ABSTRACT:
An auxiliary stranded copper conductor carries the fault currents generated by a diode failure about the periphery of a brushless exciter diode wheel. The auxiliary conductor is constructed with a lower high-frequency impedance than the adjacent diode wheel, so that AC fault currents in particular are diverted to the auxiliary conductor. The auxiliary conductor carries the fault currents to equalize both AC and DC fault currents among the fuse-legs of the same phase. In a preferred embodiment, the auxiliary conductor is circular and is mounted between all of the diode fuse bases at one end of the diode wheel and the diode wheel itself.
