SMITH (Increased efficiency in the distribution of power is in line with the present need for full utili-zation of all electric power resources. Following is a description of a new arrangement in thecity of Seattle, written by the engineer of outside construction on the Seattle Municipal Light& Power System.—The Editor.) Some radical changes are to be made in the citydistributing system of the Seattle municipal plant asrapidly as present plans can be carried out. Some ofthe features proposed are different from anythingused in any city in the country. The proposed changes, in brief, consist in chang-ing a 15,000-volt, 2-phase system to 3-phase with15,000 volts to neutral, and the extension of this. Chart showing current used by district which has been changed to new system system into each district now served by primary,with the shortening of the primary feeder to a max-imum of two or three thousand feet and consequentelimination of the feeder regulator. The idea is tosubstitute a high voltage system for the long pri-mary feeders, and so subdivide the primary districtsthat the customer at the feeding point of the districtnearest the station will receive the same voltageas the one at the extremity of the most remote dis-trict, within the three or four-volt variation permis-sible on the tungsten lamp. Details of the New Plan To illustrate, let us take a typical primary dis-trict, such as the University section, and trace thecurrent from generating station to customer on theold and the new plans of distribution. The districtuses 750 kilowatts at 120-240 volts single phase forlight with about 100 kilowatts of polyphase power—a total of 800 kw. on the lightin
