This voltage regulator is essentially a two-stage magnetic amplifier which derives its AC power from the generator output and supplies rectified power to the generator exciter field. The reactive load division circuitry provides balanced kVAR loading during parallel operation. In case of either a three-phase symmetrical line-to-line or line-to-earth fault, the regulator can usually supply sufficient excitation to enable the generator to supply current to operate protective devices. During an unbalanced fault condition, negative sequence sensing circuitry limits the highest phase voltage to specified limits. The regulator performs all of its functions with the AC generator and integral exciter as its only power supply.
