TVA Wilson-Roane arrester

TVA Wilson-Roane arrester project. TVA added 500kv transmission line arresters on the Wilson – Roane 500kv line running from Wilson 500 to the Roane 500 station. TVA studies showed this line had multiple instances of lightning occurrences and it was chosen for their first 500kv transmission line arrester project. The project focused on the Cumberland Plateau area down to Roane County.
