This paper presents a complete analysis for the unbalance problem in O.H.T.L. which arises due to T.L untransposition. Derivations for the electromagnetic unbalance factors by the application of symmetrical component analysis are introduced. The main factors affecting electro-magnetic unbalance factors are discussed with special regard to double circuit T.L. Numerical application is made to clarify the degree of effectiveness for each factor.
