ABSTRACT:
A six-phase power line configuration reduces the measured intensity of electric and magnetic fields that are associated with transmitting AC electric power. An open-wire configuration is taught that is compatible with transmission on power line right-of-ways, and that can be made by converting existing three-phase dual circuit power lines.
