.~.~ Substitute or auxiliary starting source of excitation
DEFINITION
Classification: 322/60
(under subclass 59) Subject matter wherein a substitute or auxiliary source of voltage is provided to energize the excitation circuit of the generator during the starting period so that the generator can "build up" its output voltage means being provided for discontinuing the supply to the excitation circuit from the substitute or auxiliary source when the generator has attained a predetermined output voltage.
SEE OR SEARCH THIS CLASS, SUBCLASS:
10, for generator systems within the class definition where means are provided for physical starting and putting the generator into service.
28, for generator systems within the class definition having automatic control means responsive to the generator output voltage for discontinuing the supply of the voltage to the excitation circuit when the generator output voltage has attained a predetermined value.
86, for generator systems under subclass 59 having the generator excitation circuit supplied from two or more sources of electric energy, both sources usually being used during the normal operation of the generator.
