Abstract:
A lightning arrester is mounted on one end of a rigid insulator bar, the other end of which is mounted by a metal bracket to the grounded casing of an electrical distribution transformer. The ground terminal of the arrester is electrically connected with a terminal on the insulator bar intermediate the arrester mounting and the transformer mounting. A switch is remotely operable to establish electrical communication between the transformer casing and the intermediate terminal, and thus to the ground terminal of the lightning arrester.
