Abstract: An elbow terminator has a socket in which an electrical probe is disposed. The terminator is insertable onto an electrical bushing such that a tongue of the bushing is received in the socket of the terminator, and the probe of the terminator is electrically coupled to a contact sleeve disposed within the tongue. A latching mechanism produces positive latching between the tongue and socket when the tongue has been inserted to a predescribed depth within the socket. In order to enable an operator to visually observe that the tongue has been inserted to the prescribed depth, the bushing carries a color band which becomes completely disposed (invisible) in the socket when positive latching occurs. Alternatively, the bushing can be provided with gauge tabs which become aligned with a witness line formed on the terminator when positive latching occurs.

Abstract: An improved method of manufacturing, modifying and repairing a switchgear is disclosed that includes a busbar system and active switching elements that can be assembled from modular parts.

Abstract: Improved switchgear is disclosed that includes a bus bar system that can be assembled from modular parts. The bus bar system includes modules, such as high-voltage cables, connectors coupled to the cables and a third cable-less bus bar that is assembled using mechanical and/or push-on connections. By using these types of bus bars, various configurations, orientations of phase planes, and sizes of bus bar systems may be assembled. The connectors and cable-less bus bar may include either push-on connection points, mechanical connections points or a combination of both. The bus bars may themselves include insulation and semiconductive shields. The improved switchgear may also include solid insulation, such as EPDM rubber, to insulate the bus bar system from the exterior surfaces of the switchgear.

Abstract: A control system and method for a motorized high voltage loadbreak switch.

Abstract: Insulated vacuum switchgear and active switchgear elements therefor are provided with a rigid support structure mechanically isolating a vacuum insulator from axial loads in use without reinforcing or insulating encapsulations. At least one of the elastomeric insulating housing and the support structure directly contacts an outer surface of the insulator. Systems and methods for assembling the switchgear are also provided.

Abstract: A latching mechanism for joining separable insulated connectors employs a plurality of finger contacts to create an interference fit with an electrode probe of an elbow connector. The electrode probe enters a cylindrical grouping of the plurality of finger contacts and a projection causes an interference fit between the finger contacts and the electrode probe. The finger contacts latch the connectors together and require a removal force greater than the latching force required to latch the connectors. The latching mechanism provides a multi-point current path between an elbow connector and a power transmission or distribution apparatus and provides operator feedback to indicate the latching of the mechanism.

Abstract: A housing for a current limiting fuse that includes a metal fuse element and a non-conductive filler material. The fuse element is configured to melt to create an open circuit when an applied current exceeds a threshold amount. The housing includes first and second cylindrical members. The first cylindrical member has an open end portion and the second cylindrical member has an integrally formed closed end portion and an open end portion configured to be attached to the open end portion of the first cylindrical member to close the housing. The housing also includes a fastening member configured to prevent the open end portion of the first cylindrical member from separating from the open end portion of the second cylindrical member when the fuse element melts.

Abstract: A device includes a first conductive member configured to be electrically coupled to a first component and a second conductive member configured to be electrically coupled to a second component. The second conductive member is separated from the first conductive member by a gap. A conductive connecting member is moveable to make an electrical connection between the first and second conductive members across the gap. A housing receives the first conductive member, the second conductive member, and the connecting member. The housing includes an insulating layer and a conductive layer. The movement of the connecting member to make the electrical connection is visible through at least a portion of the insulating layer and the conductive layer.
