Abstract :
A brief survey of significant developments in apparatus for the generation, transmission, and distribution of electric energy DEVELOPMENTS in electrical apparatus might be compared with the saying “From the acorn comes the mighty tree.” Likewise, the growth of the electrical industry can be compared with the growth of the tree into a forest. The acorn might develop into a great tree or be choked out by stronger trees or thoughts, but always the forest is increasing in coverage. When we examine the development of electrical apparatus we find a large number of thoughts that have not matured, whereas some one thought may have been the nucleus of a complete industry.
