Turbines and generators:
The power plant’s Francis spiral turbine has an impeller diameter of 1.45 metres. At a nominal flow rate of 8.6 m³/sec., it achieves a power output of 8,500 kW. The coupled 8,000 kVA three-phase synchronous generator works on a grid voltage of 6.3 kV. In winter, the waste heat of the generator is used to heat the machine hall; in summer, it is discharged to the outside via ventilation dampers in the window parapets.
In order to raise the generated electrical energy to 30 kV, the plant has an 8,000 kVA machine transformer. The electricity is conducted away to Öblarn and Trautenfels via two 30 kV branches into the regional supply grid of STEWEAG. The plant has a 200 kVA transformer for its own requirements.
