ABSTRACT:
A plurality of threshold switches or comparators, at least two and preferably five to seven are provided to compare actual generator output voltage (u.sub.g) with respect to various threshold levels derived from battery voltage, and normal and abnormal and highly abnormal or excessive voltage conditions. Actual generator voltage is sensed by providing a separate set of rectifiers (14) connected to the generator (10) and providing output voltage signals representative only of the magnetism of the field--remanent or excited--and generator speed, independently of loading and battery voltage, to permit monitoring actual operation of the generator in relation to the connected network and battery. One (76) of the threshold switches or comparators is provided to inhibit energization of the field winding by the voltage regulator (20) if the voltage of the generator, as sensed, exceeds a predetermined level (eg. 18 V in a 12 V system), other threshhold switches providing malfunction indication upon concurrence of either excessive voltage, or undervoltage conditions at various test points within the generator-voltage regulator network system and combination.
