    The paper begins by summarising the way in which the design of high-voltage (above 1 kV) switchgear has been affected by changes in the constitution of the manufacturing industry, both nationally and internationally, by advances in the knowledge and theory of arcs and circuit breaker operation, and by changing tendencies in service conditions that influence specification, rating and testing requir...

    The review links the development of British submarine telephony during the last 25 years with the development and production of the active elements, thermionic valves and silicon planar transistors, in the submerged repeater amplifiers. These devices have played a major role in determining the performance, capacity and reliability of all submarine transmission systems. While concentrating on the w... View full abstract»

    This review outlines the history of noise measurement in the `pre-electronic¿ era, and then goes on to describe current practice. The first five Sections are devoted to the `engineering¿ aspects of the subject, i.e. the methods used to make physical measurements of noise parameters viewed as a series of pressure fluctuations in the air. As well as measurements at normal levels in the normal audi... View full abstract»

    The paper reviews the trends in the development of hydroelectric generating equipment for conventional and pumped-storage plants over the past 25 years. The growth in unit capacities, sizes and operating head ranges is outlined for various types of turbines. The features in generator design required to meet the growth of unit capacities are discussed for low-speed and high-speed machines. This rev... View full abstract»

    Modern knowledge of the amplitudes and waveshapes of lightning currents enables a method of determining the electrical effects of a direct lightning stroke to be established. It has been shown that this entails an initial current discharge through the body, followed by an external flashover. The amplitude and waveshape of the current flowing through a body can thus be determined. The phenomenon of... View full abstract»
