Power-line carrier Application

RAPID LOAD GROWTH during the past few years has dictated the installation of new high-voltage transmission lines through densely populated urban areas served by The Detroit Edison Company. Overhead construction, being much cheaper, is preferred; however, right-of-ways difficulties or local ordinances may require underground construction or at least the use of a section of underground cable in a high-voltage line. A composite line of this description was selected to supply new Northwest Station and, also, serve as part of a system tie between existing Northeast and Evergreen Stations.
