Abstract
A method of maintaining a high voltage bushing can comprise inspecting a high voltage bushing connection, the high voltage bushing connection comprising a tubular lead, a lower stud connector, and the high voltage bushing. A method of maintaining a high voltage bushing can also comprise restoring the high voltage bushing connection, which can further comprise applying conductive material to at least one of a mating portion of a tubular lead and a mating portion of a high voltage bushing, machining an outside diameter of at least one of the mating portion or the tubular lead and the mating portion of the high voltage bushing to a predetermined outer diameter, and machining a mating portion of a lower stud connector to a predetermined inner diameter. A high voltage bushing connection can comprise a restored mating portion of a tubular connector and a restored lower stud connector.
