摘要： An interface layer and method is provided that permits applications (10), without modification, to operate with any type of meter (30). The interface (20) comprises an abstraction layer and library or repository of descriptions specific to each meter type. The abstraction layer provides the capability to communicate with any meter (30) through a variety of applications (10). Upon receiving an application request, the abstraction layer retrieves the description for the particular meter type from the repository and processes the request. In this manner, only one data representation is needed for applications to communicate with a wide variety of meters (30).

摘要： A cryostat for superconducting transformers is provided which includes an electrically non-conducting load bearing thermal insulation that is adapted for use with a superconducting transformer. The cryostat (10) also prevents the formation of closed loop stray currents on its outer case. The cryostat contains the winding sets (30) and other related electrical equipment of 3-phase electrical transformer as tap changer (28) and electrical leads (29). The cryostat with lid (14) generally comprises a heat insulated cryogenic tank having an outer wall (18), electrically non-conducting liner (22), and load bearing thermal insulation layer (20) disposed therebetween. The tank holds liquid or gaseous cryogenic coolant (34) into which transformer components are immersed, thereby reducing electrical resistance losses or wire losses and magnetic hysteresis losses or core losses. A plurality of passages allow the passage of the limbs or legs (36) from iron core (32) of the transformer through the cryogenic tank.

摘要： A steel plate (130) of area greater than the area of the output of a nozzle (95) in a puffer gas interrupter (15-17) is fixed to but is spaced from the downstream end of the nozzle (95) and causes turbulence in the hot interrupter gases flowing through the nozzle (95) to improve mixing with cooler downstream gas.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
