Abstract:

A grounding system for grounding the neutral conductor of an electrical distribution system. A point of reference potential with respect to true earth ground potential is provided. An amplifier has a first input connected to the reference potential and a second input connected to the grounded neutral conductor. The amplifier provides an output signal indicative of the difference between the undesired stray voltage on the grounded neutral conductor and the reference potential. The amplifier develops the output signal across the secondary winding of an output transformer. One terminal of the output transformer is connected to the grounded neutral conductor of the distribution system. The other output terminal of the transformer is connected to true earth ground by way of an auxiliary ground path having a finite resistance. The grounding system thus reduces the magnitude of the neutral-to-earth voltage, including transient variations thereof, to a value approaching, or more nearly equal to, true earth ground potential.

Abstract:

The wedge connector includes a longitudinally extending spring member which is generally C-shaped in cross section and which is tapered along its longitudinal length. A correspondingly tapered and longitudinally extending wedge member is insertable into the spring member and includes a pair of arcuately shaped retaining extensions along one side of the wedge member. The wedge member includes a plurality of longitudinally extending threaded bore holes for receiving a bolt which extends perpendicularly through the spring member wall. Accordingly, the wedge connector can be bolt-assembled or impact-tool-assembled by respectively reversing the position of the wedge member.
