Output and Regulation in Long-Distance Lines
TLDR
The object of the present paper is to discuss some of the features of the long line, more especially the line-output, regulation or voltage-variation, and the line energy-loss.Abstract:
The limitations of the power transmission line as to distance, power, and voltage, and its characteristics as to voltage-variation and energy-loss, have always excited a great deal of interest in the electrical art. The subject has been treated by a number of prominent engineers in its various phases, notable among these being Scott, Perrine, Steinmetz, and Mershon. These men and others have done pioneer work and have outlined the general limiting conditions of transmission. There are some of the relations and peculiarities of the long line, however, that are of importance and interest which have not, to the writer's knowledge, been clearly presented before electrical engineers. It is the object of the present paper to discuss some of these features, more especially the line-output, regulation or voltage-variation, and the line energy-loss.read more

Three-Phase Multiple-Conductor Circuits
Abstract: During the past year the subject of power transmission by multiple-conductor circuits has received considerable attention. The formulas and estimating curves given in the paper may therefore be of interest at this time. Formulas are developed for the inductance and capacitance to neutral per phase and the approximate corona starting voltage of perfectly transposed, multiple-conductor, three-phase transmission lines having any number of conductors per phase. For certain special arrangements of the conductors, curves are given for the 60-cycle reactance, capacity susceptance, and corona starting voltage. These curves show the effect of variations, throughout their practical range, in conductor diameter, spacing between phases and between conductors of the same phase. Two, three, four and five conductors per phase are considered. A comparison is made of multiple- and single-conductor circuits with respect to charging current, voltage at no load, power which can be carried with the same voltage drop, and stability.
