The discussion focuses on the differences between 3-phase and 6-phase transmission systems. A 6-phase power line configuration significantly reduces the electric and magnetic field intensity associated with AC power transmission. Research indicates that existing double 3-phase transmission lines can be converted to 6-phase systems, utilizing an open-wire configuration that is compatible with existing power line right-of-ways. This conversion offers a practical solution for enhancing transmission efficiency and safety.
