| | PDF (2224 KB)

In Part I it is shown how, from the integral of the general differential equation of the electric circuit, which has been discussed in a previous paper, all the types of electric currents are derived as special cases, corresponding to particular values of the integration constants. The equations of the circuits with massed constants, that is, the usual electric circuits, are derived by substitutin... View full abstract»

| | PDF (766 KB)

The paper shows how a voltmeter which will read directly the maximum or crest values obtained in high-voltage testing may be constituted by a combination of an electrostatic voltmeter and an electric valve. Diagrams of connection are shown and results of test given to indicate the validity of the method. View full abstract»

• ### The Crest Voltmeter

Publication Year: 1916, Page(s):109 - 116

| | PDF (1170 KB)

The demand for testing dielectric media in terms of crest voltage has resulted in several schemes of measuring high voltage. The paper mentions and compares some of the methods of high-voltage measurement and describes in more detail the crest voltmeter which has been found to be more satisfactory in commercial testing than the spark gaps which have been adopted by the Institute in the Standardiza...

• ### Notes on the Measurement of High Voltage

Publication Year: 1916, Page(s):119 - 146
| | PDF (4737 KB)

A briet account is given of some experiments made to determine mine the relative accuracy of certain methods used in measuring high voltages. The methods comprise the use of a tertiary (or voltmeter) coil in the high-tension transformer, the direct measurement of voltage by a crest voltage meter and the derivation of the high-tension pressure from the primary voltage.

• ### Operation on the Norfolk & Western Railway

Publication Year: 1916, Page(s):147 - 166
| | PDF (2926 KB)

This paper describes the great advantages, from an operating standpoint, incident to the inauguration of electric service on the Elkhorn grade of the Norfolk & Western Railway Co. and why it is possible almost to double the capacity of the road by the use of 12 electric locomotives, instead of the 33 Mallet locomotives formerly in service.

• ### Chattering Wheel Slip in Electric Motive Power

Publication Year: 1916, Page(s):175 - 182
| | PDF (1689 KB)

The paper shows that chattering wheel slip is characteristic of all types of electric motive power. The application of the motive power in the electric and steam drives is compared, and the reasons for the chattering wheel slip and the means of measuring and rectifying the same are given.

• ### A Method of Determining the Correctness of Polyphase Wattmeter Connections

Publication Year: 1916, Page(s):183 - 211
| | PDF (2603 KB)

The object of this paper is to describe a method of checking the correctness of the connections of a polyphase watt-hour meter on a three-phase circuit; and to show that the methods most commonly used for this purpose are unreliable. Polyphase wattmeters are classified according to the number of their voltage terminals and expressions giving the amount of energy theoretically registered by the met... View full abstract»

• ### The Future of Water Power in the United States

Publication Year: 1916, Page(s):249 - 260
| | PDF (1249 KB)

This paper gives a careful compilation of figures showing the total fixed installed primary power in the United States and similar figures for total installed water power, at the same time calling attention to the unreliability of statistics in general. With these figures, those compiled by the Commissioner of Corporations are summarized and compared. The geographic distribution of installed water... View full abstract»

• ### Iron Losses in Direct-Current Machines

Publication Year: 1916, Page(s):261 - 299
| | PDF (3949 KB)

The term iron loss, as used in connection with rotating machinery, is shown to cover a large number of losses, some of which actually do not lie in the iron itself. The term core loss should be used except when the losses are actually located in the iron itself. It is shown that no great accuracy is practicable in the calculation of the actual iron losses, except in special instances, due to the f... View full abstract»

This paper describes experimental work done to determine the co-efficient of corrosion of iron and lead in soil with varying frequencies of alternating or reversed current with 60 cycles per second as the highest frequency and a two-week period as lowest?? some d-c. tests being made as a check on the methods. The results show (1), that a decrease of corrosion occurs with an increase in frequency; ... View full abstract»
