DEFINITION

Classification: 322/17

(under the class definition) Subject matter wherein the generator or driving means are provided with automatic means so that either is controlled in response to predetermined conditions. Sensing means are provided which are responsive to the condition or conditions to effectuate the control.

SEE OR SEARCH THIS CLASS, SUBCLASS:

11, for automatic starting and/or stopping of the generator in response to predetermined conditions.

38, for miscellaneous systems within the class definition having driving means control.

44, for miscellaneous systems within the class definition having generator control.

SEE OR SEARCH CLASS 318, Electricity: Motive Power Systems,

141+, for generator fed motor systems having automatic generator control.

320, Electricity: Battery or Capacitor Charging or Discharging, appropriate subclass for a battery or capacitor charging or discharging system with automatic regulation.

323, Electricity: Power Supply or Regulation Systems, for miscellaneous voltage and phase control systems.

330, Amplifiers, appropriate subclasses, for amplifier systems, generally, including those which may be used in the automatic control of generators, particularly

58, in the amplifier systems of which the active element is a rotating dynamoelectric machine.
