Abstract :
In the annual report published in the October 1926 issue of the Institute´s JOURNAL our readers were informed that the mentioned Diesel generator of a capacity of 3175 kv-a. at 25 cycles and 125 rev. per. min. was, at present, the largest machine of its kind driven by a Diesel motor. Messrs. Siemens-Schuckert of Berlin-Siemensstadt now inform us that they have constructed much larger generators to be driven by Diesel engines. The largest Diesel set was put into service last year by the Hamburgische Elektrizitatswerke A.-G., of Neuhof, near Hamburg (Germany). A 15,000-h. p., 9-cylinder, Diesel motor, constructed by Messrs. Blohm & Voss, of Hamburg, in cooperation with the Maschinenfabrik Augsburg-Nurnberg, drives the largest three-phase generator of this kind. This was supplied by Messrs. Siemens-Schuckert and has a rated output of 13,000 kv-a. at 94 rev. per min. and 6300 volts. The set may be brought from a cold state to its full rated capacity within eight minutes. Full information regarding it is contained in the German Siemens-Zeitschrift, issue of January 1927 and in No. 3, (March issue) of the British Siemens-Schuckert Review. It will also appear later on in the Spanish Revista Siemens
