  • AC Power Distribution System with Transient Suppression and Harmonic Attenuation
    Publication number: 20100045109
    Abstract: An AC power distribution unit for coupling AC power having a fundamental frequency to a plurality of electrical loads has an enclosure. A power input feed is retained by the enclosure for coupling to a source of the AC power. A plurality of power output feeds is retained by the enclosure for coupling to the plurality of electrical loads. A harmonic mitigation module is retained in the enclosure and is connected in series between the power input feed and the plurality of power output feeds. The harmonic mitigation module bilaterally reduces harmonic current distortion above a predetermined frequency between the power input feed and the plurality of power output feeds.
