In one embodiment, an automatic voltage regulator includes a detection instruction unit configured to monitor a generator output voltage, and output an instruction signal when the output voltage of the generatordeviates from a predetermined range, the instruction signal being a signal of instructing detection of a specifying parameters generated in a generator field circuit of a generator excitation system; a field-parameter detection unit configured to detect the specifying parameters following to the instruction signal; and a comparison calculator configured to calculate a comparison value between the specifying parameters and a predetermined allowable upper-limit voltage-value of each component constituting the generator excitation system.

In one embodiment, a generator includes an alternating current exciter to output first, second and third alternating currents respectively having first, second and third phases, and a rotary rectifier to convert the first, second and third alternating currents into first, second and third direct currents, respectively. The generator further includes a rotating shaft on which the exciter and the rectifier are mounted, and plural conductors mounted on the shaft, and including one or more first conductors, one or more second conductors and one or more third conductors to respectively supply the first, second and third alternating currents from the exciter to the rectifier. The plural conductors include one or more conductor groups in each of which two or more conductors are collectively arranged, and each of the conductor groups includes the two or more conductors arranged to cancel a magnetic field around each conductor in the same group.
