• High-phase-order systems for power transmission have been built and tested. Such transmission lines typically would use six phases or twelve phases in order to maintain both the cancellation of triplen harmonics and forgoing the need for a neutral wire for return. Higher-phase-order systems provide more efficiency and smoother power transfer. High-phase-order transmission lines allow transfer of slightly less than proportionately higher power through a given volume without the expense of a high-voltage direct current(HVDC) converter at each end of the line. However, with these benefits come issues of cost, equipment, and analysis. Higher phases require an increased number of buses and conductors, in addition to to more power transmission lines. These lines also need to be transposed significantly with one another-for example, a six phase power system would need to transpose the line a total of six times to maintain balance. Analyzing a system with higher phase is also much more complex than a three phase network; therefore, maintenance of a higher order system is more difficult to comprehend. Additionally, the increase in efficiency of one phase to three phase power is much more significant than the increase in efficiency of three phase to a higher phase; as a result, it is at three phase power that we find the optimal amount of power efficiency for cost. It is also important to note that there are little to no advantages for a four or five phase power system compared to a three phase system as these systems are unable to deliver constant power; therefore, only higher order n-phase systems that are multiples of three should be considered as being advantageous to the conventional three phase system.
