摘要：This paper presents the issues of electromagnetic interactions in a four-circuit and dual-voltage power line.Such solutions are increasingly used in practice due to difficulties in land acquisition for the construction of new power lines.Lines of this type,however,have some disadvantages, incl.the electromagnetic interactions between the circuits and voltages induced as their consequence.These issues are considered in relation to an existing four-circuit,110 kV and 15 kV line.Results of the studies of the interaction effects in a real system,and an analysis of selected ways to reduce the voltage induced in 15 kV line circuits are presented.
