More than 3-phase system possible?

  1. Mar 7, 2010 #1
    hi all,

    Since there 1-phase,2-phase and 3-phase system is existing.Is it possible to have system more than 3-phases(theoretically and practically)?

    I think it is possible,is my opinion correct?

    both six-phase and twelve-phase systems are not unheard of, and are utilized in some very large DC converters. Six-phase converters may use a delta-wye transformer, which provides 30 degrees of phase displacement. Zig-zag transformers provide 90 degrees phase displacment.
