摘要:

In developing countries with high inner-city population density land prices for substation sites are extremely high. This article describes the merits of the transformer-feeder-substation concept as a low-cost, minimum-land-area solution for applications where simplicity, high service continuity and minimum maintenance are also primary considerations

摘要:

Aluminium smelters are very large consumers of both electricity and gas, and energy efficiency is absolutely vital. Today a modern smelter occupies a site outside Holyhead, and this factory is one of Europe's largest smelters. It consumes over 1800 million units of electricity a year which is supplied from a nuclear power plant

摘要:

If we consider electrical technology to be divided into the two main areas of information processing and energy processing, the pervasiveness of drives technology will be immediately apparent. In developed economies about one-third of all primary energy is converted into electricity, and about twothirds of this electrical energy is subsequently converted in electric motors and drives

摘要:

A low-cost hydroelectric plant was designed to operate during the rainy season on the Perak River when the flow exceeded the capacity of the existing small hydroelectric station. Original ideas and simple methods can result in low capital costs

摘要:

Gas chromatography has for long been used to analyse gases dissolved in insulating oil which are generated as fault conditions develop, but it is an expensive laboratory-based technique. A rugged low-cost continuous monitoring device known as the Hydran system has been developed, and has been exhaustively tested in field use in North America

摘要:

With potential annual savings in view of over £30 million, Ewbank Preece has been commissioned by The Energy Technology Support Unit to manage a demonstration project to improve the cost effectiveness of electric-motor drives. Originally restricted to industry, the project hasbeen widened to include the commercial and domestic sectors, and also single-phase and fractional high-performance motor drives

摘要:

System loss, namely the difference between electrical energy generated and actually sold, is very important, especially in the under-developed world. The article considers the various components of system loss and the economic considerations for system expansion, based on experience with the Calcutta metropolitan utility
