Abstract
IT is at first sight surprising that anyone should write a treatise on power-frequency electrical engineering since comparatively little of a novel nature has been added to either theory or practice of electrical machines in the past twenty years. Within the last few years, however, the electricity supply systems of many countries have been integrated into a well-defined unit in which all the generating stations operate in conjunction with one another on a large, common high-voltage network. This practice has resulted in the development of much larger generators, transformers and other equipment than were used when individual power authorities operated comparatively small local electrical systems. Many problems involving stability of operation, short-circuit stresses, surge voltages and load control have thereby become accentuated. Great numbers of people have also become intimately interested in large-scale electricity supply ; in Great Britain, for example, the British electricity supply industry employs about 150,000 people, most of whom should aspire to attain a good level of technical knowledge regarding the equipment used in providing the public with electrical energy.
