摘要： Twin metal billets are fed to dual circumferential grooves formed in a rotating wheel. The billets are advanced first to a wedge-shaped gap which deforms the billets and are then advanced to a die. 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. The tube is then opened and flattened to form a flat strip by advancing the slit tube over a forming member having a progressively increasing width.

摘要： A method for generating a computer model for use in system component design as well as overall system evaluation is disclosed. The method includes the steps of generating an equation model of the system component, modifying the equation model by integrating according to the trapezoidal rule, wherein an integrated model is formed having a plurality of parameter values. Certain of such parameter values define historical parameter values accounting for historical parameter information. the parameter values are arranged in matrix form and reordered. The reorder matrix equation is reduced by eliminating certain of the parameter values, thereby forming a reduced model. When the reduced model is incorporated is a system model it is necessary to modify the system model to account to the component model current parameter information. Such information is used by the component model to update the historical information.

摘要： A one-terminal process for locating a fault associated with a multi-phase electric power transmission system is disclosed. The process is based on the principle that the impedance in a fault can be determined by correcting errors due to the interaction of fault resistance and load current. The fault may be a phase-to-ground fault or a multiple-phase fault.

摘要： A system and method for automatically testing the operation of a protective relay system is disclosed. The system and method provide for continuous testing to ensure proper operation of the protective relay system while the relay remains in service and without interrupting the normal operation of the relay. This testing is performed by storing reference data corresponding to test signals, generating test signals, sampling a specific test signal, processing that test signal through the relay and comparing the processed test signal with the corresponding reference data. Upon detection of an error in the relay, the system and method further provide for isolation of the relay from the electric power system and automatic testing of individual electrical components within the protective relay system to determine the identity of the malfunctioning component. The method of determining the malfunctioning component requires: selecting a component for testing, generating a test signal, providing the test signal as an input to the selected component, processing the test signal through the selected component and the subsequent component in the protective relay system and comparing the processed test signal with corresponding reference data. Finally, the system and method further provide for automatic correction of the malfunctioning component, if possible.

摘要： A high voltage open-air switch has a movable disconnect switch blade which contains a circuit interrupter therein having interrupter contacts in series with the open air disconnect switch contacts. The circuit interrupter has a lower BIL rating than the switch. An operating mechanism causes the independent operation of the interrupter and disconnect switch such that there is a high speed opening of the interrupter contacts, followed by the low speed opening of the disconnect switch contacts, and a slow speed closing of the disconnect switch contacts followed by the high speed closing of the interrupter contacts. The switch can be adapted to numerous switch configurations and permits substantial savings in space by the reduced mounting space requirements for the interrupter assembly.

摘要： A load tap changer (LTC) comprising in part a diverter switch is disclosed. The diverter switch includes a movable main contact (38); first and second fixed main contacts (40a, 40b); a pantograph system (30) for translating a rotational motion of a shaft (22) to a substantially linear motion of the movable main contact; and a link system (10) comprising a gear (12) adapted to be rotated by a motor, a spring battery (26) for storing energy of the motor, link means (14, 16, 18) for coupling the gear to the spring battery, and the shaft (22) coupled to the link means, wherein the spring battery is operable to rotate the shaft and to thereby effect the movement of the movable main contact. A predetermined amount of rotation of the shaft effects a movement of the movable main contact from a contacting relation with the first fixed main contact to a contacting relation with the second fixed main contact.
