345-kV Line 60-Hz Ground Wire Losses

In considering the use of insulated and transposed ground wires for communications or other purposes, the magnitude of the ground wire losses were determined so that the losses could be properly evaluated as a cost or credit for this use when compared to the conventional construction of grounded steel ground wires. Three structure configurations and three different ground wire conductors were studied to determine the variation in the losses for different designs and conductors. The effect of changing the phase wire or ground wire configurations and changing the conductivity of the ground wires makes it necessary to analyze each combination of conductor configuration and ground wire conductivity.
