Selection, design, and operation of power transformers

THE American Gas and Electric Company system is an outgrowth of many originally isolated systems of diverse origin and characteristics. It serves 1,100,000 customers in more than 2,000 communities. Well integrated and thoroughly interconnected with 16 neighboring systems at 36 different points, its transmission extends over an area with a population of approximately 4,000,000 people in seven states. Power is served to some of the most highly industrialized portions of the nation, albeit about one-third of its customers live in rural areas.
