Abstract

The Association of Edison Illuminating Companies####New York, sept. 4th, 1889####Charles Batchelor####Dear Sir:####I enclose copy of the stenographer's notes of the discussion as to the Transformer. You will notice that the question of control of that type of apparatus at the sub-station from which the secondary circuits radiate was quite fully gone into, and that it was stated on Mr. Edison's authority that no such control had been provided for, but that a change of pressure in the secondary system, made necessary by the variation of load, must be effected by the goernment of the field magnets of the Minucipal dynamo at the power station. Mr. Edgar made it very clear that in any comprehensie system it would be desirable to place several motors, and perhaps more than one sub-station, on one feeder.####It will interest you in this connection to read Mr. Wirt;s paper on the relative efficiency of the three-wire, double three-ire (220 volts on each side) and the motor dynamo, with curves. All of these I enclose trusting that you will return the paper and diagrams as soon as convenient as they are to come up very soon for discussion here in the office.####It will be a matter of great interest to us in connection with this discussion if we can have your judgment as to the correctness of Mr. Wirt's premises.####Yours very truly, W.J Jenks, Secretary####[name mentions: Charles Edgar, W.J Jenks, Charles Wirt, Charles Batchelor, Association of Edison Illuminating Cos, Thos Edison]
