摘要:

All incoming materials used for insulating purposes have to comply with specifications or the special requirements of designers. This paper deals briefly with the details associated with the control of incoming materials, together with some special features associated with tests which have to be carried out in order that the performance of the materials under special conditions can be ascertained.To achieve this work special testing apparatus has been designed from time to time, and brief reference is made to some of the problems which have to be solved in order to ensure that the insulating materials selected will fulfil the performances required.Suggestions are also made dealing with the question of finding substitutes for insulating materials in short supply, and some of the new materials introduced for this purpose are mentioned.

摘要:

The objects of this paper are to review the principles and practice of the electrolysis of water and to discuss its interest to the electrical engineer.Following the chemical expression of the process, the various factors influencing the yields and power requirements are considered. In the theoretical treatment, the application of Faraday's laws is discussed, together with the question of current efficiency. The factors controlling the cell voltage, such as minimum-decomposition voltage, over-voltage, current density and resistance of electrolytes are studied, data being supplied as a guide to the general design requirements of this type of equipment. Methods and materials of construction are also discussed with some notes on the handling of the gases.Some modern types of apparatus are described and the performance of the equipment illustrated.The demand for the two gases is discussed and some of their uses are defined. Finally, the author suggests, on the basis of some of the figures included, that the large amounts of power concerned should be of the greatest interest to electrical engineers.
