ABSTRACT:
To prevent over-excitation upon high-speed operation of a compound wound alternator, the shunt field, connected in standard manner to a voltage regulator, has an additional shunt field winding placed on the core, the additional shunt field winding being controlled from the output of the alternator and generating a magnetic field counter the field due to the compound winding if an auxiliary counter field voltage regulator senses that the output voltage of the alternator rises above a predetermined value.
