A multiconductor transmission line with distributed compensation Orton, Harry Ernest

Abstract

The thesis presents an analysis of the steady-state operation of a multiconductor power transmission line with distributed compensation. The analysis outlines two methods for deriving the voltage and current equations along the line starting from Maxwell's coefficients and the Telegraph equations. Correction factors due to an imperfect earth and conductor internal impedance are discussed. Also, by making the assumption that the system of conductors is completely transposed it is shown that considerable simplification of the equations is possible. Numerical results are given for a two and a four-conductor, single phase transmission line with earth return and for a three-phase system having four conductors per phase. The results show that successful operation of the system is prevented by electric field limitations at the surface of the conductors.
