DEFINITION

Classification: 322/84

(under subclass 83) Subject matter wherein the short circuit of the control resistor is intermittently completed and opened.

(1) Note. In the systems in this subclass the effective value of the resistor is determined by the periodicity of the circuit making and breaking and the ratio of the time the shunting circuit is open to the time it is closed.

SEE OR SEARCH THIS CLASS, SUBCLASS:

70, for generator control by continuous making and breaking of the excitation. In subclass 70 the excitation circuit is periodically opened and closed.
