ensures efficient draining.
