1. A system comprising at least two adjacent power transmission tower structures including lower power conductors and upper power conductors, the system comprising at least one existing overhead ground wire and an embedded ground wire or wires, wherein the embedded ground wire is connected between the two adjacent power transmission tower structures at or in a vicinity of a vertical axis of each of the power transmission tower structures in a position at or above attachment points of the lower power conductors and below the upper conductors, wherein the position of the embedded ground wire or wires optimizes coupling factors to all said power conductors for improved back flashover lightning performance.
