An electrical repair plug device replaces an original plug device that has been severed from the electrical cord. A housing comprises a base enclosure and a top enclosure that snap together to secure the housing to the electrical power cord. A strainer comprises a strain relief on one end coupled to the electrical power cord and the housing. The strain relief provides support for conduction wires exposed from a skin of the electrical power cord by decoupling external force on the electrical power cord from the conduction wires. The housing includes individual channels for each of the exposed conduction wires, each individual channel insulated from each other and including a plurality of teeth to bite the exposed conduction wires.

A turbogenerator includes a stator core defining a first end and a second end, a plurality of stator bars disposed within the stator core, each stator bar including a coolant flow path, and a parallel ring having a first segment and a second segment separate from the first segment. The parallel ring is coupled to the first end of the stator core and is arranged to electrically connect the plurality of stator bars and to fluidly connect the coolant flow paths of the plurality of stator bars. A tang includes a main chamber, a first coolant opening, a second coolant opening, and a distribution channel that fluidly interconnects the main chamber, the first coolant opening, and the second coolant opening. A first lead tube has a first lead end connected to the first coolant opening and a second lead end connected to the first segment, and a second lead tube separate from the first lead tube has a first lead end connected to the second coolant opening and a second lead end connected to the second segment. The plurality of stator bars, the parallel ring, the tang, the first lead tube, and the second lead tube cooperate to define a portion of a circuit and a portion of a cooling path.

The disclosure relates to a slip ring assembly, which has a slip ring body and at least one slip ring arranged on the slip ring body and a contact module having contact elements. The contact elements contact a slideway of the slip ring. A cleaning device is provided for cleaning the slideway. According to the disclosure, the cleaning device has a cleaning brush having a brush filling contacting the slideway.

A contact spring holding jig for grease application includes a spring placement portion on which a connector terminal contact spring is to be placed, and a spring position restricting wall. The connector terminal contact spring includes a plurality of spring pieces and a connecting portion positioning at an end portion of the connector terminal contact spring. The plurality of spring pieces include a gap with adjacent spring pieces are connected to be arranged side by side by the connecting portion. The connector terminal contact spring is placed with the connecting portion facing downward, on the spring placement portion.

A self-lubricating connector with a housing having a contact receiving cavity with a contact provided therein. A lubricating device is positioned in the housing proximate the contact. The lubricating device extends into the contact receiving cavity and has lubricant provided therein. The lubricant from the lubricating device is deposited or on the outside surface of the contact as the contact is moved between the first position and the second position, reducing wear on the contacts as the contacts are moved between the first position and the second position.

An electrical power system including an electrical power connector, a contact configured to electrically connect a power supply to a load, a first sensor configured to sense a first characteristic of the electrical power connector, a second sensor configured to sense a second characteristic of the electrical power connector, and an electronic controller. The electronic controller configured to receive a first signal indicative of the first characteristic, receive a second signal indicative of the second characteristic, compare the first signal to a first threshold, compare the second signal to a second threshold, and dynamically adjust at least one selected from a group consisting of the first threshold and the second threshold. Wherein the dynamic adjustment is based on at least one selected from a group consisting of a measured or calculated parameter, an installation condition, an operational limit, a known operational behavior, and parameter threshold information.

A probe for characteristic inspection of a connector includes a plunger, a coaxial cable, a flange, and a housing having an end portion on one side including an increased diameter portion. A recessed portion which receives the increased diameter portion is in an upper surface of the flange. The increased diameter portion has side walls in contact with or facing respective inner side surfaces of the flange partly, with the inner side surfaces forming the recessed portion, and a bottom wall in contact with an upper recessed surface of the flange that forms the recessed portion. The increased diameter portion has connection surfaces connecting the bottom and side walls and inclined inward from one of the side walls toward the bottom wall. Alternatively, the inner side surfaces each have a first surface inclined downward, and a vertical surface extending downward from the first surface to the upper recessed surface.

A power distribution monitoring system is provided that can include a number of features. The system can include a plurality of power line sensing devices configured to attach to individual conductors on a power grid distribution network. In some embodiments, the power line sensors can include a split-core transformer. In some embodiments, a power line sensing device is disposed on each conductor of a three-phase network. The sensing devices can be configured to measure and monitor, among other things, current and electric-field on the conductors. Methods of installing, sealing, and protecting the split-core transformers of the power line sensors are also discussed.

The disclosure relates to a shielded Y-shaped splice connector having a housing that includes a lower body, an upper cover, and three openings arranged to receive three cable fixing devices on the housing. The periphery of the lower body and the periphery of the upper cover are each formed of a flat surface arranged to form the contact surface of the lower body and the upper cover when the housing is assembled.
