The hydroelectric power station that has been described is in the Bergisches Land, at Kräwinklerbrücke near Remscheid-Lennep. The film shows how by using a canal to cut off a loop in a river it was possible to make an incline available for a power station situated on the canal. A dam on the upper course of the Wupper stores up the water, which then flows into the upper canal leading to the power station. The water supplies potential energy in the turbines and flows back to the Wupper via the lower canal. The electric energy from the generators is conducted via overhead cables to the consumers. The hydraulic and electro-technical installations of the power station are shown, and the most important phases of operation as the station is starting up again after the upper canal has been emptied for cleaning: one sees the flooding of the upper canal, the way in which the rake is cleaned, a turbine serviced and the turbine chamber flooded, one also sees the servicing of the respective generator, the way in which he is started up, and the way in which the generator is synchronized and loaded. During synchronization the three characteristic values of the tension of the new generator which is being added, and the generator (or network) which is in operation already, have to be compared with each other individually. The active current of the generator is regulated by means of the "Fink'sche Drehschaufeln" of the turbine thus influencing the amount of liquid flowing through the turbine. The reactive current is regulated using the exciter. As this latter has neither commutating poles nor a compensation winding, the brush apparatus has to be adjusted if the regulation of the current is altered. This is done in order to avoid the brushes firing.
