ABSTRACT:
An easily removable high voltage ground stud insulating system allows ready access to the ground stud bolt having one end directly attached to a switchgear terminal bus, with the other end adapted to receive a temporary ground connector. A two-part insulative enclosure consisting of a first thermoplastic insulative cylinder is arranged over that part of the ground stud that is adapted for connection with the ground connector while a second insulative cylinder is arranged over the other end. The insulating properties of the thermoplastic material virtually eliminate arcing between the ground stud and the surrounding atmosphere when the switchgear is energized with high voltage. The insulating system is adapted for connection with the ground stud by means of a pair of threaded washers that serve to attach the insulative cylinders on both sides of the ground connector.
