.~ Automatic generator control and/or with time-delay means {5}
147
.~.~ Speed or frequency of generator or its drive means
DEFINITION
Classification: 318/147
(under subclass 141) Subject matter in which means are provided for controlling the generator in response to the speed of the generator or the frequency of the voltage or current generated thereby, or in response to the speed of the generator driving means.
SEE OR SEARCH THIS CLASS, SUBCLASS:
145, for motor control systems which are responsive to the terminal voltage or the c.e.m.f. of the motor which may correspond with the armature circuit voltage of the generator and hence to the speed of the generator.

322, Electricity: Single Generator Systems,
29+, for automatic generator control in response to the speed or frequency of the generator.
