Automatic substations for industrial plants

Industrial enterprises have been the last to lake advantage of the developments in automatic station equipment. As an aid to the engineers responsible for these establishments, the author has described the principal types of electric-power transforming equipment to which automatic switching has been applied. The automatic control of synchronous condensers, synchronous motor-generators, synchronous converters, synchronous hydroelectric generators and feeders is treated in such a manner as to furnish industrial engineers with data upon which to base the designs of automatic stations for factories, mills, mines, shops and other kinds of industrial power supply.
