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.
Claims5
In association with a distribution transformer having a grounded metallic casing and a high voltage terminal, and a lightning arrester having a ground connection and high voltage terminal connected to the high voltage terminal of said transformer, safety apparatus comprising:
- an insulating support member extending from said transformer casing, said arrester being mounted on said support member in insulating spaced relation to said transformer casing;
- and
- remotely actuated means for making electrical connection between said transformer casing and said ground connection of said arrester.
