Abstract

Utility systems must nowadays handle a variety of a large 1-phase industrial loads which ean have a serious effect on the symmetry of a 3-phase supply system. This paper introduces a method by which 1-phase loads can be reflected as symmetrical three phase in order to avoid unbalancing the feeding 3-phase supply. For this purpose, a statie wauless device is presented which proves to be practicable for any single-phrase load. Additionally, the device is more important when the power -factor of the 1-phase load is equal or near unity.
