Abstract: Voltage flicker is a power quality problem in power distribution circuits (10) which is caused by the operation of fluctuating loads (18) such as AC and DC electric arc furnaces, spot welders, starting of large ac motors, and the like. Converters (12) based on Voltage Source technology (VSC) connected in shunt close to the fluctuating load are found to have the capability of reducing the voltage flicker level. Flicker control systems (20) responsive to the active and reactive power components are used to exploit the capabilities of VSC in accordance with the invention. The flicker control systems (20) reduce the voltage flicker observed at the point of common coupling by adapting, e.g., H-infinity, Linear Quadratic Gaussian, Mininum Variance Control, and self-tuning design methods for flicker control in power systems (10) having fixed or self-tuning flicker controller parameters.

Abstract: The solid insulation transformer (10) has a rectangular core (50) covered with a compressible closed cell foam to eliminate stress during curing of the cast dielectric material (18) surrounding the core and during operation. Heat pipes (22) are placed between the inner coil and the core to extract heat before the temperature builds up. For safety and to eliminate the need for a separate enclosure, an outer multilayer casing (16) having an incorporated grounding conductive layer is provided to cover the sides of the cast body. The outer casing prevents explosion if dielectric breakdown and arcing occur, and reduces the danger of electric shock.

Abstract: An improved arc-resistant switchgear enclosure is disclosed. The disclosed arc-resistant switchgear enclosure provides a cost effective structure to collect and channel the pressure and hot gases through the switchgear enclosure. In preferred embodiments, an internal arc chamber (30') is formed by assembling modules and creating a void within the center of the switchgear enclosure. As multiple compartments or modules (10, 12', 14, 24) for a switchgear enclosure are connected, an arc chamber is created within the enclosure. Upon initiation of an arc fault within a particular compartment, a relief flap (40, 42) or cover (42) for that particular compartment opens to channel the pressure and the gases into the internal arc chamber or directly through the top of the enclosure (100). Pressures and gases are vented into the internal arc chamber and flow horizontally through the arc chamber until a path to the top of the switchgear enclosure is reached. These pressures and hot gases are then channeled upward and safely out of the switchgear enclosure. Also disclosed is a ventilation system for an arc-resistant switchgear enclosure that provides natural ventilation while preventing any arc gases from entering the lower, ventilated compartment or compartments. This ventilation system permits the proper venting of pressurized gases originating in the lower ventilated compartment or compartments.

Abstract: A method for manufacturing a laminate comprising at least two sheets of magnetic material is disclosed. The laminate (10) may be used to form a stacked transformer core. The method increases the productivity of the core-stacking process, decreases the core loss destruction factor, decreases total core loss, decreases acoustic noise generated by the electrical device employing the laminate, and does all of this in a manner which is commercially practical. The method comprises applying an adhesive (12), preferably a hot melt adhesive, in a pattern of thin beads onto one side of a first lamina or sheet of magnetic material, the pattern comprising a plurality of lines, the lines being substantially parallel to each other and substantially perpendicular to a direction of grain orientation or rolling direction of the lamina. A second lamina is then stacked onto the one side of the first lamina, and then a compressive force is applied to specified areas of the laminate. The spacing between the respective lines of adhesive is preferably 1-20 millimeters and, for an approximate diameter (D) of each bead, the spacing (S) between the beads of each line is preferably between D and 2D.
