Filed: 1919-04-10
Abstract: 155,858. Electrical Improvements, Ltd., and Beard, J. R. April 10,'1919. Phase, changing.-In an electric supply system using multi-phase low frequency current a higher frequency current of relatively small magnitude is superposed cn the low frequency current in order to make it suitable for lighting, the multiphase currents being used without alteration for power devices such as motors. As shown, a single-phase motor-driven generator J supplies tc the neutral wire H a current of three times the frequency of the three-phase generator D. Motors M. K, &c. are connected across the threephase mains E, F, G, the current not being modified. Lamps L are connected across the neutral H and the phase leads, the current to the lamps being of the fundamental frequency, but with the wave changed from a sine form to a flat-topped wave. Instead of an alternator J a static frequency converter may be used to supply the single-phase current. Instead of being connected to the main distributing system the invention may be applied to a subsidiary circuit connected to the main system by a transformer.
