  • Atlas is a pulsed-power facility under development at Los Alamos National Laboratory to drive high-energy density experiments. Design has been completed for this new generation pulsed-power machine consisting of an azimuthal array of 24, 240-kV Marx modules and transmission lines supplying current to the load region at the machine center. The transmission line consists of a cable header, load protection switch, and tri-plate assembly interfacing to the center transition section. The cable header interface to the Marx module provides a mechanism to remove the Marx module for maintenance without removing other components of the transmission line. The load protection switchmore » provides a mechanism for protecting the load during charging of the Marx in the event of a pre-fire condition. The aluminum tri-plate is a low-inductance transmission line carries radial current flow from the Marx energy storage system at the machine periphery toward the load. All transmission line components are oil insulated except the solid-dielectric insulated power flow channel connected directly to the load. The transition region at the machine center consists of several components that enable the radial converging vertical transmission lines to interface to a horizontal disk/conical power flow channel delivering current to the load. The current carrying transition components include the high-voltage and ground conductors interfacing to the tri-plate transmission lines. The tri-plate tank attachment ring interfaces to the tri-plate tanks and the base-plate. The base-plate supports the transition components and interfaces to the center support structure of the machine. The bottom insulator also attaches to the base-plate and to the high-voltage conductor, providing an oil containment seal between the transition and vacuum vessel. Design has been completed for all Atlas components. Some prototype hardware fabrication has been completed and first article hardware is in various stages of completion . The first article is a single line of the machine and includes a Marx module, cable header, load protection switch, tri-plate transmission line, and a dump load for testing. Testing is in progress on some prototype and first article components to verify performance before production begins on critical system components. Production will soon begin for much of the overall system, including the Marx tanks, tri-plate tanks, support structure, some transition components, and the personnel platform. These components will be fabricated and installed while the remaining internal components are being fabricated.« less
  • Calculations are presented for the unperturbed electric field between parallel plates of various configurations. Also, the calculated perturbation caused by a conductive object placed between the plates is compared with the corresponding perturbation in a transmission line field. Conclusions on the performance of laboratory parallel plate arrangements used for the study of electric-field related biological effects are given. Calculations are compared with actual field measurements done by others, and show very good agreement.
  • A review of an Electric Power Reserch Institute (EPRI) project to develop design aids for the calculation of longitudinal forces and displacements in transmission line structures caused by broken wire or differential ice disturbances is presented. Emphasis is given to results from an equilibrium solution based on a nonlinear stiffness analysis of the line system in which flexibility of the support structures is considered. An outline of a recommended procedure for design of a line system utilizing aids developed in the course of this work is also presented.
  • This paper demonstrates how a finite element model which exploits domain decomposition is applied to the analysis of three-phase induction motors. It is shown that a significant gain in cpu time results when compared with standard finite element analysis. Aspects of the application of the method which are particular to induction motors are considered: the means of improving the convergence of the nonlinear finite element equations; the choice of symmetrical sub-domains; the modelling of relative movement; and the inclusion of periodic boundary conditions.
  • This paper reports the Commonwealth Edison Company (CECo) has considered a double circuit 345 kV overhead transmission line extension from the south to provide load growth and improved reliability to Chicago's downtown loop area. A non-electric commuter rail right-of-way (ROW) is available for sharing along much of the preferred route. A cooperative analysis of the electromagnetic influences of a planned overhead EHV transmission line on an adjacent urban property is described. The steps involved in the analysis are identified, including computer modeling and validation measurements, electromagnetic susceptibility and electrical safety estimates, methods for identifying potential interference, and mitigation options wheremore » required.« less
