Abstract

In this article we are referring to distribution of electric energy through three-phase cable conductors on the basis of worked out mathematical model. This model includes availability of inductive and capacity couplings between cable conductors. Calculations made on the basis of this model show that in case of the extension of cable power lines by several kilometers, cross-couplings between conductors result to quality deviation of electric energy due to the occurrence of asymmetry of voltage system on range and phase.
