Web2. SYMMETRICAL COMPONENTS The method of symmetrical components allows to solve unbalanced systems using balanced techniques. This method was introduced by C.L. Fortescue in 1918. The theory of Fortescue was proposed in which, an unbalanced system of "n" related phasors can be resolved into "n" systems of balanced phasors called … WebMar 27, 2013 · The a.c. system is broken down into it's symmetrical components as shown above. Each symmetrical system is then individually solved and the final solution obtained by superposition of these (as shown above). For the more common fault conditions, once the sequence networks are known we can jump directly to the fault current.
