摘要:

In this paper the authors' aim is to give an outline of a system of analysis of the costs of electricity supply, which is suitable for use by a large undertaking giving supply under very varied conditions to consumers of many different types.The system described has been evolved during the last eight years, in connection with the undertakings of the New-castle-upon-Tyne Electric Supply Co., Ltd., and its subsidiary companies, and though it has not necessarily reached its final development it has at any rate passed beyond the purely experimental stage.The paper gives an outline of the method of analysis of all costs and capital charges, but deals in greater detail with those involved by the smaller classes of consumers, the supply to whom is receiving so much attention at the present time.A complete example of an analysis is included to illustrate the method of working.The paper is divided into the following sections:-(1) Reasons for cost analysis and the principles aimed at in the system described.(2) An outline of the method of analysis.(3) Data concerning characteristics of use of electricity by various types of consumers, required in order to apply the information obtained from the cost analysis, and the methods adopted to obtain these data.(4) Practical applications of the analysis

摘要:

The paper gives a general account of the suburban and main-line electrification scheme on the Great Indian Peninsula Railway. The first portion sets out the circumstances under which the scheme was initiated, the principal reasons for the decision to electrify the surburban and the main-line services, the actual and anticipated traffic, and the general programme of carrying out the work.The second portion deals with the local conditions which determined the design of a good deal of the plant and apparatus. This is followed by brief references to special points in the installation and design of the multiple-unit trains, electric locomotives, track equipment, bonding, substations, transmission system, power station, locomotive shops and car sheds, and system control. Such information as is available is given as to the capital cost of the complete scheme.The last two sections contain a number of statistics of operation and notes of operating experience, and the paper concludes with an Appendix in which are given for reference the names of contractors and principal sub-contractors, and the technical particulars of the plant supplied and installed.
