Abstract: The invention provides a high performance circuit breaker with an independent pole operation linkage and conical composite bushings. A mechanical linkage for independently opening and closing a plurality of associated switches is provided by the invention. The linkage comprises a plurality of connecting rods (32-34) that provide the initial driving force to open or close the switches, cranks (50) for opening and closing the contacts (12, 14, 15, 19) of respective switches, linking elements (36-39) which couple together the connecting rods (32-34) and the cranks (50), and a number of lever assemblies (40, 41) having a bearing ring (45, 46) interfaced thereto. The bearing rings (45, 46) provide a supportive interface between two linking elements (36-39) but permit the linking elements (36-39) to rotate independently from one another. The lever assemblies (40, 41) also provide an interface for the connecting rods (32-34) and linking elements (36-39). The present invention also includes a method of operation of the circuit breaker through the independent pole operation linkage.

Abstract: An electronic meter incorporates a TCP/IP protocol suite and an HTTP server (24) to provide two-way access to the meter incorporated into a gateway (20) serving multiple meters connected through a power line or wireless two-way network. The gateway (20) may incorporate an HTTP server (24) for accessing data from multiple meters (40) and for transmission of data to individual meters (40). Other aspects of the disclosed system include the use of a common gateway interface (26) for remote access to meter data and to set meter parameter using HTML forms in HTTP browsers; remote reading and setting of multiple meter parameters using a TCP/IP protocol suite; a TCP/IP protocol suite implemented in designated notes in a CEBus LAN (42) with remote access through TCP/IP (43) to routers and broutes and to individual meters on the LAN; and a SLIP-PPP (21) enabled gateway for remote TCP/IP access (22) through a serial interface to a single or multiple meter parameters.

Abstract: An adaptive distance relaying system (1) provides improved performance for parallel circuit distance protection. The system utilizes the parallel circuit's current, when available, in conjunction with measurements of voltage and current on the protected line to compensate for the zero sequence current mutual coupling effect. The sequence current ratio (zero or negative sequence) is used to avoid incorrect compensation for relays on the healthy circuit. If the parallel circuit current is not available and the line operating status is, the best zero sequence current compensation factors are selected accordingly as a next level adaptation. If both the parallel circuit current and line operating status are unavailable, a fallback scheme that offers better results than classical distance protection schemes is employed.

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.

Abstract: Twin metal billets (31) are fed to dual circumferential grooves (44) formed in a rotating wheel (43). The billets are advanced first to a edge-shaped gap which deforms the billets and are then advanced to a die (63). The die has a die opening with a circumferentially discontinuous, annular cross section. The metal from each billet merges in the die opening and exits therefrom in the form of a slit tube (34). The tube is then opened and flattened to form a flat strip (39) by advancing the slit tube over a forming member (38) having a progressively increasing width.

Selon une autre configuration, le premier processeur détermine et affiche les watts, les unités d'énergie de réaction visibles et le rythme auquel ces unités sont déterminées. L'affichage (30) peut fournir des informations sur la direction du flux d'énergie.

Abstract: A control for an inverter operable for converting direct voltage and current to alternating voltage and current. The inverter includes a plurality of electrical valves each operable to conduct current in a single direction upon the application of a positive voltage in the forward direction and the receipt of a trigger pulse. The control provides successive trigger pulses for commutating the current between successive valves at predetermined electrical firing angles and includes a voltage-time area calculating cir­cuit for calculating the maximum permissible firing angle which will permit successful commutation. An inverter commutation failure prevention circuit is coupled to the alternating current network for detecting abnormal voltage conditions and for producting a control signal functionally related to any deviation in the alternating voltage from the expected voltage condition. The control is responsive to the control signal for reducing the electrical angles of the trigger pulses provided to the valves.

Abstract: A method of manufacturing transformer windings embedded in casting resin is disclosed which utilizes an integrated winding mandrel for producing a non-standard oval shaped epoxy encapsulated low voltage coil for dry type distribution transformers. The method includes a process of winding a low voltage coil of alternate layers of copper conductor (24) and insulating tape (26), over a disposable mold formed by wrapping steel sheet material over inner mold support plates (14), the formed mold acting as both a winding mandrel and as an inner mold (20) for epoxy encapsulation. Both the inner and outer molds are made of low cost sheet metal utilizing a 'wrap and band' process. The complete winding and molding processes can all be conducted utilizing a conventional square mandrel shaft (12) on a standard coil winding machine (10).
