Abstract

279,841. Siemens - - Schuckertwerke Akt. - - Ges., (Assignees of Siemens. Schuckertwerke Ges.). Oct. 28, 1926, [Convention date]. Protective arrangements.-The neutral point of a generator or transformer 2 supplying mains 1 is earthed through a choking coil 3 of such a size that it together with the earth capacity of the main, indicated by the condensers 4, is in resonance with the fundamental frequency of the supply. In addition, other tuned circuits 5, 6 are shunted across the coil 3 so as also to produce resonance at two higher harmonics.
