Abstract

Untransposition in O.H.T.L. creates the unequiality of T.L. phase impedances. Several problems are srised due to the out -of- balance of the phase impedances. The main of which is that it affects on the system performance. For the seek of system analysis with untransposed T.L., the modeling of system element in matrix form is given and the modeling of the power system as a whole is also cleared. The methods for the reduction of the out-of-balance are discussed and the flow-chart for the problem analysis is given. It could be noticed that transposition is the best method for the out-of-balance reduction, but it reduces the reliability of the system.
