The Application of D-C. Generators to Exciter Service

In the design of direct-current generators for exciter work, there are a number of problems peculiar to this kind of service, the variety and importance of which have been considerably increased by the use of automatic voltage regulators. It is the purpose of this paper chiefly to discuss the relation of exciter design to some of these problems, such as voltage range, responsiveness, stability, and type of drive, with especial reference to the requirements of automatic voltage regulators.
