  • Obeserve the Zero Sequence components magnitudes when 3-phase nature is unbalanced with sum = 0.
  • Observe the zero, +ve, -ve Sequence components and their magnitudes when 3-phase nature is balanced.

Here the letter X represents any 3-phase quantity. Be it 3-ph currents, 3-ph voltages, 3-ph fluxes or etc

The original paper on the method of symmetrical components, titled “Method of Symmetrical Coordinates Applied to the Solution of Polyphase Networks,” was presented by Charles LeGeyt Fortescue at the 34th Annual Convention of the American Institute of Electrical Engineers in Atlantic City, NJ, on June 28, 1918. DOI: 10.1109/T-AIEE.1918.4765570
