摘要:

DC railway systems have now crystallised into the three major categories of 750V, 1500V and 3000V, the latter being applied to main-line systems and the first two mainly to urban masstransit or light-rail systems. This article reviews the significance of choice of transformer commutating reactance and highlights its importance in the design of DC substation convertors

摘要:

The ability to assess the integrity of high-voltage insulation in installed electrical plant is important in determining future serviceability. Several techniques and purpose-built instruments which have been developed at CERL are usedto test a range of power-station and substation plant within the CEGB

摘要:

Increasing demand for electrical power in centres of large conurbations has led to the development of compact gasinsulated substations. For these it is not possible to follow established practice of fitting co-ordination gaps, and therefore surge arresters have to be used to limit overvoltages

摘要:

The prospect of a major programme of switchgear replacement in the UK has led to a number of innovative proposals in the fields of plant, protection and network design. In addition to lowering the cost of systems, the new techniques enable the planned reliability of supply to be more closely matched to customers' requirements

摘要:

This article analyses the electrical principles involved in lowvoltage (600/1000 V) power cables, many of which are applicable to power cables of higher voltages as well as wiring cables. Following a look at theoretical aspects, the article focuses on practical cable selection, mainly based on the author's experience in the Gulf countries of the Middle East
