[D8935AAQ], Letter from William J Jenks to Thomas Alva Edison, April 8th, 1889



Edison Electric Light Co####Thomas A. Edison, Esq., Orange, N.J, Dear Sir:--####Mr. Johnson has thus far preferred that nothing should be said definitely regarding our ability to transform from high to low potential for central station work until we received your assurances that apparatus could be given at short notice.####Aside from the special application, about which we consulted you some weeks ago relative to the transmission of power, there has come a demand for direct current rotary transformers from 1000 volts to 100, and one of the agents of the United Company will call here to-morrow (Tuesday) to secure definite information as to whether we can promise him a transformer of this kind of a capacity of 500 16 candle power lamps, within three months. If he can secure this assurance he can immediately close a Municipal plant, and in doing so sell a dynamo on the basis of this increased output in addition to the Municipal lighting which is desired, low pressure lamps to be located about three miles from the source of power.####Please give us definite information if you can, and also the efficiency of a transformer upon which we can estimate the sizes of conductors and approximate cost of installation.####Will it be safe to estimate the first cost of small transformers of this kind at as low a price as a dynamo of equal watt capacity?####Yours very truly, W.J Jenks, Director####[name mentions: Edison United Manufacturing Co., E.H Johnson.
