It is well known that 3 phase unbalanced systems can be resolved into three balanced systems, whilst this is true the underlying reasons for the decomposition is almost non-existent in the literature. The concept was originated by C L Fortescue as a consequence of his work on rotating machines under unbalanced conditions. He observed that the solutions always reduce to two or more symmetrical sets. From these observations he successfully formulated symmetrical components but he did not identify the theoretical fundamental reasons why such combinations occur.


The aim of this presentation is to show how vectors with complex coefficients can represent three phase sets and resolve them into balanced systems. Fortescue's method is revisited to indicate how the addition and subtraction of symmetrical sets reveals the spectrum of the unbalanced set.
