ELECTRICAL GROUND APPARATUS FOR TESTING THE QUALITY OF CONDUCTORS

摘要

Apparatus for testing the quality of an electrical ground conductor by completing a high-current low-voltage series circuit between the electrical ground conductor being tested and ground, and observing indicating means disposed in series therewith. Circuitry is provided for inducing this high-current low-voltage into the series circuit only when a normally open manually operable switch means is closed and only then, if there is continuity of the electrical ground conductor with ground.
