Advantage of 3 phase over 1 phase : In single phase we have to use neutral wire 3 phase wiring is costless compared to 1 phase Higher phases: More than three phases are typically only useful when you need really clean electricity (lesser harmonic effects) or need to interact with very high voltage DC systems. Higher phases can be considered when you need to transfer a large amount of power, but there's the added consideration of integrating the higher number of phases with the three-phase standard for distribution.
