Complex electrically operated ground and test device using vacuum circuit interrupters and methods of operating the same

摘要

A grounding and test device includes a chassis configured to be removably installed in a drawout switchgear compartment (e.g., a breaker compartment) having a load conductor and a line conductor therein. The device also includes an interconnection bus supported by the chassis and a ground conductor supported by the chassis. The device further includes a first vacuum circuit interrupter supported by the chassis and configured to selectively couple and decouple the interconnection bus and the line conductor, a second vacuum circuit interrupter supported by the chassis and configured to selectively couple and decouple the interconnection bus and the load conductor and a third vacuum circuit interrupter supported by the chassis and configured to selectively couple and decouple the interconnection bus and the ground conductor.
