Frequency dependence of partial discharge initiation voltages with embedded electrodes
Partial discharge initiation voltages of a dielectric insulation material exposed to ac voltages show little dependence on frequency in the power frequency range. This results after significant voltage conditioning at the ...
Higher frequency performance of stress-grading systems for HV large rotating machines
(Conference on Electrical Insulation and Dielectric Phenomena, 2006)
Modeling and Simulation of Electric Ships’ Power System Components and Their Interaction
(Society for Computer Simulation International, 2007)
Models of propulsion motors, generators, gas turbines, and power converters are used to determine weights and volumes, evaluate designs, and predict performance of power system components for all-electric navy ships. The ...
Shock and vibration testing of an AMB supported energy storage flywheel
(The Japan Society of Mechanical Engineers, 2003)
Shock and vibration testing of an Active Magnetic Bearing (AMB) supported energy storage flywheel is presented. The flywheel is under development at the University of Texas-Center for Electromechanics (UT-CEM) for application ...
Modeling of Electric Ship Power Systems
(Society for Modeling & Simulation International, 2009)
The central element of a ship power system model is typically a circuit model. This level of modeling has been valuable in evaluating architectures for future electric ships as it provides initial power flow and stability ...
Working field theory problems with random walks
(Emerald Group Publishing Limited, 2005)
Abstract Purpose – The purpose of this paper is to demonstrate how Monte Carlo methods can be applied to the solution of field theory problems. Design – This objective is achieved by building insight from Laplacian field ...
Factors Contributing to Streamer Morphology
Recent work shows that the range of morphology of anode streamers in liquid dielectric breakdown is predicted when it is represented as stochastic growth of a branching fractal tree. This model may be analogous to the ...
NIST and the CEIDP - Working Together to Advance Technology
The technology underpinning the electrification and the growth of telecommunications in the United States stimulated a long-term relationship between the Conference on Electrical Insulation and Dielectric Phenomena and the ...
Power Systems Study for Two Variable Specific Impulse Magnetoplasma Rocket Applications
(American Society of Civil Engineers, 2002)
In this study, we analyze the power storage systems needed for operational tests of a Variable Specific Impulse Magnetoplasma Rocket (VASIMR) on the International Space Station (ISS). Two tests are considered: a short-term ...
A Simulation-Based Design Study for a Locomotive Electric Power System
This paper presents a model and simulation for a conceptual locomotive power system consisting of a gas turbine driven synchronous alternator coupled to a rectifier – dc link – variable frequency inverter configuration. ...
