Abstract
Apparatus and method are supplied for an electrical power substation used to interconnect an input three-phase power line to one or more poly-phase output distribution power lines. The teaching of the subject application shows that parasitic losses in prior art substation wiring that uses coaxial cables to conduct power into and out of the substation can be reduced by using an individual grounding rod for each outer conductor instead of following conventional practice and connecting all three conductors together at a common grounding rod. Moreover, if the three input coaxial cables to the distribution substation or the three output coaxial cables from the substation have the current in a center conductor precisely matched to the return current in the associated outer conductor, there will be neither an electric potential gradient nor a magnetic intensity outside of the transmission lines.
