Abstract

Abstract A device is described which is used to ground power distribution subterranean cables. A grounding module may be positioned over a connector to the power cables. A remote trigger then fires a probe through an insulating cap on the connector to make a ground circuit from the cable through the connector and probe to a grounding clamp.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 288 words
A remote grounding device for subterranean power cable of an insulated conducting cable which comprises a grounding module and a grounding mechanism, said grounding module is an assembly of a power buss, an insulation sheath, a reducing tap plug and an insulating receptacle cap, said power buss being intimately connected to the conducting cable by a means of an attachment, said reducing tap plug fitting concentrically over said power buss and having a tubular probe path void contiguous and in-line to said power buss and a lip around the outer periphery of said reducing tap plug, said insulating receptacle cap covering the tubular void, said insulating sheath covering and holding said reducing tap plug and power cable by a multiplicity of locking means, and a grounding mechanism assembly of a frame, a probe, a power drive means, a grounding means, a handle means, said frame having a groove and being open on one side, said probe being geometrically located on said frame at a central point, so that when said groove engages said lip said probe is directly in line with said probe path void, said probe being of smaller diameter than said probe path void, said power drive means coupled to said probe on said frame, grounding means attached to said probe at one extremity, and said handle means attached to said frame, so that the handle directs the frame onto the reducing tap plug by the lip and groove so the probe is above the center of the probe path void, when the power drive means is excited and the other extremity of the grounding means is grounded, the probe penetrates the insulating receptacle cap and contacts the power buss, resulting in a grounded power cable.
