Optimization of Cable Layout With Consideration of Environmental Impact

This article discusses the possibilities of optimizing layout underground power cable lines considering environmental requirements. It presents the basic mechanisms of the occurrence of the physical phenomenon of a magnetic field. The permissible levels of magnetic field emissions around the world are discussed. Case studies analyze the impact of cable laying conditions on the magnitude of the magnetic field. A discussion is offered on the possibility of a reasonable reduction of the negative environmental impact of underground cable lines, namely, through the proper selection of the arrangement of the phases and distances between the cables.
