A propos du livre

Présentation de l'éditeur

At present the cost of electric generators is high, partly on account of the fact that only a small temperature rise is permissible. There seems to be little reason to doubt that with the advance of technical applications and artificial local cooling the cost of large generators may be reduced to one-half, or one-third of the present cost per kilowatt. Indirectly the question of efficiency is raised through the use of cooling devices, and this is discussed. Very little appears to have been written on the subject of ventilation, but where the author is indebted to other writers it is duly acknowledged in the text. Methods of measuring the ventilating effect of armatures are indicated in the chapter on Ventilating Action of A rmatures. They may be recommended as rapid workshop tests, and although exception may be taken to them on various grounds they are preferable to the present state of matters, viz. no tests at all. The author considers the present is a very opportune time to draw attention to this question. It is not generally realized, for instance, that the so-called Output Coefficients are merely functions of ventilation, and that it is not correct in discussing them to ignore ventilation altogether.
