When the #electrical  #power  #system  is #unbalanced  the #voltages, #currents, and phase #impedances are in general unequal. Such a system can be solved by a #symmetrical  #per-phase #technique, known as the method of symmetrical #components. This method is also called a three-component method. The method of symmetrical components simplified the problems of the unbalanced three-phase system. It is used for any number of phases but is mainly used for the three-phase system.

The unbalanced three-phase system is solved regarding symmetrical components, and then it can be transferred back to the actual circuit. The balanced set of components can be given as a positive sequence component, negative sequence component, and zero phase sequence component.
