There are two cylinders (tandem) assembled one after the other; a cylinder with high pressure (12 kg/cm 2) and a cylinder with low pressure (5 kg/cm 2); the cylinder with low pressure uses the steam of the cylinder with high pressure (compound).
The generator or dynamo produces D.C. current for the oldest part of city (ACEC 575 kW – 230 V – 2500 A).
The alternator produces AC current with electromagnets assembled in the wheel (ACEC 600 kVa – 10 kV – 34,6 A ster).
The AC current was used in the suburbs (this already since 1923 with a former steam engine).
High voltage had been used since 1950 and henceforth the steam engines were only used during peak hours. One definitively stopped them in 1966. |
