Abstrakt EN: This paper deals with analyses of the mutual influence between the circuits with different voltages located on the same transmission tower. This mutual influence of parallel circuits is caused by mutual inductive and capacitive couplings between the conductors. The effect of mutual couplings leads to a phase current asymmetry during an operating state. In this paper there is presented a method which can evaluate the origin of the phase current asymmetry. The multi-circuit line has been modelled with the help of two-ports, which are coupled with inductive and capacitive couplings. The phase configuration optimization with respect to the reduction of phase current asymmetry is also presented in this paper.
