  • Publication number: 20200182921
    Abstract: Example embodiments of the invention include a powdered core bead body configured to become an inductive impedance to current signals in a power wire with high frequencies. The signals are detectable by a high frequency voltage sensor, which is configured to output an arc fault tripping indication to an arc fault tripping circuit. The bead body includes a magnetic flux-density sensing device embedded in an air cavity of the bead body, having a magnetic field sensing surface oriented substantially perpendicular to the circumferential periphery of the bead body. The bead body is configured to provide measurable magnetic flux through the magnetic flux-density sensing device, for currents in the power wire having low frequencies. The measurable magnetic flux is detectable by a low frequency magnetic flux-density sensing device, to output a low frequency current measurement for power metering devices or to determine power consumption within a protected branch.

  • Patent number: 8711549
    Abstract: A busway having multiple busbar conductors and pads composed of a thermally conductive, insulating material (TCIM) sandwiched in between each of the conductors and between the outermost conductors and the inside of the busway housing. The busway preferably includes three sets of TCIM pads, one set in the center of the busway, and a set at either end of the busway where a joint pack is installed to join multiple sections of busway sections together. The insulating material on the conductors has a cutout to expose the bare metal of the conductors, and a TCIM pad is placed directly on the exposed metal through the cutout, to form a thermal conduit between the busbar conductors to the metal housing of the busway, thereby reducing the temperatures of the busbar conductors and the joint pack during normal operation in which hundreds or thousands of amps of current are carried through the busway sections.

  • Patent number: 8619411
    Abstract: Electrical switchgear comprising electrical switching equipment for a multi-phase electrical power distribution system, a supporting structure for a bus assembly for supplying electrical current to the switching equipment, and a plurality of spaced buses mounted on the supporting structure each for connecting the switching equipment to respective phases of the multi-phase electrical power distribution system. Each bus comprises a plurality of substantially co-planar, spaced, elongated flat conductors arranged with at least one longitudinal edge surface of each conductor in that bus opposed to and spaced from a longitudinal edge surface of another conductor in that same bus, and a connector at each end of said conductors for connecting the plurality of flat conductors in each bus to each other.

  • Patent number: 8378219
    Abstract: A bus assembly and bus assembly connector include one or more insulated members that have axial sleeves that fit within one another during assembly to form a nesting arrangement. The nesting arrangement of the axial sleeves allow reduction of the overall size of the bus assembly connector while satisfying power rating standards and dielectric clearances as well as allowing bolting of the bus assembly to thereby clamp and secure the bus assembly. The axial sleeves can be distinctively designed such that the phase members must be assembled in a predetermined order, with no components being omitted, to form the bus assembly connector or clamp the bus assembly.

  • Patent number: 7819681
    Abstract: A busway joint pack includes a pair of opposing phase connector plates, a first insulating sheet, a second insulating sheet, a first side panel, and a second side panel. The busway joint pack passively transfers thermal energy generated in its core to an exterior housing such that the thermal energy is dissipated or transferred to the surrounding environment, which reduces the internal temperature of the joint pack. The first and the second insulating sheets are positioned and selected with a particular thermal resistance and dimensions such that a portion of the thermal energy generated in the core of the busway joint pack is transferred from the pair of opposing phase connector plates to the external housing.
