• A Power Company Communication System

Publication Year: 1935, Page(s):262 - 265
| | PDF (2775 KB)

By interconnecting and co??rdinating its private communication facilities with the commercial telephone system, the Tennessee Electric Power Company is building up a comprehensive communication system for the use of all departments of the company. These improved communication facilities are described briefly in this paper. The principal features of the plan are: (1) adequate interconnecting facili... View full abstract»

| | PDF (1123 KB)

The application of dimensional analysis to various types of problems in electrical engineering is discussed in this paper for the purpose of stimulating the use of model experiments in solving these problems. The authors hold that this method can be applied to many electrical engineering problems that are difficult of solution otherwise. Criterions for determining whether or not dimensional analys...

| | PDF (2077 KB)

Recent developments in a bridge devised at Massachusetts Institute of Technology for obtaining high-precision power-factor measurements on small oil samples, and the associated oil cell, are described in this paper, and the results of measurements on oil samples are discussed. Several conclusions drawn from the work done at M.I.T. on power factor bridges and measurements are given. View full abstract»

• A Wattmeter for Communication Circuits

Publication Year: 1935, Page(s):279 - 281
| | PDF (649 KB)

An attempt has been made to devise a different type of wattmeter for measuring power and power factor in a-c circuits such as those found in communication service. An adjustable network has been constructed in such a manner that when it is balanced in 3 operations the power factor is indicated directly and the power can be obtained by a short and simple sliderule calculation.

• Some Characteristics of A-C Conductor Corona

Publication Year: 1935, Page(s):282 - 292
Cited by:  Papers (6)
| | PDF (8313 KB)

Corona discharges from a-c conductors are characterized by marked polarity effects. The most pronounced electrical polarity effect is the sudden burst of negative corona current each cycle, which sets up high frequency oscillations that produce electromagnetic radiation throughout the radio frequency spectrum. Polished and smooth weathered cables produce such radiation only during negative half cy... View full abstract»

• Methods of Electrical Prospecting

Publication Year: 1935, Page(s):293 - 296
| | PDF (1971 KB)

Electrical methods of prospecting are becoming increasingly important as the search for hidden deposits of ore extends deeper and deeper below the surface of the earth. Electrical prospecting is not limited to this use, however; it has found many valuable applications in engineering and in geology. The 4 general methods of electrical prospecting are described briefly in this paper. View full abstract»

• Inductance of Steel Re??nforced Aluminum Cable

Publication Year: 1935, Page(s):296 - 299
Cited by:  Papers (1)
| | PDF (1066 KB)

Calculated values of inductance of steel re??nforced aluminum cable, presented in this paper, show that previously published values of inductance obtained experimetally are in error by amounts ranging up to 5 per cent. Furthermore, all these errors are on the low side, that is, the unsafe side from the standpoint of the design engineer. View full abstract»

• Saturated Synchronous Reactance

Publication Year: 1935, Page(s):300 - 305
Cited by:  Papers (14)
| | PDF (1970 KB)

It is well known that the effects of magnetic saturation are important in modifying the operating characteristics of synchronous machines. In this paper is shown a method of accurately taking into account these effects on the balanced steady-state operation of a cylindrical rotor synchronous machine by using a saturated value of the synchronous reactance. The expression for this reactance. is deri... View full abstract»

• A New Source of Kilocycle Kilowatts''

Publication Year: 1935, Page(s):305 - 307
| | PDF (2188 KB)

Many applications of kilocycle kilowatts'' (electric power at frequencies of 1,000 to 100,000 cycles per second) have not been feasible because of the high cost of equipment for generating such power. In this paper, a new source of kilocycle power employing an electronic tube called the arc tube is described. The cost of the arc tube and its associated equipment is lower than that of other sourc... View full abstract»

• Precise Speed Control for D-C Machines

Publication Year: 1935, Page(s):307 - 312
Cited by:  Papers (1)
| | PDF (1468 KB)

In this paper a circuit is described that holds the average speed of a d-c shunt-wound machine as constant as the standard reference used (for which the most precise standard known can be employed) and holds the instantaneous speed very close to standard speed if there are not sudden changes of load or applied voltage. The machine is positively indexed in phase with respect to the standard. In add... View full abstract»

• Calculations for Coreless Induction Furnaces

Publication Year: 1935, Page(s):312 - 315
Cited by:  Papers (7)
| | PDF (726 KB)

Calculations of electrical characteristics of coreless induction furnaces usually are made by means of the penetration formula (equation 18 in this paper), this formula, however, gives only an approximation which is fairly accurate only at relatively high frequencies. As a wide range of frequencies can be used in these furnaces, there is a need for calculations that are good at any frequency; to m... View full abstract»

• Sparking Under Brushes of Commutator Machines

Publication Year: 1935, Page(s):315 - 321
Cited by:  Papers (5)
| | PDF (3522 KB)

Sparking under the brushes of commutating machinery has been investigated in considerable detail, for the purpose of studying and analyzing the various factors which cause sparking. Among the conclusions reached are that in a detailed consideration of sparking phenomena both current density and rate of change of current density must be taken into account. View full abstract»
